encryptStream documentation could use a little more code

[lekoala]

so i was using this bit of code

$input = \fopen('/tmp/super-secret', 'rb');
$output = \fopen('php://temp', 'wb');
$encFile->encryptStream($input, $output);

then, I expected this to work

file_put_contents($filename, $output);

but I ended up with an empty file! Surely something must be wrong? And yes, because the pointer is at the end of the file !

so either, I need to do this

rewind($output);
file_put_contents($path, $output);

or encryptStream should return a rewinded stream

anyway, it's probably worth mentionning just for other people like me that might otherwise end up scratching their head for no reasons :-)

and the same apply for decryptStream

Nice!
