The crypt class provides an encryption method that is commonly used for password encryption.
static char* crypt::encrypt | ( | const char * | password, |
const char * | salt | ||
) | [static] |
Encrypts "password" using the des algorithm and "salt" (which should be a 2 character string from the set [a-zA-Z0-9./].
Returns the encrypted password on success or NULL on failure.
Note that this method allocates a buffer internally and returns it. The calling program must deallocate this buffer.
static bool crypt::needsMutex | ( | ) | [static] |
If your system doesn't support crypt_r() then this class needs a mutex to assure thread safety.
This method returns true if this class needs a mutex to operate safely in a threaded environment and false otherwise.
static void crypt::setMutex | ( | mutex * | mtx | ) | [static] |
Allows you to supply a mutex is the class needs it. If your application is not multithreaded, then there is no need to supply a mutex.
