- While checking if ciphersuite uses RSA key exchange methods,
the APIs `mbedtls_ssl_get_ciphersuite_id_from_ssl` and
`mbedtls_ssl_ciphersuite_from_id` were used to get the ciphersuite
info.
- However, this is incorrect as we need the ciphersuite info from the
handshake instance and not the ssl_session instance.
