  • Ticket #2018 – Description

    initial v5  
    772. Choose a number of padding bytes, {{{P}}}, evenly from {{{[0..X)}}} as determined by the encryption key. ''Note: this is important that the number is deterministic from the key, so that multiple encryptions of the same-keyed file will not pick different random numbers and allow an attacker to statistically observe the padding's size.''
    88
    9 3. Append {{{P}}} bytes of padding (0 bytes) to the ciphertext before encryption.
     93. Append {{{P}}} bytes of padding (0 bytes) to the plaintext before encryption. (This does not affect how the key is derived from the plaintext in the case of convergent encryption.)
