Site userid:
https://macgirvin.com/1
-$guuid = base64url_encode(hash('whirlpool','https://macgirvin.com/1.' . mt_rand(1000000,9999999),1);
+$guuid = Strings::base64UrlEncode(hash('whirlpool','https://macgirvin.com/1.' . mt_rand(1000000,9999999),1);
Then create a hashed site destination.
-$gduid = base64url_encode(hash('whirlpool', $guuid . 'https://macgirvin.com',1);
+$gduid = Strings::base64UrlEncode(hash('whirlpool', $guuid . 'https://macgirvin.com',1);
