Types
aesState
cipherState implementation type describing the state of an AES cipher.

aesState

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.


Function Summary
integer
blockSize (AES)
Block size used by the AES (Advanced Encryption Standard) block cipher.
aesState
setAesKey (in string: aesKey, in string: initializationVector)
Set key and initialization vector for the AES (Advanced Encryption Standard) block cipher.
cipherState
setCipherKey (AES, in string: cipherKey, in string: initializationVector)
Set key and initialization vector for the AES (Advanced Encryption Standard) block cipher.
string
encode (inout aesState: state, in string: plaintext)
Encode a string with the AES (Advanced Encryption Standard) block cipher.
string
decode (inout aesState: state, in string: encoded)
Decode a string with the AES (Advanced Encryption Standard) block cipher.
