The new API functions have "_ex" + postfixes and the older functions are reimplemented as wrappers for + the new ones. The OPENSSL_NO_DEPRECATED symbol can be used to hide + declarations of the old functions to help (graceful) attempts to + migrate to the new functions. Also, the new key-generation API + functions operate on a caller-supplied key-structure and return + success/failure rather than returning a key or NULL - this is to + help make "keygen" another member function of RSA_METHOD etc. + + Example for using the new callback interface: + + int (*my_callback)(int a, int b, BN_GENCB *cb) = ...; + void *my_arg = ...; + BN_GENCB my_cb; + + BN_GENCB_set(&my_cb, my_callback, my_arg); + + return BN_is_prime_ex(some_bignum, BN_prime_checks, NULL, &cb); + /* For the meaning of a, b in calls to my_callback(), see the + * documentation of the function that calls the callback. + * cb will point to my_cb; my_arg can be retrieved as cb->arg. + * my_callback should return 1 if it wants BN_is_prime_ex() + * to continue, or 0 to stop. + */ + + [Geoff Thorpe] + + *) Change the ZLIB compression method to be stateful, and make it + available to TLS with the number defined in + draft-ietf-tls-compression-04.txt. + [Richard Levitte] + + *) Add the ASN.1 structures and functions for CertificatePair, which + is defined as follows (according to X.509_4thEditionDraftV6.pdf): + + CertificatePair ::= SEQUENCE { + forward [0] Certificate OPTIONAL, + reverse [1] Certificate OPTIONAL, + -- at least one of the pair shall be present -- } + + Also implement the PEM functions to read and write certificate + pairs, and defined the PEM tag as "CERTIFICATE PAIR". + + This needed to be defined, mostly for the sake of the LDAP + attribute crossCertificatePair, but may prove useful elsewhere as + well. + [Richard Levitte] + + *) Make it possible to inhibit symlinking of shared libraries in + Makefile.shared, for Cygwin's sake. + [Richard Levitte] *) Extend the BIGNUM API by creating new macros that behave like functions @@ -313,7 +367,65 @@ TODO: bug: pad x with leading zeros if necessary EC_GROUP_get_nid() [Nils Larsch ] + + Changes between 0.9.6h and 0.9.7 [31 Dec 2002] + + *) Fix session ID handling in SSLv2 client code: the SERVER FINISHED + code (06) was taken as the first octet of the session ID and the last + octet was ignored consequently.
