This + is needed for applications which have to configure certificates on a + per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis + (e.g. s_server). + For the RSA certificate situation is makes no difference, but + for the DSA certificate situation this fixes the "no shared cipher" + problem where the OpenSSL cipher selection procedure failed because the + temporary keys were not overtaken from the context and the API provided + no way to reconfigure them. + The new functions now let applications reconfigure the stuff and they + are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh, + SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new + non-public-API function ssl_cert_instantiate() is used as a helper + function and also to reduce code redundancy inside ssl_rsa.c. + [Ralf S. Engelschall] + + *) Move s_server -dcert and -dkey options out of the undocumented feature + area because they are useful for the DSA situation and should be + recognized by the users. + [Ralf S. Engelschall] + + *) Fix the cipher decision scheme for export ciphers: the export bits are + *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within + SSL_EXP_MASK. So, the original variable has to be used instead of the + already masked variable. + [Richard Levitte ] + + *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c + [Richard Levitte ] + + *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal() + from `int' to `unsigned int' because it's a length and initialized by + EVP_DigestFinal() which expects an `unsigned int *'. + [Richard Levitte ] + + *) Don't hard-code path to Perl interpreter on shebang line of Configure + script. Instead use the usual Shell->Perl transition trick. + [Ralf S. Engelschall] + + *) Make `openssl x509 -noout -modulus' functional also for DSA certificates + (in addition to RSA certificates) to match the behaviour of `openssl dsa + -noout -modulus' as it's already the case for `openssl rsa -noout + -modulus'. For RSA the -modulus is the real "modulus" while for DSA + currently the public key is printed (a decision which was already done by + `openssl dsa -modulus' in the past) which serves a similar purpose. + Additionally the NO_RSA no longer completely removes the whole -modulus + option; it now only avoids using the RSA stuff. Same applies to NO_DSA + now, too. + [Ralf S. Engelschall] + + *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested + BIO. See the source (crypto/evp/bio_ok.c) for more info. + [Arne Ansper ] + + *) Dump the old yucky req code that tried (and failed) to allow raw OIDs + to be added. Now both 'req' and 'ca' can use new objects defined in the + config file. + [Steve Henson] + + *) Add cool BIO that does syslog (or event log on NT). + [Arne Ansper , integrated by Ben Laurie] + + *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5, + TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and + TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher + Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt. + [Ben Laurie] + + *) Add preliminary config info for new extension code. + [Steve Henson] + + *) Make RSA_NO_PADDING really use no padding. + [Ulf Moeller ] + + *) Generate errors when private/public key check is done. + [Ben Laurie] + + *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support + for some CRL extensions and new objects added. + [Steve Henson] + + *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private + key usage extension and fuller support for authority key id. + [Steve Henson] + + *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved + padding method for RSA, which is recommended for new applications in PKCS + #1 v2.0 (RFC 2437, October 1998). + OAEP (Optimal Asymmetric Encryption Padding) has better theoretical + foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure + against Bleichbacher's attack on RSA. + [Ulf Moeller , reformatted, corrected and integrated by + Ben Laurie] + + *) Updates to the new SSL compression code + [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)] + + *) Fix so that the version number in the master secret, when passed + via RSA, checks that if TLS was proposed, but we roll back to SSLv3 + (because the server will not accept higher), that the version number + is 0x03,0x01, not 0x03,0x00 + [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)] + + *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory + leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes + in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c + [Steve Henson] + + *) Support for RAW extensions where an arbitrary extension can be + created by including its DER encoding. See apps/openssl.cnf for + an example. + [Steve Henson] + + *) Make sure latest Perl versions don't interpret some generated C array + code as Perl array code in the crypto/err/err_genc.pl script. + [Lars Weber <3weber@informatik.uni-hamburg.de>] + + *) Modify ms/do_ms.bat to not generate assembly language makefiles since + not many people have the assembler. Various Win32 compilation fixes and + update to the INSTALL.W32 file with (hopefully) more accurate Win32 + build instructions. + [Steve Henson] + + *) Modify configure script 'Configure' to automatically create crypto/date.h + file under Win32 and also build pem.h from pem.org. New script + util/mkfiles.pl to create the MINFO file on environments that can't do a + 'make files': perl util/mkfiles.pl >MINFO should work. + [Steve Henson] + + *) Major rework of DES function declarations, in the pursuit of correctness + and purity. As a result, many evil casts evaporated, and some weirdness, + too. You may find this causes warnings in your code. Zapping your evil + casts will probably fix them. Mostly. + [Ben Laurie] + + *) Fix for a typo in asn1.h. Bug fix to object creation script + obj_dat.pl. It considered a zero in an object definition to mean + "end of object": none of the objects in objects.h have any zeros + so it wasn't spotted. + [Steve Henson, reported by Erwann ABALEA ] + + *) Add support for Triple DES Cipher Block Chaining with Output Feedback + Masking (CBCM). In the absence of test vectors, the best I have been able + to do is check that the decrypt undoes the encrypt, so far. Send me test + vectors if you have them. + [Ben Laurie] + + *) Correct caclulation of key length for export ciphers (too much space was + allocated for null ciphers). This has not been tested! + [Ben Laurie] + + *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage + message is now correct (it understands "crypto" and "ssl" on its + command line). There is also now an "update" option. This will update + the util/ssleay.num and util/libeay.num files with any new functions. + If you do a: + perl util/mkdef.pl crypto ssl update + it will update them. + [Steve Henson] + + *) Overhauled the Perl interface (perl/*): + - ported BN stuff to OpenSSL's different BN library + - made the perl/ source tree CVS-aware + - renamed the package from SSLeay to OpenSSL (the files still contain + their history because I've copied them in the repository) + - removed obsolete files (the test scripts will be replaced + by better Test::Harness variants in the future) + [Ralf S. Engelschall] + + *) First cut for a very conservative source tree cleanup: + 1. merge various obsolete readme texts into doc/ssleay.txt + where we collect the old documents and readme texts. + 2. remove the first part of files where I'm already sure that we no + longer need them because of three reasons: either they are just temporary + files which were left by Eric or they are preserved original files where + I've verified that the diff is also available in the CVS via "cvs diff + -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for + the crypto/md/ stuff). + [Ralf S. Engelschall] + + *) More extension code. Incomplete support for subject and issuer alt + name, issuer and authority key id. Change the i2v function parameters + and add an extra 'crl' parameter in the X509V3_CTX structure: guess + what that's for :-) Fix to ASN1 macro which messed up + IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED. + [Steve Henson] + + *) Preliminary support for ENUMERATED type. This is largely copied from the + INTEGER code. + [Steve Henson] + + *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy. + [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)] + + *) Make sure `make rehash' target really finds the `openssl' program. + [Ralf S. Engelschall, Matthias Loepfe ] + + *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd + like to hear about it if this slows down other processors. + [Ben Laurie] + + *) Add CygWin32 platform information to Configure script. + [Alan Batie ] + + *) Fixed ms/32all.bat script: `no_asm' -> `no-asm' + [Rainer W. Gerling ] + + *) New program nseq to manipulate netscape certificate sequences + [Steve Henson] + + *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a + few typos. + [Steve Henson] + + *) Fixes to BN code. Previously the default was to define BN_RECURSION + but the BN code had some problems that would cause failures when + doing certificate verification and some other functions. + [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)] + + *) Add ASN1 and PEM code to support netscape certificate sequences. + [Steve Henson] + + *) Add ASN1 and PEM code to support netscape certificate sequences. + [Steve Henson] + + *) Add several PKIX and private extended key usage OIDs. + [Steve Henson] + + *) Modify the 'ca' program to handle the new extension code. Modify + openssl.cnf for new extension format, add comments. + [Steve Henson] + + *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req' + and add a sample to openssl.cnf so req -x509 now adds appropriate + CA extensions. + [Steve Henson] + + *) Continued X509 V3 changes. Add to other makefiles, integrate with the + error code, add initial support to X509_print() and x509 application. + [Steve Henson] + + *) Takes a deep breath and start addding X509 V3 extension support code. Add + files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this + stuff is currently isolated and isn't even compiled yet. + [Steve Henson] + + *) Continuing patches for GeneralizedTime. Fix up certificate and CRL + ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print. + Removed the versions check from X509 routines when loading extensions: + this allows certain broken certificates that don't set the version + properly to be processed. + [Steve