Provides a valid key length for the cipher.
keylength | the size of the key, in bytes |
keylength is provided in bytes, not bits. 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 If keylength is a multiple of KEYLENGTH_MULTIPLE, then keylength is returned. Otherwise, the function returns a lower multiple of KEYLENGTH_MULTIPLE.

The default IV requirements for the cipher.
The default value is NOT_RESYNCHRONIZABLE. See IV_Requirement in cryptlib.h for allowed values.
