One requirement is to use PKCS#1 v2.1 for RSA functions. > Then you need to use EVP_PKEY_sign/EVP_PKEY_verify or EVP_DigestSign*/EVP_DigestVerify. In either case you have an EVP_PKEY_CTX structure and you need to set the padding mode and parameters using EVP_PKEY_CTX_set_rsa_padding(), EVP_PKEY_CTX_set_rsa_pss_saltlen() and if you use EVP_PKEY_sign/EVP_PKEY_verify EVP_PKEY_CTX_set_signature_md().