Henson] + + *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another + Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which + can still be regenerated with "make depend". + [Ben Laurie] + + *) Spelling mistake in C version of CAST-128. + [Ben Laurie, reported by Jeremy Hylton ] + + *) Changes to the error generation code. The perl script err-code.pl + now reads in the old error codes and retains the old numbers, only + adding new ones if necessary. It also only changes the .err files if new + codes are added. The makefiles have been modified to only insert errors + when needed (to avoid needlessly modifying header files). This is done + by only inserting errors if the .err file is newer than the auto generated + C file. To rebuild all the error codes from scratch (the old behaviour) + either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl + or delete all the .err files. + [Steve Henson] + + *) CAST-128 was incorrectly implemented for short keys. The C version has + been fixed, but is untested. The assembler versions are also fixed, but + new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing + to regenerate it if needed. + [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun + Hagino ] + + *) File was opened incorrectly in randfile.c. + [Ulf Möller ] + + *) Beginning of support for GeneralizedTime. d2i, i2d, check and print + functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or + GeneralizedTime. ASN1_TIME is the proper type used in certificates et + al: it's just almost always a UTCTime. Note this patch adds new error + codes so do a "make errors" if there are problems. + [Steve Henson] + + *) Correct Linux 1 recognition in config. + [Ulf Möller ] + + *) Remove pointless MD5 hash when using DSA keys in ca. + [Anonymous ] + + *) Generate an error if given an empty string as a cert directory. Also + generate an error if handed NULL (previously returned 0 to indicate an + error, but didn't set one). + [Ben Laurie, reported by Anonymous ] + + *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last. + [Ben Laurie] + + *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct + parameters. This was causing a warning which killed off the Win32 compile. + [Steve Henson] + + *) Remove C++ style comments from crypto/bn/bn_local.h. + [Neil Costigan ] + + *) The function OBJ_txt2nid was broken. It was supposed to return a nid + based on a text string, looking up short and long names and finally + "dot" format. The "dot" format stuff didn't work. Added new function + OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote + OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the + OID is not part of the table. + [Steve Henson] + + *) Add prototypes to X509 lookup/verify methods, fixing a bug in + X509_LOOKUP_by_alias(). + [Ben Laurie] + + *) Sort openssl functions by name. + [Ben Laurie] + + *) Get the gendsa program working (hopefully) and add it to app list. Remove + encryption from sample DSA keys (in case anyone is interested the password + was "1234"). + [Steve Henson] + + *) Make _all_ *_free functions accept a NULL pointer. + [Frans Heymans ] + + *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use + NULL pointers. + [Anonymous ] + + *) s_server should send the CAfile as acceptable CAs, not its own cert. + [Bodo Moeller <3moeller@informatik.uni-hamburg.de>] + + *) Don't blow it for numeric -newkey arguments to apps/req. + [Bodo Moeller <3moeller@informatik.uni-hamburg.de>] + + *) Temp key "for export" tests were wrong in s3_srvr.c. + [Anonymous ] + + *) Add prototype for temp key callback functions + SSL_CTX_set_tmp_{rsa,dh}_callback(). + [Ben Laurie] + + *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and + DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey(). + [Steve Henson] + + *) X509_name_add_entry() freed the wrong thing after an error. + [Arne Ansper ] + + *) rsa_eay.c would attempt to free a NULL context. + [Arne Ansper ] + + *) BIO_s_socket() had a broken should_retry() on Windoze. + [Arne Ansper ] + + *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH. + [Arne Ansper ] + + *) Make sure the already existing X509_STORE->depth variable is initialized + in X509_STORE_new(), but document the fact that this variable is still + unused in the certificate verification process. + [Ralf S. Engelschall] + + *) Fix the various library and apps files to free up pkeys obtained from + X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions. + [Steve Henson] + + *) Fix reference counting in X509_PUBKEY_get(). This makes + demos/maurice/example2.c work, amongst others, probably. + [Steve Henson and Ben Laurie] + + *) First cut of a cleanup for apps/. First the `ssleay' program is now named + `openssl' and second, the shortcut symlinks for the `openssl ' + are no longer created. This way we have a single and consistent command + line interface `openssl ', similar to `cvs '. + [Ralf S. Engelschall, Paul Sutton and Ben Laurie] + + *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey + BIT STRING wrapper always have zero unused bits. + [Steve Henson] + + *) Add CA.pl, perl version of CA.sh, add extended key usage OID. + [Steve Henson] + *) Make the top-level INSTALL documentation easier to understand.
