NAME
bigcrypt() — generate hashing encryption on large strings
SYNOPSIS
#include <hpsecurity.h>
#include <prot.h>
char *bigcrypt(char *key, char *salt);
DESCRIPTION
bigcrypt()
acts like
crypt(3C),
but handles much larger strings.
bigcrypt()
takes the segments of cleartext
and encrypts them individually, at first using the salt
passed in, and then using the first two characters of the
previous encrypted segment as the salt for the next segment.
This avoids duplicated ciphertext chunks when the password
characters are repeated, so that the encryption of a segment
involves the encryption of all the previous segments.
Each ciphertext segment is concatenated, with the salt at
the beginning, to form the entire encrypted string.
WARNINGS
HP-UX 11i Version 3 is the last release to support trusted systems
functionality.
