Previously, ERR_reason_error_string() returned + library names as reason strings for SYSerr; but SYSerr is a special + case where small numbers are errno values, not library numbers. + [Bodo Moeller] + + *) Add '-dsaparam' option to 'openssl dhparam' application. This + converts DSA parameters into DH parameters. (When creating parameters, + DSA_generate_parameters is used.) + [Bodo Moeller] + + *) Include 'length' (recommended exponent length) in C code generated + by 'openssl dhparam -C'. + [Bodo Moeller] + + *) The second argument to set_label in perlasm was already being used + so couldn't be used as a "file scope" flag. Moved to third argument + which was free. + [Steve Henson] + + *) In PEM_ASN1_write_bio and some other functions, use RAND_pseudo_bytes + instead of RAND_bytes for encryption IVs and salts. + [Bodo Moeller] + + *) Include RAND_status() into RAND_METHOD instead of implementing + it only for md_rand.c Otherwise replacing the PRNG by calling + RAND_set_rand_method would be impossible. + [Bodo Moeller] + + *) Don't let DSA_generate_key() enter an infinite loop if the random + number generation fails. + [Bodo Moeller] + + *) New 'rand' application for creating pseudo-random output. + [Bodo Moeller] + + *) Added configuration support for Linux/IA64 + [Rolf Haberrecker ] + + *) Assembler module support for Mingw32. + [Ulf Möller] + + *) Shared library support for HPUX (in shlib/). + [Lutz Jaenicke and Anonymous] + + *) Shared library support for Solaris gcc. + [Lutz Behnke ] + + Changes between 0.9.4 and 0.9.5 [28 Feb 2000] + + *) PKCS7_encrypt() was adding text MIME headers twice because they + were added manually and by SMIME_crlf_copy(). + [Steve Henson] + + *) In bntest.c don't call BN_rand with zero bits argument. + [Steve Henson, pointed out by Andrew W. Gray ] + + *) BN_mul bugfix: In bn_mul_part_recursion() only the a>a[n] && b>b[n] + case was implemented. This caused BN_div_recp() to fail occasionally. + [Ulf Möller] + + *) Add an optional second argument to the set_label() in the perl + assembly language builder. If this argument exists and is set + to 1 it signals that the assembler should use a symbol whose + scope is the entire file, not just the current function. This + is needed with MASM which uses the format label:: for this scope. + [Steve Henson, pointed out by Peter Runestig ] + + *) Change the ASN1 types so they are typedefs by default. Before + almost all types were #define'd to ASN1_STRING which was causing + STACK_OF() problems: you couldn't declare STACK_OF(ASN1_UTF8STRING) + for example. + [Steve Henson] + + *) Change names of new functions to the new get1/get0 naming + convention: After 'get1', the caller owns a reference count + and has to call ..._free; 'get0' returns a pointer to some + data structure without incrementing reference counters. + (Some of the existing 'get' functions increment a reference + counter, some don't.) + Similarly, 'set1' and 'add1' functions increase reference + counters or duplicate objects. + [Steve Henson] + + *) Allow for the possibility of temp RSA key generation failure: + the code used to assume it always worked and crashed on failure. + [Steve Henson] + + *) Fix potential buffer overrun problem in BIO_printf(). + [Ulf Möller, using public domain code by Patrick Powell; problem + pointed out by David Sacerdote ] + + *) Support EGD . New functions + RAND_egd() and RAND_status(). In the command line application, + the EGD socket can be specified like a seed file using RANDFILE + or -rand. + [Ulf Möller] + + *) Allow the string CERTIFICATE to be tolerated in PKCS#7 structures. + Some CAs (e.g. Verisign) distribute certificates in this form. + [Steve Henson] + + *) Remove the SSL_ALLOW_ADH compile option and set the default cipher + list to exclude them. This means that no special compilation option + is needed to use anonymous DH: it just needs to be included in the + cipher list. + [Steve Henson] + + *) Change the EVP_MD_CTX_type macro so its meaning consistent with + EVP_MD_type. The old functionality is available in a new macro called + EVP_MD_md(). Change code that uses it and update docs. + [Steve Henson] + + *) ..._ctrl functions now have corresponding ..._callback_ctrl functions + where the 'void *' argument is replaced by a function pointer argument. + Previously 'void *' was abused to point to functions, which works on + many platforms, but is not correct. As these functions are usually + called by macros defined in OpenSSL header files, most source code + should work without changes. + [Richard Levitte] + + *) (which is created by Configure) now contains + sections with information on -D... compiler switches used for + compiling the library so that applications can see them. To enable + one of these sections, a pre-processor symbol OPENSSL_..._DEFINES + must be defined. E.g., + #define OPENSSL_ALGORITHM_DEFINES + #include + defines all pertinent NO_ symbols, such as NO_IDEA, NO_RSA, etc. + [Richard Levitte, Ulf and Bodo Möller] + + *) Bugfix: Tolerate fragmentation and interleaving in the SSL 3/TLS + record layer. + [Bodo Moeller] + + *) Change the 'other' type in certificate aux info to a STACK_OF + X509_ALGOR. Although not an AlgorithmIdentifier as such it has + the required ASN1 format: arbitrary types determined by an OID. + [Steve Henson] + + *) Add some PEM_write_X509_REQ_NEW() functions and a command line + argument to 'req'. This is not because the function is newer or + better than others it just uses the work 'NEW' in the certificate + request header lines. Some software needs this. + [Steve Henson] + + *) Reorganise password command line arguments: now passwords can be + obtained from various sources. Delete the PEM_cb function and make + it the default behaviour: i.e. if the callback is NULL and the + usrdata argument is not NULL interpret it as a null terminated pass + phrase. If usrdata and the callback are NULL then the pass phrase + is prompted for as usual. + [Steve Henson] + + *) Add support for the Compaq Atalla crypto accelerator. If it is installed, + the support is automatically enabled. The resulting binaries will + autodetect the card and use it if present. + [Ben Laurie and Compaq Inc.] + + *) Work around for Netscape hang bug. This sends certificate request + and server done in one record. Since this is perfectly legal in the + SSL/TLS protocol it isn't a "bug" option and is on by default. See + the bugs/SSLv3 entry for more info. + [Steve Henson] + + *) HP-UX tune-up: new unified configs, HP C compiler bug workaround. + [Andy Polyakov] + + *) Add -rand argument to smime and pkcs12 applications and read/write + of seed file. + [Steve Henson] + + *) New 'passwd' tool for crypt(3) and apr1 password hashes. + [Bodo Moeller] + + *) Add command line password options to the remaining applications. + [Steve Henson] *) Bug fix for BN_div_recp() for numerators with an even number of bits. @@ -193,7 +371,9 @@ has a return value which indicates the quality of the random data (1 = ok, 0 = not seeded).
