const type: aesState

cipherState implementation type describing the state of an AES cipher. The data is encrypted / decrypted with the AES (Advanced encryption standard) block cipher.

const func integer: blockSize (AES)

Block size used by the AES (Advanced Encryption Standard) block cipher.

Returns:

the block size used by the AES cipher.

const func aesState: setAesKey (in string: aesKey, in string: initializationVector)

Set key and initialization vector for the AES (Advanced Encryption Standard) block cipher.

Parameters:

aesKey - The key to be used for AES.

initializationVector - The initialisation vector (IV) for AES.

Returns:

the AES (Advanced Encryption Standard) cipher state.

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

Set key and initialization vector for the AES (Advanced Encryption Standard) block cipher.

Parameters:

cipherKey - The key to be used for AES.

initializationVector - The initialisation vector (IV) for AES.

Returns:

the initial cipherState of a AES cipher.

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

Encode a string with the AES (Advanced Encryption Standard) block cipher.

Returns:

the encoded string.

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

Decode a string with the AES (Advanced Encryption Standard) block cipher.

Returns:

the decoded string.
