This provides a simple + S/MIME API on top of the PKCS#7 code, a MIME parser (with enough + functionality to handle multipart/signed properly) and a utility + called 'smime' to call all this stuff. This is based on code I + originally wrote for Celo who have kindly allowed it to be + included in OpenSSL. + [Steve Henson] + + *) Add variants des_set_key_checked and des_set_key_unchecked of + des_set_key (aka des_key_sched). Global variable des_check_key + decides which of these is called by des_set_key; this way + des_check_key behaves as it always did, but applications and + the library itself, which was buggy for des_check_key == 1, + have a cleaner way to pick the version they need. + [Bodo Moeller] + + *) New function PKCS12_newpass() which changes the password of a + PKCS12 structure. + [Steve Henson] + + *) Modify X509_TRUST and X509_PURPOSE so it also uses a static and + dynamic mix. In both cases the ids can be used as an index into the + table. Also modified the X509_TRUST_add() and X509_PURPOSE_add() + functions so they accept a list of the field values and the + application doesn't need to directly manipulate the X509_TRUST + structure. + [Steve Henson] + + *) Modify the ASN1_STRING_TABLE stuff so it also uses bsearch and doesn't + need initialising. + [Steve Henson] + + *) Modify the way the V3 extension code looks up extensions. This now + works in a similar way to the object code: we have some "standard" + extensions in a static table which is searched with OBJ_bsearch() + and the application can add dynamic ones if needed. The file + crypto/x509v3/ext_dat.h now has the info: this file needs to be + updated whenever a new extension is added to the core code and kept + in ext_nid order. There is a simple program 'tabtest.c' which checks + this. New extensions are not added too often so this file can readily + be maintained manually. + + There are two big advantages in doing things this way. The extensions + can be looked up immediately and no longer need to be "added" using + X509V3_add_standard_extensions(): this function now does nothing. + [Side note: I get *lots* of email saying the extension code doesn't + work because people forget to call this function] + Also no dynamic allocation is done unless new extensions are added: + so if we don't add custom extensions there is no need to call + X509V3_EXT_cleanup(). + [Steve Henson] + + *) Modify enc utility's salting as follows: make salting the default. Add a + magic header, so unsalted files fail gracefully instead of just decrypting + to garbage. This is because not salting is a big security hole, so people + should be discouraged from doing it. + [Ben Laurie] + + *) Fixes and enhancements to the 'x509' utility. It allowed a message + digest to be passed on the command line but it only used this + parameter when signing a certificate. Modified so all relevant + operations are affected by the digest parameter including the + -fingerprint and -x509toreq options. Also -x509toreq choked if a + DSA key was used because it didn't fix the digest. + [Steve Henson] + + *) Initial certificate chain verify code. Currently tests the untrusted + certificates for consistency with the verify purpose (which is set + when the X509_STORE_CTX structure is set up) and checks the pathlength. + + There is a NO_CHAIN_VERIFY compilation option to keep the old behaviour: + this is because it will reject chains with invalid extensions whereas + every previous version of OpenSSL and SSLeay made no checks at all. + + Trust code: checks the root CA for the relevant trust settings. Trust + settings have an initial value consistent with the verify purpose: e.g. + if the verify purpose is for SSL client use it expects the CA to be + trusted for SSL client use. However the default value can be changed to + permit custom trust settings: one example of this would be to only trust + certificates from a specific "secure" set of CAs. + + Also added X509_STORE_CTX_new() and X509_STORE_CTX_free() functions + which should be used for version portability: especially since the + verify structure is likely to change more often now. + + SSL integration. Add purpose and trust to SSL_CTX and SSL and functions + to set them. If not set then assume SSL clients will verify SSL servers + and vice versa. + + Two new options to the verify program: -untrusted allows a set of + untrusted certificates to be passed in and -purpose which sets the + intended purpose of the certificate. If a purpose is set then the + new chain verify code is used to check extension consistency. + [Steve Henson] + + *) Support for the authority information access extension. + [Steve Henson] + + *) Modify RSA and DSA PEM read routines to transparently handle + PKCS#8 format private keys. New *_PUBKEY_* functions that handle + public keys in a format compatible with certificate + SubjectPublicKeyInfo structures. Unfortunately there were already + functions called *_PublicKey_* which used various odd formats so + these are retained for compatability: however the DSA variants were + never in a public release so they have been deleted. Changed dsa/rsa + utilities to handle the new format: note no releases ever handled public + keys so we should be OK. + + The primary motivation for this change is to avoid the same fiasco + that dogs private keys: there are several incompatible private key + formats some of which are standard and some OpenSSL specific and + require various evil hacks to allow partial transparent handling and + even then it doesn't work with DER formats. Given the option anything + other than PKCS#8 should be dumped: but the other formats have to + stay in the name of compatability. + + With public keys and the benefit of hindsight one standard format + is used which works with EVP_PKEY, RSA or DSA structures: though + it clearly returns an error if you try to read the wrong kind of key. + + Added a -pubkey option to the 'x509' utility to output the public key. + Also rename the EVP_PKEY_get_*() to EVP_PKEY_rget_*() and add + EVP_PKEY_rset_*() functions that do the same as the EVP_PKEY_assign_*() + except they up the reference count of the added key (they don't "swallow" + the supplied key). + [Steve Henson] + + *) Fixes to crypto/x509/by_file.c the code to read in certificates and + CRLs would fail if the file contained no certificates or no CRLs: + added a new function to read in both types and return the number + read: this means that if none are read it will be an error. The + DER versions of the certificate and CRL reader would always fail + because it isn't possible to mix certificates and CRLs in DER format + without choking one or the other routine. Changed this to just read + a certificate: this is the best we can do. Also modified the code + in apps/verify.c to take notice of return codes: it was previously + attempting to read in certificates from NULL pointers and ignoring + any errors: this is one reason why the cert and CRL reader seemed + to work. It doesn't check return codes from the default certificate + routines: these may well fail if the certificates aren't installed. + [Steve Henson] + + *) Code to support otherName option in GeneralName. + [Steve Henson] + + *) First update to verify code. Change the verify utility + so it warns if it is passed a self signed certificate: + for consistency with the normal behaviour. X509_verify + has been modified to it will now verify a self signed + certificate if *exactly* the same certificate appears + in the store: it was previously impossible to trust a + single self signed certificate. This means that: + openssl verify ss.pem + now gives a warning about a self signed certificate but + openssl verify -CAfile ss.pem ss.pem + is OK. + [Steve Henson] + + *) For servers, store verify_result in SSL_SESSION data structure + (and add it to external session representation). + This is needed when client certificate verifications fails, + but an application-provided verification callback (set by + SSL_CTX_set_cert_verify_callback) allows accepting the session + anyway (i.e. leaves x509_store_ctx->error != X509_V_OK + but returns 1): When the session is reused, we have to set + ssl->verify_result to the appropriate error code to avoid + security holes. + [Bodo Moeller, problem pointed out by Lutz Jaenicke] + + *) Fix a bug in the new PKCS#7 code: it didn't consider the + case in PKCS7_dataInit() where the signed PKCS7 structure + didn't contain any existing data because it was being created. + [Po-Cheng Chen , slightly modified by Steve Henson] + + *) Add a salt to the key derivation routines in enc.c. This + forms the first 8 bytes of the encrypted file. Also add a + -S option to allow a salt to be input on the command line. + [Steve Henson] + + *) New function X509_cmp(). Oddly enough there wasn't a function + to compare two certificates. We do this by working out the SHA1 + hash and comparing that. X509_cmp() will be needed by the trust + code. + [Steve Henson] + + *) Correctly increment the reference count in the SSL_SESSION pointer + returned from SSL_get_session(). + [Geoff Thorpe ] + + *) Fix for 'req': it was adding a null to request attributes. + Also change the X509_LOOKUP and X509_INFO code to handle + certificate auxiliary information. + [Steve Henson] + + *) Add support for 40 and 64 bit RC2 and RC4 algorithms: document + the 'enc' command. + [Steve Henson] + + *) Add the possibility to add extra information to the memory leak + detecting output, to form tracebacks, showing from where each + allocation was originated. Also updated sid code to be multi- + thread-safe. + [Richard Levitte] + + *) Add options -text and -noout to pkcs7 utility and delete the + encryption