I got a email from George yesterday. he said,
Hi,
I found your pdfcrypt program and wrote a CMD file that, if you place it in the same folder as pdfcrypt.exe, will let you drag an encrypted (but non-password protected) PDF onto the .cmd file to make a decrypted copy of the PDF in the same folder as the original. I put it under the GPL, so you can redistribute it with pdfcrypt, or post it on your site, or ignore it completely.
The script is attached with a .txt extension so that it is not flagged as a potential threat. You can look through it to ensure it does nothing but facilitate decrypting.Thanks for your work pdfcrypt, it is much appreciated!
George
And here is the code he contributed, thanks for George’s kindness.
