And if so, Are there a way to fix my code in order to encode and
decode messages with ECDSA algorithm?
I made a sample source code to explain my problem:
https://gist.github.com/babelouest/ad6ca39e43587bf037b9868e1ac9ad9d
This program signs and then verify the signature of a message using
SHA256 and ECDSA algorithms.
- When using GnuTLS 2.5.8, signing and verifying the message work fine.
- When using GnuTLS 3.6.5, signing works, but verifying the message
fails.
If I use r and s structures with
gnutls_decode_rs_value/gnutls_encode_rs_value, the result is the same. I
can't figure out what's wrong with my code.
Does someone have an idea?
