Symmetric Algorithm Base Class
interface SymmetricAlgorithm;
This class represents a symmetric algorithm object.
final const size_t maximumKeylength();
- Returns
- minimum allowed key length
final const size_t minimumKeylength();
- Returns
- maxmium allowed key length
final const bool validKeylength(size_t length);
- Parameters
size_t length the key length to be checked. - Returns
- true if the key length is valid.
Check whether a given key length is valid for this algorithm.
