What are Cipher Suites?
Cipher suites are combinations of cryptographic algorithms used to establish secure connections. They determine encryption strength, key exchange methods, and message authentication. Modern cipher suites use AEAD (Authenticated Encryption with Associated Data) for optimal security and performance.
What this analysis covers
- Supported cipher suites and their strength
- Perfect Forward Secrecy (PFS) validation
- Weak or deprecated cipher detection
- TLS version compatibility and preferences
- Key exchange algorithm analysis
- Encryption algorithm strength assessment
Modern Security Standards
- Preferred: TLS_AES_256_GCM_SHA384, TLS_AES_128_GCM_SHA256
- Acceptable: TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
- Avoid: RC4, 3DES, CBC mode without proper padding
- Deprecated: MD5, SHA-1 (except for HMAC in TLS 1.2)
Perfect Forward Secrecy (PFS)
PFS ensures that past communications remain secure even if long-term private keys are compromised. Look for ECDHE (Elliptic Curve Diffie-Hellman Ephemeral) or DHE (Diffie-Hellman Ephemeral) in your cipher suite names to ensure PFS is enabled.
Cipher Suite Optimization
- Prioritize AEAD ciphers (AES-GCM, ChaCha20-Poly1305)
- Enable ECDHE for Perfect Forward Secrecy
- Disable weak ciphers (RC4, 3DES, CBC without proper padding)
- Use strong key exchange algorithms (ECDHE, DHE)
- Configure cipher suite order by strength
Tool-specific questions
What's the difference between AES-128 and AES-256?
Should I disable all CBC ciphers?
What are AEAD ciphers?
How often should I review cipher suite configuration?
Can I use different cipher suites for different TLS versions?
