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. + [Steve Henson] + + *) Fixed a typo bug that would cause ENGINE_set_default() to set an + ENGINE as defaults for all supported algorithms irrespective of + the 'flags' parameter. 'flags' is now honoured, so applications + should make sure they are passing it correctly. + [Geoff Thorpe] + + *) Make sure the default DSA_METHOD implementation only uses its + dsa_mod_exp() and/or bn_mod_exp() handlers if they are non-NULL, + and change its own handlers to be NULL so as to remove unnecessary + indirection. This lets alternative implementations fallback to the + default implementation more easily. + [Geoff Thorpe] + + *) Support for directoryName in GeneralName related extensions + in config files. + [Steve Henson] *) Make it possible to link applications using Makefile.shared.