options which never did anything. Update docs. + [Steve Henson] + + *) Add options to some of the utilities to allow the pass phrase + to be included on either the command line (not recommended on + OSes like Unix) or read from the environment. Update the + manpages and fix a few bugs. + [Steve Henson] + + *) Add a few manpages for some of the openssl commands. + [Steve Henson] + + *) Fix the -revoke option in ca. It was freeing up memory twice, + leaking and not finding already revoked certificates. + [Steve Henson] + + *) Extensive changes to support certificate auxiliary information. + This involves the use of X509_CERT_AUX structure and X509_AUX + functions. An X509_AUX function such as PEM_read_X509_AUX() + can still read in a certificate file in the usual way but it + will also read in any additional "auxiliary information". By + doing things this way a fair degree of compatability can be + retained: existing certificates can have this information added + using the new 'x509' options. + + Current auxiliary information includes an "alias" and some trust + settings. The trust settings will ultimately be used in enhanced + certificate chain verification routines: currently a certificate + can only be trusted if it is self signed and then it is trusted + for all purposes. + [Steve Henson] + + *) Fix assembler for Alpha (tested only on DEC OSF not Linux or *BSD). The + problem was that one of the replacement routines had not been working since + SSLeay releases. For now the offending routine has been replaced with + non-optimised assembler. Even so, this now gives around 95% performance + improvement for 1024 bit RSA signs. + [Mark Cox] + + *) Hack to fix PKCS#7 decryption when used with some unorthodox RC2 + handling. Most clients have the effective key size in bits equal to + the key length in bits: so a 40 bit RC2 key uses a 40 bit (5 byte) key. + A few however don't do this and instead use the size of the decrypted key + to determine the RC2 key length and the AlgorithmIdentifier to determine + the effective key length. In this case the effective key lenth can still + be 40 bits but the key length can be 168 bits for example. This is fixed + by manually forcing an RC2 key into the EVP_PKEY structure because the + EVP code can't currently handle unusual RC2 key sizes: it always assumes + the key length and effective key length are equal. + [Steve Henson] + + *) Add a bunch of functions that should simplify the creation of + X509_NAME structures. Now you should be able to do: + X509_NAME_add_entry_by_txt(nm, "CN", MBSTRING_ASC, "Steve", -1, -1, 0); + and have it automatically work out the correct field type and fill in + the structures. The more adventurous can try: + X509_NAME_add_entry_by_txt(nm, field, MBSTRING_UTF8, str, -1, -1, 0); + and it will (hopefully) work out the correct multibyte encoding. + [Steve Henson] + + *) Change the 'req' utility to use the new field handling and multibyte + copy routines. Before the DN field creation was handled in an ad hoc + way in req, ca, and x509 which was rather broken and didn't support + BMPStrings or UTF8Strings. Since some software doesn't implement + BMPStrings or UTF8Strings yet, they can be enabled using the config file + using the dirstring_type option. See the new comment in the default + openssl.cnf for more info. + [Steve Henson] + + *) Make crypto/rand/md_rand.c more robust: + - Assure unique random numbers after fork(). + - Make sure that concurrent threads access the global counter and + md serializably so that we never lose entropy in them + or use exactly the same state in multiple threads. + Access to the large state is not always serializable because + the additional locking could be a performance killer, and + md should be large enough anyway. + [Bodo Moeller] + + *) New file apps/app_rand.c with commonly needed functionality + for handling the random seed file. + + Use the random seed file in some applications that previously did not: + ca, + dsaparam -genkey (which also ignored its `-rand' option), + s_client, + s_server, + x509 (when signing). + Except on systems with /dev/urandom, it is crucial to have a random + seed file at least for key creation, DSA signing, and for DH exchanges; + for RSA signatures we could do without one. + + gendh and gendsa (unlike genrsa) used to read only the first byte + of each file listed in the `-rand' option. The function as previously + found in genrsa is now in app_rand.c and is used by all programs + that support `-rand'. + [Bodo Moeller] + + *) In RAND_write_file, use mode 0600 for creating files; + don't just chmod when it may be too late. + [Bodo Moeller] + + *) Report an error from X509_STORE_load_locations + when X509_LOOKUP_load_file or X509_LOOKUP_add_dir failed. + [Bill Perry] + + *) New function ASN1_mbstring_copy() this copies a string in either + ASCII, Unicode, Universal (4 bytes per character) or UTF8 format + into an ASN1_STRING type. A mask of permissible types is passed + and it chooses the "minimal" type to use or an error if not type + is suitable. + [Steve Henson] + + *) Add function equivalents to the various macros in asn1.h. The old + macros are retained with an M_ prefix. Code inside the library can + use the M_ macros. External code (including the openssl utility) + should *NOT* in order to be "shared library friendly". + [Steve Henson] + + *) Add various functions that can check a certificate's extensions + to see if it usable for various purposes such as SSL client, + server or S/MIME and CAs of these types. This is currently + VERY EXPERIMENTAL but will ultimately be used for certificate chain + verification. Also added a -purpose flag to x509 utility to + print out all the purposes. + [Steve Henson] + + *) Add a CRYPTO_EX_DATA to X509 certificate structure and associated + functions. + [Steve Henson] + + *) New X509V3_{X509,CRL,REVOKED}_get_d2i() functions. These will search + for, obtain and decode and extension and obtain its critical flag. + This allows all the necessary extension code to be handled in a + single function call. + [Steve Henson] + + *) RC4 tune-up featuring 30-40% performance improvement on most RISC + platforms. See crypto/rc4/rc4_enc.c for further details. + [Andy Polyakov] + + *) New -noout option to asn1parse. This causes no output to be produced + its main use is when combined with -strparse and -out to extract data + from a file (which may not be in ASN.1 format). + [Steve Henson] + + *) Fix for pkcs12 program. It was hashing an invalid certificate pointer + when producing the local key id. + [Richard Levitte ] + + *) New option -dhparam in s_server. This allows a DH parameter file to be + stated explicitly. If it is not stated then it tries the first server + certificate file. The previous behaviour hard coded the filename + "server.pem". + [Steve Henson] + + *) Add -pubin and -pubout options to the rsa and dsa commands. These allow + a public key to be input or output. For example: + openssl rsa -in key.pem -pubout -out pubkey.pem + Also added necessary DSA public key functions to handle this. + [Steve Henson] + + *) Fix so PKCS7_dataVerify() doesn't crash if no certificates are contained + in the message. This was handled by allowing + X509_find_by_issuer_and_serial() to tolerate a NULL passed to it. + [Steve Henson, reported by Sampo Kellomaki ] + + *) Fix for bug in d2i_ASN1_bytes(): other ASN1 functions add an extra null + to the end of the strings whereas this didn't. This would cause problems + if strings read with d2i_ASN1_bytes() were later modified. + [Steve Henson, reported by Arne Ansper ] + + *) Fix for base64 decode bug. When a base64 bio reads only one line of + data and it contains EOF it will end up returning an error. This is + caused by input 46 bytes long. The cause is due to the way base64 + BIOs find the start of base64 encoded data. They do this by trying a + trial decode on each line until they find one that works. When they + do a flag is set and it starts again knowing it can pass all the + data directly through the decoder. Unfortunately it doesn't reset + the context it uses. This means that if EOF is reached an attempt + is made to pass two EOFs through the context and this causes the + resulting error. This can also cause other problems as well. As is + usual with these problems it takes *ages* to find and the fix is + trivial: move one line. + [Steve Henson, reported by ian@uns.ns.ac.yu (Ivan Nejgebauer) ] + + *) Ugly workaround to get s_client and s_server working under Windows. The + old code wouldn't work because it needed to select() on sockets and the + tty (for keypresses and to see if data could be written). Win32 only + supports select() on sockets so we select() with a 1s timeout on the + sockets and then see if any characters are waiting to be read, if none + are present then we retry, we also assume we can always write data to + the tty. This isn't nice because the code then blocks until we've + received a complete line of data and it is effectively polling the + keyboard at 1s intervals: however it's quite a bit better than not + working at all :-) A dedicated Windows application might handle this + with an event loop for example. + [Steve Henson] + + *) Enhance RSA_METHOD structure. Now there are two extra methods, rsa_sign + and rsa_verify. When the RSA_FLAGS_SIGN_VER option is set these functions + will be called when RSA_sign() and RSA_verify() are used. This is useful + if rsa_pub_dec() and rsa_priv_enc() equivalents are not available. + For this to work properly RSA_public_decrypt() and RSA_private_encrypt() + should *not* be used: RSA_sign() and RSA_verify() must be used instead. + This necessitated the support