Acrobat Password Recovery Key

Acrobat Key is a program to recover user passwords for Adobe Acrobat PDF files.

Features

• All versions through Adobe Acrobat 5.0 are supported
• Recovers user password required to open the file
• Decrypts PDF files protected with owner passwords  
• Brute-Force, Xieve™ or Dictionary attacks are used to recover the password
• Additional user dictionaries support, case changes, multiple mistypes and other modifications for each dictionary word
• Program automatically saves password search state and can resume after a stop or a crash
• Patterns can be used to minimize search time if any part of the password is known
• Non-English characters in passwords are supported
• Full install/uninstall support

Xieve™

• Passware developed Xieve™ optimization that boosts dramatically Brute-Force attack speed by skipping password checks of nonsense combinations of characters. With 95% recovery rate for English words password search speed is over 1 500 000 000 passwords per minute.

Limitations

• Adobe Acrobat uses relatively strong encryption algorithm that makes instant password calculation impossible. Brute-force attack is the slowest approach and can test all the passwords of up to 8 characters. Xieve™ attack is much faster and is capable of recovering passwords of up to 10 characters. Dictionary attack is the fastest method - there's no limitation on password length.
