Decrypt Certificate-Protected PDFs

I have a handful of PDF documents that were locked with certificate-based encryption. The certificates are company-issued, and unfortunately I no longer have the matching certificates or private keys. I need someone who can still remove the encryption so that I can open, read, and edit the files normally.

You will receive the encrypted PDFs immediately after project start. Your task is to return fully decrypted copies that preserve the original layout, images, and metadata.

If your workflow relies on tools such as OpenSSL, QPDF, or any other specialized forensic utilities, just let me know—whatever gets the job done cleanly. A short outline of your approach (no trade secrets, just enough to confirm feasibility) will help me award the project quickly.

This an example, if you can decrypte it i'll send the remaining files
