class VariableKeyLength< D, N, M, Q, IV_REQ, IV_L >

Inherited by keyed algorithms with variable key length.

Template Parameters

D	Default key length, in bytes
N	Minimum key length, in bytes
M	Maximum key length, in bytes
Q	Default key length multiple, in bytes. The default multiple is 1.
IV_REQ	the IV requirements

inline

The minimum key length used by the algorithm provided as a constant.

MIN_KEYLENGTH is provided in bytes, not bits The maximum key length used by the algorithm provided as a constant

MAX_KEYLENGTH is provided in bytes, not bits The default key length used by the algorithm provided as a constant

DEFAULT_KEYLENGTH is provided in bytes, not bits The key length multiple used by the algorithm provided as a constant

MAX_KEYLENGTH is provided in bytes, not bits The default IV requirements for the algorithm provided as a constant

The default value is NOT_RESYNCHRONIZABLE. See IV_Requirement in cryptlib.h for allowed values. The default initialization vector length for the algorithm provided as a constant

IV_LENGTH is provided in bytes, not bits. The default implementation uses 0. Provides a valid key length for the algorithm provided by a static function.

Parameters

keylength the size of the key, in bytes

If keylength is less than MIN_KEYLENGTH, then the function returns MIN_KEYLENGTH. If keylength is greater than MAX_KEYLENGTH, then the function returns MAX_KEYLENGTH. If keylength is a multiple of KEYLENGTH_MULTIPLE, then keylength is returned. Otherwise, the function returns keylength rounded down to the next smaller multiple of KEYLENGTH_MULTIPLE.

keylength is provided in bytes, not bits.
