13 * Types of ascii representations for keys.  "Standard" means a 64 bit
14 * hex number in NBS format, i.e. with the low order bit of each byte
15 * a parity bit.  "NTP" means a 64 bit key in NTP format, with the
16 * high order bit of each byte a parity bit.  "Ascii" means a 1-to-8
17 * character string whose ascii representation is used as the key.
