const type: desState

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

const func integer: blockSize (DES)

Block size used by the DES (Data Encryption Standard) block cipher.

Returns:

the block size used by the DES cipher.

const func desState: setDesKey (in string: desKey, in string: initializationVector)

Set key and initialization vector for the DES (Data Encryption Standard) block cipher.

Parameters:

desKey - The key to be used for DES.

initializationVector - The initialisation vector (IV) for DES.

Returns:

the DES cipher state.

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

Set key and initialization vector for the DES (Data Encryption Standard) block cipher.

Parameters:

cipherKey - The key to be used for DES.

initializationVector - The initialisation vector (IV) for DES.

Returns:

the initial cipherState of a DES cipher.

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

Encode a string with the DES (Data Encryption Standard) block cipher.

Returns:

the encoded string.

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

Decode a string with the DES (Data Encryption Standard) block cipher.

Returns:

the decoded string.
