SetaPDF Components Released in Version

This release ensures the handling of encrypted PDF documents with an incompatible setup of OpenSSL and PHP. While the installations of OpenSSL 3.0 are raising we encountered several customer environments on which this version is installed with PHP < 8.1 while this construct isn't supported by PHP. Sadly this construct doesn't throw or generate any error but some OpenSSL methods "lie" about supported ciphers which SetaPDF depends on (and the PDF format in general). If this situation is encountered SetaPDF will throw an exception now to give you the chance to repair your setup. This can be done by enabling legacy providers or by installing a compatible OpenSSL version.

It is also possible to bypass this check and force the use of a PHP implementation of the required legacy cipher (RC4/Arcfour) - keep in mind that this is slower.

Beside some new nice features in the SetaPDF-Signer componente we did a lot of code clean-up in view to data type consistency in all components.
