Member Function Documentation

size_t Skinny128_256_Tweaked::keySize ( ) const

virtual

Size of a Skinny128_256_Tweaked key in bytes.

Implements BlockCipher.

Definition at line 1382 of file Skinny128.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.

Implements BlockCipher.