of an extra signature type NID_md5_sha1 + for SSL signatures and modifications to the SSL library to use it instead + of calling RSA_public_decrypt() and RSA_private_encrypt(). + [Steve Henson] + + *) Add new -verify -CAfile and -CApath options to the crl program, these + will lookup a CRL issuers certificate and verify the signature in a + similar way to the verify program. Tidy up the crl program so it + no longer acesses structures directly. Make the ASN1 CRL parsing a bit + less strict. It will now permit CRL extensions even if it is not + a V2 CRL: this will allow it to tolerate some broken CRLs. + [Steve Henson] + + *) Initialize all non-automatic variables each time one of the openssl + sub-programs is started (this is necessary as they may be started + multiple times from the "OpenSSL>" prompt). + [Lennart Bang, Bodo Moeller] + + *) Preliminary compilation option RSA_NULL which disables RSA crypto without + removing all other RSA functionality (this is what NO_RSA does). This + is so (for example) those in the US can disable those operations covered + by the RSA patent while allowing storage and parsing of RSA keys and RSA + key generation. + [Steve Henson] + + *) Non-copying interface to BIO pairs. + (still largely untested) + [Bodo Moeller] + + *) New function ANS1_tag2str() to convert an ASN1 tag to a descriptive + ASCII string. This was handled independently in various places before. + [Steve Henson] + + *) New functions UTF8_getc() and UTF8_putc() that parse and generate + UTF8 strings a character at a time. + [Steve Henson] + + *) Use client_version from client hello to select the protocol + (s23_srvr.c) and for RSA client key exchange verification + (s3_srvr.c), as required by the SSL 3.0/TLS 1.0 specifications. + [Bodo Moeller] + + *) Add various utility functions to handle SPKACs, these were previously + handled by poking round in the structure internals. Added new function + NETSCAPE_SPKI_print() to print out SPKAC and a new utility 'spkac' to + print, verify and generate SPKACs. Based on an original idea from + Massimiliano Pala but extensively modified. + [Steve Henson] + + *) RIPEMD160 is operational on all platforms and is back in 'make test'. + [Andy Polyakov] + + *) Allow the config file extension section to be overwritten on the + command line. Based on an original idea from Massimiliano Pala + . The new option is called -extensions + and can be applied to ca, req and x509. Also -reqexts to override + the request extensions in req and -crlexts to override the crl extensions + in ca. + [Steve Henson] + + *) Add new feature to the SPKAC handling in ca. Now you can include + the same field multiple times by preceding it by "XXXX." for example: + 1.OU="Unit name 1" + 2.OU="Unit name 2" + this is the same syntax as used in the req config file. + [Steve Henson] + + *) Allow certificate extensions to be added to certificate requests. These + are specified in a 'req_extensions' option of the req section of the + config file. They can be printed out with the -text option to req but + are otherwise ignored at present. + [Steve Henson] + + *) Fix a horrible bug in enc_read() in crypto/evp/bio_enc.c: if the first + data read consists of only the final block it would not decrypted because + EVP_CipherUpdate() would correctly report zero bytes had been decrypted. + A misplaced 'break' also meant the decrypted final block might not be + copied until the next read. + [Steve Henson] + + *) Initial support for DH_METHOD. Again based on RSA_METHOD. Also added + a few extra parameters to the DH structure: these will be useful if + for example we want the value of 'q' or implement X9.42 DH. + [Steve Henson] + + *) Initial support for DSA_METHOD. This is based on the RSA_METHOD and + provides hooks that allow the default DSA functions or functions on a + "per key" basis to be replaced. This allows hardware acceleration and + hardware key storage to be handled without major modification to the + library. Also added low level modexp hooks and CRYPTO_EX structure and + associated functions. + [Steve Henson] + + *) Add a new flag to memory BIOs, BIO_FLAG_MEM_RDONLY. This marks the BIO + as "read only": it can't be written to and the buffer it points to will + not be freed. Reading from a read only BIO is much more efficient than + a normal memory BIO. This was added because there are several times when + an area of memory needs to be read from a BIO. The previous method was + to create a memory BIO and write the data to it, this results in two + copies of the data and an O(n^2) reading algorithm. There is a new + function BIO_new_mem_buf() which creates a read only memory BIO from + an area of memory. Also modified the PKCS#7 routines to use read only + memory BIOSs. + [Steve Henson] + + *) Bugfix: ssl23_get_client_hello did not work properly when called in + state