Symmetric Key Length Specification
struct KeyLengthSpecification;
Represents the length requirements on an algorithm key
this(size_t keylen);
- Parameters
size_t keylen the supported key length
Constructor for fixed length keys
this(size_t min_k, size_t max_k, size_t k_mod = 1);
- Parameters
size_t min_k the smallest supported key length size_t max_k the largest supported key length size_t k_mod the number of bytes the key must be a multiple of
Constructor for variable length keys
const bool validKeylength(size_t length);
- Parameters
size_t length is a key length in bytes - Returns
- true iff this length is a valid length for this algo
const size_t minimumKeylength();
- Returns
- minimum key length in bytes
const size_t maximumKeylength();
- Returns
- maximum key length in bytes
const size_t keylengthMultiple();
- Returns
- key length multiple in bytes
