+     <constant>CRYPT_EXT_DES</constant> - Extended DES-based encryption. The "salt" is a 
+     9-character string consisting of an underscore followed by 4 bytes of iteration count and 4
+     bytes of salt. These are encoded as printable characters, 6 bits per character, least 
+     significant character first. The values 0 to 63 are encoded as "./0-9A-Za-z".
