Indeed, NID_sha256 works great in my case, thank you! I will have a look at EVP_DigestSign*() functions too.

If you already have the hash you can use RSA_sign (though EVP_PKEY_sign() is preferred) the type parameter in the NID of the digest algorithm, for SHA256 you use NID_sha256. Steve. -- Dr Stephen N.

[openssl-users] RSA sign message
Hi, I need to RSA sign a message using SHA256 as hash and PKCS1 v1.5 as padding. I am however confused about the *type* parameter of RSA_sign function [0] What is the value that I should use for *type* in my particular case?
