+       The glibc2 version of this function supports additional encryption algorithms.
+
+       If salt is a character string starting with the characters "$id$" followed by a string terminated by "$":
+
+              $id$salt$encrypted
+
+       then instead of using the DES machine, id identifies the encryption method used and this then determines how the rest of the password string  is  inter-
+       preted.  The following values of id are supported:
+
+              ID  | Method
+              ---------------------------------------------------------
+              1   | MD5
+              2a  | Blowfish (not in mainline glibc; added in some
+                  | Linux distributions)
+              5   | SHA-256 (since glibc 2.7)
