WebApr 27, 2024 · The principle that PKCS#5 uses for 64-bit blocks padding is easily generalized to block ciphers with larger blocks (up to 255 octets per block), and that's what PKCS#7 padding is: for a message of m octets ( 8 m bits) and a block cipher of k octets ( 8 k bits), pad the message with p = k − ( m mod k) octets with value p.
