Series [v7,01/11] ima-evm-utils: Convert read_pub_key to EVP_PKEY API | expand

Commit Message

Vitaly Chikunov June 23, 2019, 9 a.m. UTC 
RSA_ASN1_templates[] are not needed anymore, because we switched to the
generic EVP_PKEY OpenSSL API to generate v2 signatures instead of
constructing PKCS1 ourselves.
