We have recently had a need for a script like this (v5.0.2). We found a few complaints about "use OpenEMR\Common\Crypto\CryptoGen;" and also didn't like the idea of needing to sort through duplicates of files, so we moved them outside OpenEMR. I might suggest that $target_dir be parameterized to assure the path exists. Further, because we stored documents on a cloud file system (AWS EFS), we found improved performance decrypting and copying to a local drive (instead of making a round trip to EFS). Content is included in the subsequent comment. This might be a useful utility to have handy within source. @stephenwaite
