I've succsessuflly implemented GOST 28147-89 symmetric transform. You can see
alpha version of a patch.
I think i will add cfb suffix to all transform names, as gost98 works by default
in cfb mode. And this mode is recommended. (cbc even has only custom
implementation as it is out of standard)
I also met an issue I'd like to discuss...
cfb mode do not need padding. And for AES and DES encryption some strange
efforts are made in openssl/ciphers.c in functions
So I've wrapped all padding code in
if ((xmlSecKeyDataId*) ctx->keyId != (xmlSecKeyDataId*)
and everything work well now.
I am not sure that it is the best way to do the trick...
If this way is good enough I will indent code in proper way there. If not,
tell me what way to use...
