key ASN1 handling through a single EVP_PKEY_ASN1_METHOD structure and move
the spaghetti algorithm specific code to a single ASN1 module for each
algorithm.
See crypto/engine/README for details.
- it also removes openbsd_hw.c from the build (that functionality is
going to be available in the openbsd ENGINE in a upcoming commit)
- evp_test has had the extra initialisation added so it will use (if
possible) any ENGINEs supporting the algorithms required.
sure they are available in opensslconf.h, by giving them names starting
with "OPENSSL_" to avoid conflicts with other packages and by making
sure e_os2.h will cover all platform-specific cases together with
opensslconf.h.
I've checked fairly well that nothing breaks with this (apart from
external software that will adapt if they have used something like
NO_KRB5), but I can't guarantee it completely, so a review of this
change would be a good thing.
Change EVP_SealInit() and EVP_OpenInit() to
handle cipher parameters.
Make it possible to set RC2 and RC5 params.
Make RC2 ASN1 code use the effective key bits
and not the key length.
TODO: document how new API works.
enhance and tidy up the EVP interface.
This patch adds initial support for variable length ciphers
and changes S/MIME code to use this.
Some other library functions need modifying to support use
of modified cipher parameters.
Also need to change all the cipher functions that should
return error codes, but currenly don't.
And of course it needs extensive testing...
find the right RecipientInfo based on the recipient certificate (so would
fail a lot of the time) and fixup cipher structures to correctly (maybe)
modify the AlgorithmIdentifiers. Largely untested at present... this will be
fixed in due course. Well the stuff was broken to begin with so if its broken
now then you haven't lost anything :-)
script, translates function codes better and doesn't need the K&R function
prototypes to work (NB. the K&R prototypes can't be wiped just yet: they are
still needed by the DEF generator...). I also ran the script with the -rewrite
option to update all the header and source files.
