SSCP · Question #652
The Diffie-Hellman algorithm is used for:
The correct answer is C. Key agreement. The Diffie-Hellman algorithm is used for Key agreement (key distribution) and cannot be used to encrypt and decrypt messages. Note: key agreement, is different from key exchange, the functionality used by the other asymmetric algorithms.
