3.1.3 TESTOUT LAB CODE
3.1.3 TESTOUT LAB GENERATOR
For a stream cipher implementation to remain secure, its pseudorandom generator should be unpredictable and the key should never be reused. It uses an infinite stream of pseudorandom bits as the key. DES, Triple DES, AES, IDEA, and Blowfish.Įncrypt 1 bit or byte of plaintext at a time.
3.1.3 TESTOUT LAB 64 BITS
A 64-bit block cipher will take in 64 bits of plaintext and encrypt it into 64 bits of ciphertext. The usual sizes of each block are 64 bits, 128 bits, and 256 bits.
