Deprecated Algorithm Warning
- • DES - Key length too short (56 bits), vulnerable to brute force
- • 3DES - More secure but slow, recommend migrating to AES
- • MD5 - Collision attacks exist, should not be used for security
- • SHA-1 - Collisions discovered, should migrate for signatures
- • RC4 - Bias attacks exist, now prohibited
