EVP_DigestVerifyFinal function

@RecordUse.new() @Native<Int Function(Pointer<EVP_MD_CTX>, Pointer<Uint8>, Size)>(ffi.Pointer<EVP_MD_CTX>, ffi.Pointer<ffi.Uint8>, ffi.Size)>(symbol: 'bssl_dart_EVP_DigestVerifyFinal') int EVP_DigestVerifyFinal(Pointer<EVP_MD_CTX> ctx, Pointer<Uint8> sig, int sig_len)

EVP_DigestVerifyFinal verifies that sig_len bytes of sig are a valid signature for the data that has been included by one or more calls to EVP_DigestVerifyUpdate. It returns one on success and zero otherwise.

This function performs streaming signature verification and will fail for signature algorithms which do not support this. Use EVP_DigestVerify for a single-shot verification.
