- Changes between 0.9.4 and 0.9.5 [xx XXX 2000]
+ Changes between 0.9.5 and 0.9.5a [XX XXX 2000]
+
+ *) For SSL_[CTX_]set_tmp_dh, don't create a DH key if SSL_OP_SINGLE_DH_USE
+ is set; it will be thrown away anyway because each handshake creates
+ its own key.
+ ssl_cert_dup, which is used by SSL_new, now copies DH keys in addition
+ to parameters -- in previous versions (since OpenSSL 0.9.3) the
+ 'default key' from SSL_CTX_set_tmp_dh would always be lost, meanining
+ you effectivly got SSL_OP_SINGLE_DH_USE when using this macro.
+ [Bodo Moeller]
+
+ *) New s_client option -ign_eof: EOF at stdin is ignored, and
+ 'Q' and 'R' lose their special meanings (quit/renegotiate).
+ This is part of what -quiet does; unlike -quiet, -ign_eof
+ does not suppress any output.
+ [Richard Levitte]
+
+ *) Add compatibility options to the purpose and trust code. The
+ purpose X509_PURPOSE_ANY is "any purpose" which automatically
+ accepts a certificate or CA, this was the previous behaviour,
+ with all the associated security issues.
+
+ X509_TRUST_COMPAT is the old trust behaviour: only and
+ automatically trust self signed roots in certificate store. A
+ new trust setting X509_TRUST_DEFAULT is used to specify that
+ a purpose has no associated trust setting and it should instead
+ use the value in the default purpose.
+ [Steve Henson]
+
+ *) Fix the PKCS#8 DSA private key code so it decodes keys again
+ and fix a memory leak.
+ [Steve Henson]
+
+ *) In util/mkerr.pl (which implements 'make errors'), preserve
+ reason strings from the previous version of the .c file, as
+ the default to have only downcase letters (and digits) in
+ automatically generated reasons codes is not always appropriate.
+ [Bodo Moeller]
+
+ *) In ERR_load_ERR_strings(), build an ERR_LIB_SYS error reason table
+ using strerror. 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 <rolf@suse.de>]
+
+ *) Assembler module support for Mingw32.
+ [Ulf Möller]
+
+ *) Shared library support for HPUX (in shlib/).
+ [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE> and Anonymous]
+
+ *) Shared library support for Solaris gcc.
+ [Lutz Behnke <behnke@trustcenter.de>]
+
+ 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 <agray@iconsinc.com>]
+
+ *) 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 <peter@runestig.com>]
+
+ *) 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 <das33@cornell.edu>]
+
+ *) Support EGD <http://www.lothar.com/tech/crypto/>. 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]
+
+ *) <openssl/opensslconf.h> (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 <openssl/opensslconf.h>
+ defines all pertinent NO_<algo> 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
has a return value which indicates the quality of the random data
(1 = ok, 0 = not seeded). Also an error is recorded on the thread's
error queue. New function RAND_pseudo_bytes() generates output that is
- guaranteed to be unique but not unpredictable.
+ guaranteed to be unique but not unpredictable. RAND_add is like
+ RAND_seed, but takes an extra argument for an entropy estimate
+ (RAND_seed always assumes full entropy).
[Ulf Möller]
*) Do more iterations of Rabin-Miller probable prime test (specifically,
*) Rewrite ssl3_read_n (ssl/s3_pkt.c) avoiding a couple of bugs.
[Bodo Moeller]
- *) New function X509_CTX_rget_chain(), this returns the chain
+ *) New function X509_CTX_rget_chain() (renamed to X509_CTX_get1_chain
+ in the 0.9.5 release), this returns the chain
from an X509_CTX structure with a dup of the stack and all
the X509 reference counts upped: so the stack will exist
after X509_CTX_cleanup() has been called. Modify pkcs12.c
To get OpenSSL to support MS SGC we have to permit a second client
hello message after we have sent server done. In addition we have to
- reset the MAC if we do get this second client hello and include the
- data just received.
+ reset the MAC if we do get this second client hello.
[Steve Henson]
*) Add a function 'd2i_AutoPrivateKey()' this will automatically decide
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).
+ Also rename the EVP_PKEY_get_*() to EVP_PKEY_rget_*()
+ (renamed to EVP_PKEY_get1_*() in the OpenSSL 0.9.5 release) and add
+ EVP_PKEY_rset_*() functions (renamed to EVP_PKEY_set1_*())
+ 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
projects / openssl.git / blobdiff