SSL23_ST_SR_CLNT_HELLO_B, i.e. when the first 7 bytes of + a SSLv2-compatible client hello for SSLv3 or TLSv1 could be read, + but a retry condition occured while trying to read the rest. + [Bodo Moeller] + + *) The PKCS7_ENC_CONTENT_new() function was setting the content type as + NID_pkcs7_encrypted by default: this was wrong since this should almost + always be NID_pkcs7_data. Also modified the PKCS7_set_type() to handle + the encrypted data type: this is a more sensible place to put it and it + allows the PKCS#12 code to be tidied up that duplicated this + functionality. + [Steve Henson] + + *) Changed obj_dat.pl script so it takes its input and output files on + the command line. This should avoid shell escape redirection problems + under Win32. + [Steve Henson] + + *) Initial support for certificate extension requests, these are included + in things like Xenroll certificate requests. Included functions to allow + extensions to be obtained and added. + [Steve Henson] + + *) -crlf option to s_client and s_server for sending newlines as + CRLF (as required by many protocols). + [Bodo Moeller] + + Changes between 0.9.3a and 0.9.4 [09 Aug 1999] + + *) Install libRSAglue.a when OpenSSL is built with RSAref. + [Ralf S. Engelschall] + + *) A few more ``#ifndef NO_FP_API / #endif'' pairs for consistency. + [Andrija Antonijevic ] + + *) Fix -startdate and -enddate (which was missing) arguments to 'ca' + program. + [Steve Henson] + + *) New function DSA_dup_DH, which duplicates DSA parameters/keys as + DH parameters/keys (q is lost during that conversion, but the resulting + DH parameters contain its length). + + For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is + much faster than DH_generate_parameters (which creates parameters + where p = 2*q + 1), and also the smaller q makes DH computations + much more efficient (160-bit exponentiation instead of 1024-bit + exponentiation); so this provides a convenient way to support DHE + ciphersuites in SSL/TLS servers (see ssl/ssltest.c). It is of + utter importance to use + SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE); + or + SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE); + when such DH parameters are used, because otherwise small subgroup + attacks may become possible! + [Bodo Moeller] + + *) Avoid memory leak in i2d_DHparams. + [Bodo Moeller] + + *) Allow the -k option to be used more than once in the enc program: + this allows the same encrypted message to be read by multiple recipients. + [Steve Henson] + + *) New function OBJ_obj2txt(buf, buf_len, a, no_name), this converts + an ASN1_OBJECT to a text string. If the "no_name" parameter is set then + it will always use the numerical form of the OID, even if it has a short + or long name. + [Steve Henson] + + *) Added an extra RSA flag: RSA_FLAG_EXT_PKEY. Previously the rsa_mod_exp + method only got called if p,q,dmp1,dmq1,iqmp components were present, + otherwise bn_mod_exp was called. In the case of hardware keys for example + no private key components need be present and it might store extra data + in the RSA structure, which cannot be accessed from bn_mod_exp. + By setting RSA_FLAG_EXT_PKEY rsa_mod_exp will always be called for + private key operations. + [Steve Henson] + + *) Added support for SPARC Linux. + [Andy Polyakov] + + *) pem_password_cb function type incompatibly changed from + typedef int pem_password_cb(char *buf, int size, int rwflag); + to + ....(char *buf, int size, int rwflag, void *userdata); + so that applications can pass data to their callbacks: + The PEM[_ASN1]_{read,write}... functions and macros now take an + additional void * argument, which is just handed through whenever + the password callback is called. + [Damien Miller ; tiny changes by Bodo Moeller] + + New function SSL_CTX_set_default_passwd_cb_userdata. + + Compatibility note: As many C implementations push function arguments + onto the stack in reverse order, the new library version is likely to + interoperate with programs that have been compiled with the old + pem_password_cb definition (PEM_whatever takes some data that + happens to be on the stack as its last argument, and the callback + just ignores this garbage); but there is no guarantee whatsoever that + this will work. + + *) The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=... + (both in crypto/Makefile.ssl for use by crypto/cversion.c) caused + problems not only on Windows, but also on some Unix platforms. + To avoid problematic command lines, these definitions are now in an + auto-generated file crypto/buildinf.h (created by crypto/Makefile.ssl + for standard "make" builds, by util/mk1mf.pl for "mk1mf" builds). + [Bodo Moeller] + + *) MIPS III/IV assembler module is reimplemented. + [Andy Polyakov] *) More DES library cleanups: remove references to srand/rand and delete an unused file.
