xcrypt(3R)
NAME
xcrypt, xdecrypt, passwd2des − hex encryption and utility routines
SYNOPSIS
xencrypt(data, key)
char ∗data;
char ∗key;
xdecrypt(data, key)
char ∗data;
char ∗key;
passwd2des(pass, key)
char ∗pass;
char ∗key;
DESCRIPTION
The routines xencrypt and xdecrypt take NULL-terminated hexadecimal strings as arguments, and encrypt them using the 8-byte key as input to the DES algorithm. The input strings must have a length that is a multiple on 16 hex digits (64 bits is the DES block size).
passwd2des converts a password, of arbitrary length, into an 8-byte DES key, with odd-parity set in the low bit of each byte. The high-order bit of each input byte is ignored.
These routines are used by the DES authentication subsystem for encrypting and decrypting the secret keys stored in the publickey database.
