# Only FIPS approved or allowed algorithms. It does not provide FIPS compliace
# by itself, the FIPS validated crypto modules must be properly installed
# and the machine must be booted into the FIPS mode.

# MACs: all HMAC with SHA1 or better
# Curves: all prime >= 256 bits
# Signature algorithms: with SHA224 hash or better (no DSA)
# TLS Ciphers: >= 128-bit key, >= 128-bit block (AES, including AES-CBC)
# non-TLS Ciphers: same
# key exchange: ECDHE, RSA, DHE (no DHE-DSS)
# DH params size: >= 2048
# RSA params size: >= 2048
# TLS protocols: TLS >= 1.2, DTLS >= 1.2
