WebMar 6, 2016 · PKCS#7 compatible padding can range from 1 to 16 bytes for block ciphers such as AES. If your plaintext always happens to be n ∗ 16 + 15 bytes in size then your padding would consist of a single byte. A single byte is never enough to guarantee integrity of the plaintext. Padding isn't a checksum. WebTriple DES or DESede, a symmetric-key algorithm for the encryption of electronic data, is the successor of DES(Data Encryption Standard) and provides more secure encryption then DES. The Triple DES breaks the user-provided key into three subkeys as k1, k2, and k3.
