Detailed Description

SKINNY block cipher with a 64-bit block and a 64-bit key.

Definition at line 71 of file Skinny64.h.

Member Function Documentation

size_t Skinny64_64::keySize ( ) const

virtual

Size of a Skinny64_64 key in bytes.

Implements BlockCipher.

Definition at line 1121 of file Skinny64.cpp.

virtual

Sets the key to use for future encryption and decryption operations.

Parameters

key	The key to use.
len	The length of the key.

Returns: Returns false if the key length is not supported, or the key is somehow "weak" and unusable by this cipher.

Use clear() or the destructor to remove the key and any other sensitive data from the object once encryption or decryption is complete.
