WebJan 17, 2024 · Twofish Encryption Algorithm. This form of the encryption algorithm is a symmetric key block cipher which is characterized by 128-bit block size and whose keys’ size can run up to 256 bits. This protocol uses one key for encryption and decryption. It is a fast and flexible standard for eight-bit and thirty two-bit CPUs, and small smart cards. http://seminar.uny.ac.id/icriems/sites/seminar.uny.ac.id.icriems/files/prosiding2024/SE02_AKIK.pdf
