Passing base64 encoded strings in URL

Question

Is it safe to pass raw base64 encoded strings via GET parameters?

Answer 1

@joeshmo Or instead of writing a helper function, you could just urlencode the base64 encoded string. This would do the exact same thing as your helper function, but without the need of two extra functions.

$str = 'Some String';

$encoded = urlencode( base64_encode( $str ) );
$decoded = base64_decode( urldecode( $encoded ) );
