Decryption is being done instantly. Decrypted file can be opened in any PDF viewer (e.g. Adobe Acrobat Reader) without any restrictions - i.e. with edit/copy/print functions enabled. All versions of Adobe Acrobat (including 5.x, which features 128-bit encryption) are supported. The standard security provided by PDF consists of two different methods and two different passwords.

Recover PDF Password is a very useful application that allows searching for a password of password-protected PDF documents. Recover PDF Password allows its users to search for "user" password, which prevents opening a PDF file and "owner" password, which protects information in PDF from being printed, copied or edited. If your PDF file is protected only with "owner" password you can use "Decrypt" option and create an unprotected copy of PDF file even without searching for the password. No matter if your password-protected PDF document is old or new, Recover PDF Password fully supports all versions of Adobe Acrobat and can recover Unicode passwords for protected Acrobat 9.x files. Recover PDF Password provides you with 3 comprehensive methods of searching for the lost password, recovers passwords in various languages and stores all already decrypted file passwords.
