Removes password security from a PDF you can open, entirely in the browser. Enter the user or owner password: the standard security handler is authenticated (RC4 40/128, AES-128 and AES-256, revisions 2–6), every string and stream is decrypted, and the file is written again without encryption or permission flags. The sample file opens with the password "sample". Without a valid password nothing is decrypted — this opens documents you are entitled to open, it does not break encryption.
