There are two types of secured PDF documents: your file can ask for password when opening the document, or, your file opens normally, but some operations are restricted (e.g, printing or editing) and requires password for unlocking it. The first password is known as document open (or user) password, and the second is permissions password (also known as a master or owner password). Adobe Acrobat uses different algorithms to apply PDF security with 40, 128 and 256 bit keys.

PDF restrictions are insecure and permissions password could be removed instantly.
If open password uses 40-bit keys (Acrobat 3 compatible encryption), it also could be removed with guarantee.
Searching for open password with 128 or 256-bit PDF encryption is only possible using PDF password recovery software.
