i think there's an error in the man page for crypt()...
usage: char *crypt(const char *key, const char *salt);
from the man page:
salt is a two-character string chosen from the set
[a-zA-Z0-9./]. This string is used to perturb the algo-
rithm in one of 4096 different ways.
If the salt starts with $1$ an MD5 based password hashing
algoritm is applied. The salt should consist off $1$ fol-
lowed with eight characters.
the program:
#include<stdio.h>
#include<crypt.h>
int main(int argc, char *argv[])
{
char salt1[] = "ab";
char salt2[] = "$1$12345678";
char key[] = "password"; /* :-) */
char *pass1 = crypt(salt1, key);
char *pass2 = crypt(salt2, key);
printf("DES: %s\nMD5: %s\n", pass1, pass2);
return(0);
}
the compile:
gcc -lcrypt -Wall -ansi -pedantic crypto.c
the output:
# ./a.out
DES: paWN9Y6oTBa/Q
MD5: paWN9Y6oTBa/Q
i assume they're both DES. help?
