TLS1 (GNU cryptographic primitives and tools, version 2.1.0)

Class TLS1

public class TLS1 extends BasePad

The padding scheme used by the Transport Layer Security protocol, version 1. This padding scheme is used in the block-ciphered struct, e.g.:

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

Where padding_length is any multiple of cipher_block_size - ((SSLCompressed.length + CipherSpec.hash_size) % cipher_block_size) - 1 that is less than 255. Every byte of the padding must be equal to padding_length. That is, the end of the plaintext is n + 1 copies of the unsigned byte n.
