class crandas.crypto.cipher.Cipher(name, round_keys)¶

Bases: object

Cipher object, contains the round keys needed for encryption of a message using the encrypt method. Currently only AES-128, AES-192 and AES-256 are supported for 16 byte messages.

encrypt(message)¶

Encrypt the message given the round keys of the Cipher object

Parameters:: message (Bytestring) – Message to be encrypted, currently must be 16 bytes
Returns:: Message encrypted with the key belonging to the Cipher
Return type:: Bytestring
