Generation

# Block vs Stream Ciphers **Block ciphers** encrypt fixed-size chunks of plaintext (typically 64 or 128 bits) at a time, using the same key to transform each block through a substitution-permutation network. **Stream ciphers** encrypt data one bit or byte at a time by generating a continuous keystream that is XORed with the plaintext. **Key formula for stream ciphers:** *C = P ⊕ K* (encryption) and *P = C ⊕ K* (decryption) where C is ciphertext, P is plaintext, K is the keystream, and ⊕ represents XOR operation.
