Detailed explanation-1: -Which of the following is not a type of symmetric-key cryptography technique? Explanation: Diffie hellman cipher is not a type of symmetric-key cryptography technique. All other mentioned are a type of symmetric-key cryptography technique.
Detailed explanation-2: -RSA is a type of asymmetric encryption, which uses two different but linked keys. In RSA cryptography, both the public and the private keys can encrypt a message. The opposite key from the one used to encrypt a message is used to decrypt it.
Detailed explanation-3: -RSA is an algorithm used by systems to encrypt and decrypt messages. It is an asymmetric cryptographic algorithm. Asymmetric means that there are two different keys.
Detailed explanation-4: -Examples of symmetric ciphers are Advanced Encryption Standard (AES), Data Encryption Standard (DES), Blowfish, and International Data Encryption Algorithm (IDEA).
