Mini Shell

# A reasonable default for today's standards. It should provide
# 112-bit security with the exception of SHA1 signatures needed for DNSSec
# and other still prevalent legacy use of SHA1 signatures.

# MACs: all HMAC with SHA1 or better + all modern MACs (Poly1305 etc)
# Curves: all prime >= 255 bits (including Bernstein curves)
# Signature algorithms: with SHA-1 hash or better (no DSA)
# TLS Ciphers: >= 128-bit key, >= 128-bit block (AES, ChaCha20, including AES-CBC)
# non-TLS Ciphers: as TLS Ciphers with added Camellia
# key exchange: ECDHE, RSA, DHE (no DHE-DSS)
# DH params size: >= 2048
# RSA params size: >= 2048
# TLS protocols: TLS >= 1.2, DTLS >= 1.2
