It uses a block size of 128 bits and can have key sizes up to 256 bits, making it highly secure. Twofish was one of the five finalists in the Advanced Encrypt
Question
This form of encryption algorithm is a symmetric key block cipher that is characterized by a 128- bit block size, and its key size can be up to 256 bits. Which among the following is this encryption algorithm?
Options
- AHMAC encryption algorithm
- BTwofish encryption algorithm
- CIDEA
- DBlowfish encryption algorithm
Explanation
The Twofish encryption algorithm is a symmetric key block cipher that was designed to be secure, efficient, and flexible. It uses a block size of 128 bits and can have key sizes up to 256 bits, making it highly secure. Twofish was one of the five finalists in the Advanced Encryption Standard (AES) competition organized by the U.S. National Institute of Standards and Technology (NIST) in 1997. Although it was not selected as the winner, Twofish is still considered a highly secure encryption algorithm and is widely used in various applications.
