Minimal complete definition

blockSize, ecbEncrypt, ecbDecrypt

Methods

blockSize :: cipher -> Int Source #

Return the size of block required for this block cipher

ecbEncrypt :: ByteArray ba => cipher -> ba -> ba Source #

Encrypt blocks

the input string need to be multiple of the block size

ecbDecrypt :: ByteArray ba => cipher -> ba -> ba Source #

Decrypt blocks

the input string need to be multiple of the block size

cbcEncrypt :: ByteArray ba => cipher -> IV cipher -> ba -> ba Source #

encrypt using the CBC mode.

input need to be a multiple of the blocksize

cbcDecrypt :: ByteArray ba => cipher -> IV cipher -> ba -> ba Source #

decrypt using the CBC mode.

input need to be a multiple of the blocksize

cfbEncrypt :: ByteArray ba => cipher -> IV cipher -> ba -> ba Source #

encrypt using the CFB mode.

input need to be a multiple of the blocksize

cfbDecrypt :: ByteArray ba => cipher -> IV cipher -> ba -> ba Source #

decrypt using the CFB mode.

input need to be a multiple of the blocksize

ctrCombine :: ByteArray ba => cipher -> IV cipher -> ba -> ba Source #

combine using the CTR mode.

CTR mode produce a stream of randomized data that is combined (by XOR operation) with the input stream.

encryption and decryption are the same operation.

input can be of any size

aeadInit :: ByteArrayAccess iv => AEADMode -> cipher -> iv -> CryptoFailable (AEAD cipher) Source #

Initialize a new AEAD State

When Nothing is returns, it means the mode is not handled.
