Summary: A decryption software will decrypt an encrypted DVD or Blu-ray disc and enables you to make copies of it for legal use. If you still hold doubts on this question, here are some related information about decryption methods as well as how to decrypt for your reference.
The 20-In-1 Versatile Solution Package
You may have been in a situation to copy a DVD or Blu-ray as a backup for later viewing. Nevertheless, some of them are encrypted, especially those DVDs or Blu-rays in high quality or definition. That is the time you need to seek a DVD or a Blu-ray decrypter for help. Find the best DVD decrypter.
There is some dispute as to whether it is legal and ethical to copy DVDs or Blu-rays. Typically, if you own a disc, it is legal to create a copy for your own personal use. So as long as you use your copy for your own personal viewing, and you never use it for illegal purpose, you should be well within the limits of the law. However, if you sell the DVD or Blu-ray disc or give it away, be sure to delete the corresponding files from your devices.
Because its huge storage, DVD discs are still an important part in people’s life. Yet in case you may accidently lost one of your favorite DVDs or you want to copy them before they are worn, you are in a need to copy your DVDs or you can rip and convert them to other video formats to play on other portable devices. Unfortunately, most DVDs are bogged down with copy protection, making it difficult to achieve copying or ripping. In order to copy or rip your DVDs for backup successfully, you will need a DVD decrypter to overcome these issues.
Before recommending the best and free DVD decrypter, we want to start from the basic knowledge that is telling you the DVD encryption technologies.
Some copy protection methods are commonly used on commercial pre-recorded DVD discs. They are Analog Protection System (APS) scrambling and Content Scramble System (CSS) encryption as well as Content Protection for Recordable Media (CPRM). Let’s introduce them one by one.
APS incorporated into about 75% of all DVD discs is the Macrovision DVD Copy Protection system, which is an enhanced version of the technology long used to protect video types. Through the method of manipulating the signal level of the composite video, video types copied from DVDs encoded with APS become garbled and unwatchable. Fortunately, Analog Protection System can be defeated by passing the composite video signal through a hardware device that restores the proper video signal levels.
Content Scramble System Encryption, shorted as CSS, is the main copy protection scheme applied to pre-recorded DVD discs. CSS works as a data interference system. Its main working idea is to set the global optical disc to six areas and protect each area with different technologies. Only the optical drive with the decoder of this area can correctly process the data in the optical disc. When using this technology protection, all the information stored in the optical disc needs to be processed by the encoding program. To access the encoded data, the data must be decoded.
CSS utilizes a proprietary 40-bit cipher that is used to encrypt the data stored on the DVD disc. When the disc is inserted into a player or computer, a series of “authentication” handshake key exchanges occur between the DVD drive and the player software. At the end of the “authentication” process, the drive allows access to the encrypted DVD data and the player can use the key it has obtained to decrypt the DVD data and play the disc.
Many DVD drives have a tendency to completely lock out access to an encrypted disc until the drive has been “authenticated”. In addition, many DVD drives will refuse to complete the “authentication” process and provide a decryption key if the disc and drive are not from the same region. Both of these situations can cause strange behavior and odd error messages on computer systems.
CPRM is a copy protection scheme that is used for Secure Digital (SD) memory cards and recordable DVD discs, including DVD-R, DVD+R, etc. Special CPRM-compatible recordable media are required, with each disc including a unique Media ID inscribed as a bar code in the inner hub area.
When a CPRM-compliant recorder detects compatible media, it uses the unique Media ID on the disc to encrypt the data it records to the disc. If the disc is copied, the Media ID on the new disc will be different and the recorded data will not decrypt correctly.
As many DVD protection schemes are used to encrypt DVDs, you are unable to copy an encrypted DVD. If you do so, you can only see some scrambled data. On such occasion, a DVD decryption software will do you a favor.
Are you curious about why we recommend this DVD decrypter when tons of other DVD decrypters are out there? Actually, the answer to this question is quite simple: DVDFab DVD Copy is a free and safe DVD decrypter software for you.

Blu-rays are for high definition entertainment. They are enjoying popularity due to their ability to give 1080p picture quality. While 4K UHD Blu-ray discs are capable of giving 4K picture quality. It is important to note that Blu-ray discs use a harder coating that is more difficult to scratch and damage, which is good, but the downside to this is once it does scratch, the Blu-ray disc typically becomes unusable and has to be replaced. Yet we all know that high definition stands for high price. The best way to prevent such things happen is to copy Blu-rays for backup in advance or you can rip your Blu-rays to play them on other devices. You will find it easy to decrypt Blu-ray.
The Blu-ray Disc standard mandates that all pre-recorded discs be protected by a copy-protection scheme. The copy protection used on pre-recorded discs is in practice only applied to the stream files and not to any other files that make up the format. A powerful Blu-ray decrypter is of great help.
The Advanced Access Content System is the first level of copy protection applied to pre-recorded discs. AACS is a standard for content distribution and digital rights management, intended to restrict access to and copying of the post-DVD generation of optical discs.
AACS includes a system by which the keys assigned to a particular player can be “revoked” for future Blu-ray disc releases if it is determined that those keys have been compromised. When a newer Blu-ray disc is inserted into an older drive, the drive is required to check the version of the “Media Key Block” (MKB) on the disc and, if it is newer than the one the drive has internally, to copy over to permanent non-volatile memory the newer MKB. Thus playing newer discs propagates the revoked key lists out to all drives.
BD+ Protection is the second level of copy protection that is optional for pre-recorded Blu-ray discs. After the stream files are encrypted using AACS encryption, they are further mangled randomly with instructions on how to repair the mangled files stored on the disc as special BD+ instructions. These instructions run in something called a “BD+ virtual machine”, special software that Blu-ray players are required to include. The virtual machine on the player runs the BD+ code on the disc and retrieves something called the “Fix-up Table” to repair all the BD+ mangled regions on the disc.
Cinavia is an advanced anti-piracy technology that embeds this technology (i.e. audio watermarks) into sound files to generate inaudible sound information. Even after re-encoding or external recording, Cinavia-generated anti-piracy cannot be eliminated. Information can still be identified by dedicated devices. Cinavia will embed certain protecting information in the sound of the film, such as embedding specific cinema-only information in the theater, embedding information that is only available for Blu-ray discs in Blu-ray discs, thereby preventing cinema piracy and Blu-ray Disc piracy. Cinavia has been widely used in new Blu-ray movies and Blu-ray players. More and more film manufactures use this technology.
