As a rule the security provided by Acrobat PDF consists of two different methods and two different passwords, user password and owner password.
An encrypted file which has the owner password set is impossible to copy, edit or print. In case your PDF file is user password protected you can’t even open it.
Very often after owner or user password was set people forget or lose them. That’s why software vendors constantly develop different password recovery tools to solve such problems.
One of such utilities is Recover PDF Password for Mac by Eltima Software. It easlily recovers even the most complicated user or owner passwords created in all versions of Adobe Acrobat.
Since the most common task is recovering the lost owner passwords of PDF files, Eltima Software improved its Recover PDF Password for Mac to simplify this process.
From now on if the PDF file is protected only with owner password (i.e. the file has no user password protection) there is no need to search for it and then enter the password in Adobe Acrobat to open the PDF file. The new version of Recover PDF Password enables adobe users to drag and drop a file into the app, press the "Decrypt" button and immediately save a copy of the file with protection removed.
If the PDF file was protected with unknown user password (or both user and owner password) the decryption option is still available. First Recover PDF Password will search for user or owner password. Afterwards, decryption option can be used in order to create unprotected copies of PDF files.
Recover PDF Password uses various methods to recover lost passwords: by password length, by template or exhaustive search method. All methods are provided to be successful, however, exhaustive search requires maximum time. It supports all character encodings and is able to recover passwords, typed in any input languages and in any keyboard layout. Moreover, Recover PDF Password can retrieve Unicode Passwords for protected Acrobat 9.x files.
