Cryptographic Algorithm Selection and Post-Quantum Readiness
Reference for which cryptographic algorithms to use, which to avoid, and how to prepare for post-quantum cryptography.
Banned (Insecure) Algorithms
NEVER use these algorithms. They are cryptographically broken.
| Type | Banned |
|---|---|
| Hash | MD2, MD4, MD5, SHA-0 |
| Symmetric | RC2, RC4, Blowfish, DES, 3DES |
| Key Exchange | Static RSA, Anonymous Diffie-Hellman |
Deprecated (Legacy/Weak) Algorithms
Avoid in new designs. Prioritize migration away from these.
