                     12:  * This code is in the public domain; do with it what you wish.

                     14:  * Equivalent code is available from RSA Data Security, Inc.
                     15:  * This code has been tested against that, and is equivalent,
                     16:  * except that you don't need to include two pages of legalese
                     17:  * with every copy.
