Decode IonCube & SourceGuardian Safely

I need a practical way to perform in-depth security analysis on commercial PHP packages that arrive encrypted. The solution must lift the protection on both IonCube (versions 10–15) and SourceGuardian (versions 11–17) so I can audit the true code that eventually runs under PHP 7.1 up to PHP 8.4...
