Hi Michel,
it looks like what I am looking for, but the software uses EVP_VerifyInit_ex
which is a typedef for EVP_DigestInit_ex. How are those functions related to
EVP_DigestVerifyInit? Can I use EVP_DigestVerify* functions along with
EVP_Verify* functions? I must not break compatibility with the old
implementation which needs to support arbitrary MD algorithms.
Thank you for your response!
