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!

Hi,

Isn’t it what you are looking for : EVP_PKEY_CTX_set_rsa_padding() ?
https://www.openssl.org/docs/manmaster/man3/EVP_PKEY_CTX_set_rsa_padding.html
and :
https://wiki.openssl.org/index.php/EVP_Signing_and_Verifying
(OpenSSL version >= 1.0)
Hope it helps,
Michel.
