This patchset changes akcipher api to support ECDSA style signature verification. Augments x509 parser to make it work with EC-RDSA certificates. And finally implements EC-RDSA (GOST 34.10) signature verification. It is intended to use in IMA for appraisal. Tested on x86_64 with openssl+gost-engine generated certificates.
