void passwd2des(char *passwd, char *key);
int xencrypt(char *secret, char *passwd);
int xdecrypt(char *secret, char *passwd);
Описание (Description)
WARNING: Do not use these functions in new code. They do not
achieve any type of acceptable cryptographic security guarantees.
The function passwd2des() takes a character string passwd of
arbitrary length and fills a character array key of length 8.
The array key is suitable for use as DES key. It has odd parity
set in bit 0 of each byte. Both other functions described here
use this function to turn their argument passwd into a DES key.
The xencrypt() function takes the ASCII character string secret
given in hex, which must have a length that is a multiple of 16,
encrypts it using the DES key derived from passwd by
passwd2des(), and outputs the result again in secret as a hex
string of the same length.
The xdecrypt() function performs the converse operation.
Возвращаемое значение (Return value)
The functions xencrypt() and xdecrypt() return 1 on success and 0
on error.
Версии (Versions)
These functions are available in glibc since version 2.1.
