crypt base64 url safe

[xAockd]

When I make hash($crypt->encryptBase64), for send url, hash look like

QGTBGorKoHBAGx/0qbtFjI6+iM3Eyggahl0KXER+iJUHUlrdcHb3zQF/VqGQeTJpfUYIi4kITryS0oQJLfVg==

Hash has special chars like '/' and '+'

It would be nice if we had something like $crypt->encryptbase64safeUrL() and $crypt->decryptbase64safeUrL().

Where base64 with + and / replaced with - and _

This conforms to rfc 4648.

I try complete it.

$crypt->encryptBase64($text, $key, $safe);
$crypt->decryptbase64($text, $key, $safe);
