Specification

The CipherSuite class currently lacks implementations for the following authentication and integrity algorithms:

Authentication Algorithms:

• RAKP HMAC SHA-256
• RAKP HMAC MD5

Integrity Algorithms:

• HMAC SHA-256-128
• HMAC MD5-128
• MD5-128

These algorithms are referenced in the class but have not been implemented yet. Their implementations must be added and validated through testing.
