[RFC PATCH 0/4] crypto: Add EC-RDSA algorithm

From: Vitaly Chikunov
Date: Sun Jan 06 2019 - 08:36:28 EST


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.

Vitaly Chikunov (4):
X.509: Parse public key parameters from x509 for akcipher
akcipher: Introduce verify2 for public key algorithms
KEYS: set correct flags for keyctl if encrypt is not supported
crypto: Add EC-RDSA algorithm
