PDF Unlocker YU-MING HSU

For encrypted PDFs whose password you already know: pick the file, enter the password once, and save an unlocked copy that opens without a password from then on. The original encrypted file is left untouched. AES-encrypted PDFs are supported. This is not a cracking tool — a wrong password simply fails; there is no guessing, brute force, or bypass of any kind. Use it only on files you own and know the password to.
