PDF Protector is an easy to use tool to encrypt or decrypt your PDF documents.
Set a password and allow PDF Protector encrypts documents to prevent others from opening. You can also set a different password that everyone who wants to copy or print the contents of your document must meet. Why PDF Protector also allows you to remove any of these security mechanisms, provided that you know the password. PDF Protector uses standard features of PDF, PDF works well with other applications. If you have to encrypt or decrypt a lot of documents with the same password, you can set a default password to be used by PDF Protector.
