- * Use:                Returns a sensible key size.  If @sz@ is nonzero, it is
- *             interpreted as an amount (in bytes) of key material which the
- *             caller has available, and the return value is either the
- *             largest allowable key size less than or equal to the caller's
- *             size, or zero if there is no valid key length small enough.
- *             If @sz@ is zero, the function returns a `recommended' key
- *             size.
