# Class SSL.Cipher.CipherSpec

Description

  Cipher specification.

Variable bulk_cipher_algorithm

  ``program` SSL.Cipher.CipherSpec.bulk_cipher_algorithm`

Description

  The algorithm to use for the bulk of the transfered data.

Variable hash_size

  ``int` SSL.Cipher.CipherSpec.hash_size`

Description

  The number of bytes in the MAC hashes.

Variable iv_size

  ``int` SSL.Cipher.CipherSpec.iv_size`

Description

  The number of bytes of random data needed for initialization vectors.

Variable key_bits

  ``int` SSL.Cipher.CipherSpec.key_bits`

Description

  The effective number of bits in key_material.

  This is typically `key_material * 8`, but for eg DES this is `key_material * 7`.

Variable key_material

  ``int` SSL.Cipher.CipherSpec.key_material`

Description

  The number of bytes of key material used on initialization.

Variable mac_algorithm

  ``program` SSL.Cipher.CipherSpec.mac_algorithm`

Description

  The Message Authentication Code to use for the packets.

Variable sign

  ``function`(`object`, `string`, `ADT.struct`:`ADT.struct`) SSL.Cipher.CipherSpec.sign`

Description

  The function used to sign packets.

Variable verify

  ``function`(`object`, `string`, `ADT.struct`, `Gmp.mpz`:`bool`) SSL.Cipher.CipherSpec.verify`

Description

  The function used to verify the signature for packets.
