Which encryption method is also called the 2-key method?
A)Digital envelope
B)Asymmetric cryptography
C)Substitution cypher
D)Symmetric cryptography

Question

Quizplus · Accepted Answer

Asymmetric cryptography is also known as the 2-key method because it uses two different keys for encryption and decryption. One key is kept private and is known as the private key, while the other key is made public and is known as the public key. This method is used for secure communication over the internet and is widely used for secure online transactions. The other options, digital envelope and substitution cypher, are encryption methods but do not use the 2-key method, and symmetric cryptography uses only one key for encryption and decryption.
