Free aca software for windows

DumpHD is a HD-DVD decrypter based on the idea of BackupHDDVD by muslix64.
It uses a key database to decrypt the files. The goal of this program is to make a perfect backup without any traces of AACS.
This programm is written entirely in Java and requires the JRE 1.5 or later.
It should run on every platform that supports Java.
It is HIGHLY recommended to use the Server VM, the Client VM suffers a SEVERE performance drop, almost by factor 1.8.
Main features:
- Dual-Core supported decryption of EVO files (for harddisk to harddisk speed records )
- Support for every pack type of an EVO (including in-place decryption of ADV_PCKs - slightly incomplete, excluding Sequence Key Sections)
- Decryption of every ARF protection type
- The same key database format as BackupHDDVD
- Single file or complete disc mode
- Supports HD-DVDs for Advanced Content only
- Very much console output for free
Two additional support utilities are included:
PackScanner
-----------
Scans EVO files for pack types and has the ability to "blank" VC-1 / DD+ Secondary Streams for a "IME-Fix".
ACAPacker
---------
A tool for packing, depacking and repacking (ACA -> ACA) ACA files, with or without AACS processing,
including a list function to show the contents of an ACA file.
For the BluRay part, there are three important changes from BackupBluRay:
1. The keys for the BluRay movies are stored in the same file as for the HD-DVD movies, KEYDB.cfg
2. The key entry format has slightly changed, it is now consistent with the HD-DVD key format. There is now a key type field and the CPS Unit Keys are numbered like the Title Keys. All up today released CPS Unit Keys have the number 1.
3. The SHA-1 hash of a different file is used as Disc Identifier
This is the most important change, the new Disc Identifier is the SHA-1 hash of the file AACSUnit_Key_RO.inf. This change was necessary because the Disc Identifier chosen by BackupBluRay is not unique per disc, there were already duplicate IDs for different discs.
