SSL3 (GNU cryptographic primitives and tools, version 2.1.0)

Class SSL3

public class SSL3 extends BasePad

The padding scheme used by the Secure Sockets Layer, version 3. This padding scheme is used in the block-ciphered struct, e.g.:

 block-ciphered struct {
   opaque content[SSLCompressed.length];
   opaque MAC[CipherSpec.hash_size];
   uint8 padding[GenericBlockCipher.padding_length];
   uint8 padding_length;
 } GenericBlockCipher;

Where padding_length is cipher_block_size - ((SSLCompressed.length + CipherSpec.hash_size) % cipher_block_size) - 1. That is, the padding is enough bytes to make the plaintext a multiple of the block size minus one, plus one additional byte for the padding length. The padding can be any arbitrary data.
