# Test interop with OpenSSL and GnuTLS (and self-op while at it).
#
# Check each common ciphersuite, with each version, both ways (client/server),
# with and without client authentication.
#
# Peer version requirements:
# - OpenSSL 1.0.1e 11 Feb 2013 (probably NOT since 1.0.1, tested with 1.0.1e)
# - GnuTLS 3.2.15 (probably works since 3.2.12 but tested only with 3.2.15)
