Implementation status: partially implemented
char *crypt(const char *key, const char *salt);
crypt() function is a string encoding function.
key - a string to be encoded.
salt - a string of at least two bytes in length not including the null character chosen from the set of letters (small and capital), digits, point and slash.
The first two bytes of the salt string are used to perturb the encoding algorithm.
The return value of
crypt() points to static data that is overwritten by each call.
The use of
crypt() for anything other than password hashing is not recommended.
On success this function returns a pointer to the encoded string. The first two bytes of the returned value are those of the salt argument.
Otherwise, the function returns a null pointer and sets
errno to indicate the error.
ENOSYS] - The functionality is not supported on this implementation.
- Implement error detection.
