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 , with 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. + [Ulf Möller] + + *) Add support for the the free Netwide assembler (NASM) under Win32, + since not many people have MASM (ml) and it can be hard to obtain. + This is currently experimental but it seems to work OK and pass all + the tests. Check out INSTALL.W32 for info. + [Steve Henson] + + *) Fix memory leaks in s3_clnt.c: All non-anonymous SSL3/TLS1 connections + without temporary keys kept an extra copy of the server key, + and connections with temporary keys did not free everything in case + of an error. + [Bodo Moeller] + + *) New function RSA_check_key and new openssl rsa option -check + for verifying the consistency of RSA keys. + [Ulf Moeller, Bodo Moeller] + + *) Various changes to make Win32 compile work: + 1. Casts to avoid "loss of data" warnings in p5_crpt2.c + 2. Change unsigned int to int in b_dump.c to avoid "signed/unsigned + comparison" warnings. + 3. Add sk__sort to DEF file generator and do make update. + [Steve Henson] + + *) Add a debugging option to PKCS#5 v2 key generation function: when + you #define DEBUG_PKCS5V2 passwords, salts, iteration counts and + derived keys are printed to stderr. + [Steve Henson] + + *) Copy the flags in ASN1_STRING_dup(). + [Roman E. Pavlov ] + + *) The x509 application mishandled signing requests containing DSA + keys when the signing key was also DSA and the parameters didn't match. + + It was supposed to omit the parameters when they matched the signing key: + the verifying software was then supposed to automatically use the CA's + parameters if they were absent from the end user certificate. + + Omitting parameters is no longer recommended. The test was also + the wrong way round! This was probably due to unusual behaviour in + EVP_cmp_parameters() which returns 1 if the parameters match. + This meant that parameters were omitted when they *didn't* match and + the certificate was useless. Certificates signed with 'ca' didn't have + this bug. + [Steve Henson, reported by Doug Erickson ] + + *) Memory leak checking (-DCRYPTO_MDEBUG) had some problems. + The interface is as follows: + Applications can use + CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(), + CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) aka MemCheck_stop(); + "off" is now the default. + The library internally uses + CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(), + CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on() + to disable memory-checking temporarily. + + Some inconsistent states that previously were possible (and were + even the default) are now avoided. + + -DCRYPTO_MDEBUG_TIME is new and additionally stores the current time + with each memory chunk allocated; this is occasionally more helpful + than just having a counter. + + -DCRYPTO_MDEBUG_THREAD is also new and adds the thread ID. + + -DCRYPTO_MDEBUG_ALL enables all of the above, plus any future + extensions. + [Bodo Moeller] + + *) Introduce "mode" for SSL structures (with defaults in SSL_CTX), + which largely parallels "options", but is for changing API behaviour, + whereas "options" are about protocol behaviour. + Initial "mode" flags are: + + SSL_MODE_ENABLE_PARTIAL_WRITE Allow SSL_write to report success when + a single record has been written. + SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Don't insist that SSL_write + retries use the same buffer location. + (But all of the contents must be + copied!) + [Bodo Moeller] + + *) Bugfix: SSL_set_mode ignored its parameter, only SSL_CTX_set_mode + worked. + + *) Fix problems with no-hmac etc. + [Ulf Möller, pointed out by Brian Wellington ] + + *) New functions RSA_get_default_method(), RSA_set_method() and + RSA_get_method(). These allows replacement of RSA_METHODs without having + to mess around with the internals of an RSA structure. + [Steve Henson] + + *) Fix memory leaks in DSA_do_sign and DSA_is_prime. + Also really enable memory leak checks in openssl.c and in some + test programs. + [Chad C. Mulligan, Bodo Moeller] + + *) Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess + up the length of negative integers. This has now been simplified to just + store the length when it is first determined and use it later, rather + than trying to keep track of where data is copied and updating it to + point to the end. + [Steve Henson, reported by Brien Wheeler + ] + + *) Add a new function PKCS7_signatureVerify. This allows the verification + of a PKCS#7 signature but with the signing certificate passed to the + function itself. This contrasts with PKCS7_dataVerify which assumes the + certificate is present in the PKCS#7 structure. This isn't always the + case: certificates can be omitted from a PKCS#7 structure and be + distributed by "out of band" means (such as a certificate database). + [Steve Henson] + + *) Complete the PEM_* macros with DECLARE_PEM versions to replace the + function prototypes in pem.h, also change util/mkdef.pl to add the + necessary function names. + [Steve Henson] + + *) mk1mf.pl (used by Windows builds) did not properly read the + options set by Configure in the top level Makefile, and Configure + was not even able to write more than one option correctly. + Fixed, now "no-idea no-rc5 -DCRYPTO_MDEBUG" etc. works as intended. + [Bodo Moeller] + + *) New functions CONF_load_bio() and CONF_load_fp() to allow a config + file to be loaded from a BIO or FILE pointer. The BIO version will + for example allow memory BIOs to contain config info. + [Steve Henson] *) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS.
