const type: tdesState

cipherState implementation type describing the state of a TDES cipher. The data is encrypted / decrypted with the TDES (Triple DES) block cipher.

const func integer: blockSize (TDES)

Block size used by the TDES (Triple DES) block cipher.

Returns:

the block size used by the TDES cipher.

const func tdesState: setTdesKey (in string: desKey, in string: initializationVector)

Set key and initialization vector for the TDES (Triple DES) block cipher.

Parameters:

desKey - The key to be used for TDES.

initializationVector - The initialisation vector (IV) for TDES.

Returns:

the TDES (Triple DES) cipher state.

const func cipherState: setCipherKey (TDES, in string: cipherKey, in string: initializationVector)

Set key and initialization vector for the TDES (Triple DES) block cipher.

Parameters:

cipherKey - The key to be used for TDES.

initializationVector - The initialisation vector (IV) for TDES.

Returns:

the initial cipherState of a TDES cipher.

const func string: encode (inout tdesState: state, in string: plaintext)

Encode a string with the TDES (Triple DES) block cipher.

Returns:

the encoded string.

const func string: decode (inout tdesState: state, in string: encoded)

Decode a string with the TDES (Triple DES) block cipher.

Returns:

the decoded string.
