The (pre-generated) prime + table crypto/bn/bn_prime.h was already correct, but it could not be + re-generated on some platforms because of the "division by zero" + situation in the script. + [Ralf S. Engelschall] + + *) Update support for ECC-based TLS ciphersuites according to + draft-ietf-tls-ecc-03.txt: the KDF1 key derivation function with + SHA-1 now is only used for "small" curves (where the + representation of a field element takes up to 24 bytes); for + larger curves, the field element resulting from ECDH is directly + used as premaster secret. + [Douglas Stebila (Sun Microsystems Laboratories)] + + *) Add code for kP+lQ timings to crypto/ec/ectest.c, and add SEC2 + curve secp160r1 to the tests. + [Douglas Stebila (Sun Microsystems Laboratories)] + + *) Add the possibility to load symbols globally with DSO. + [Götz Babin-Ebell via Richard Levitte] + + *) Add the functions ERR_set_mark() and ERR_pop_to_mark() for better + control of the error stack. + [Richard Levitte] + + *) Add support for STORE in ENGINE. + [Richard Levitte] + + *) Add the STORE type. The intention is to provide a common interface + to certificate and key stores, be they simple file-based stores, or + HSM-type store, or LDAP stores, or... + NOTE: The code is currently UNTESTED and isn't really used anywhere. + [Richard Levitte] + + *) Add a generic structure called OPENSSL_ITEM. This can be used to + pass a list of arguments to any function as well as provide a way + for a function to pass data back to the caller. + [Richard Levitte] + + *) Add the functions BUF_strndup() and BUF_memdup(). BUF_strndup() + works like BUF_strdup() but can be used to duplicate a portion of + a string. The copy gets NUL-terminated. BUF_memdup() duplicates + a memory area. + [Richard Levitte] + + *) Add the function sk_find_ex() which works like sk_find(), but will + return an index to an element even if an exact match couldn't be + found. The index is guaranteed to point at the element where the + searched-for key would be inserted to preserve sorting order. + [Richard Levitte] + + *) Add the function OBJ_bsearch_ex() which works like OBJ_bsearch() but + takes an extra flags argument for optional functionality. Currently, + the following flags are defined: + + OBJ_BSEARCH_VALUE_ON_NOMATCH + This one gets OBJ_bsearch_ex() to return a pointer to the first + element where the comparing function returns a negative or zero + number. + + OBJ_BSEARCH_FIRST_VALUE_ON_MATCH + This one gets OBJ_bsearch_ex() to return a pointer to the first + element where the comparing function returns zero. This is useful + if there are more than one element where the comparing function + returns zero. + [Richard Levitte] + + *) Make it possible to create self-signed certificates with 'openssl ca' + in such a way that the self-signed certificate becomes part of the + CA database and uses the same mechanisms for serial number generation + as all other certificate signing. The new flag '-selfsign' enables + this functionality. Adapt CA.sh and CA.pl.in. + [Richard Levitte] + + *) Add functionality to check the public key of a certificate request + against a given private. This is useful to check that a certificate + request can be signed by that key (self-signing). + [Richard Levitte] + + *) Make it possible to have multiple active certificates with the same + subject in the CA index file. This is done only if the keyword + 'unique_subject' is set to 'no' in the main CA section (default + if 'CA_default') of the configuration file. The value is saved + with the database itself in a separate index attribute file, + named like the index file with '.attr' appended to the name. + [Richard Levitte] + + *) Generate muti valued AVAs using '+' notation in config files for + req and dirName. + [Steve Henson] + + *) Support for nameConstraints certificate extension. + [Steve Henson] + + *) Support for policyConstraints certificate extension. + [Steve Henson] *) Support for policyMappings certificate extension.
