#include <unistd.h> char * crypt( const char * key, const char * salt );
liblogin
Use the -l login option to qcc to link against this library.
We've deprecated the version of this function in libc. You should link against liblogin if your application authenticates users against the /etc/passwd and /etc/shadow files. |
The crypt() function performs password encryption. It's based on the Data Encryption Standard algorithm, and also includes code to deter key search attempts.
This function checks only the first eight characters of key. |
You can obtain a 56-bit key by taking the lowest 7 bits of key. The 56-bit key is used to repeatedly encrypt a constant string (usually all zeroes).
A pointer to the 13-character encrypted value, or NULL on failure. The first two characters of the encrypted value are the salt itself.
