-/*
- * This function implements the "bigcrypt" algorithm specifically for
- * Linux-PAM.
- *  
- * This algorithm is algorithm 0 (default) shipped with the C2 secure
- * implementation of Digital UNIX.
- * 
- * Disclaimer: This work is not based on the source code to Digital
- * UNIX, nor am I connected to Digital Equipment Corp, in any way
- * other than as a customer. This code is based on published
- * interfaces and reasonable guesswork.
- * 
- * Description: The cleartext is divided into blocks of SEGMENT_SIZE=8
- * characters or less. Each block is encrypted using the standard UNIX
- * libc crypt function. The result of the encryption for one block
- * provides the salt for the suceeding block.
- * 
- * Restrictions: The buffer used to hold the encrypted result is
- * statically allocated. (see MAX_PASS_LEN below).  This is necessary,
- * as the returned pointer points to "static data that are overwritten
- * by each call", (XPG3: XSI System Interface + Headers pg 109), and
- * this is a drop in replacement for crypt();
- *
