Passkey Lite, a free version of Passkey, is a simple combination of Passkey for DVD and Passkey for Blu-ray. It is not any more a versatile and powerful decryption tool with some DVD/Blu-ray protections out of its domain. However, you can still freely watch any DVD, and use other software to access unprotected DVD/Blu-ray content.
Passkey Lite is a free and a simple two-in-one version of Passkey for DVD and Passkey for Blu-ray, and supports part of the functions they have. It can still decrypt protected DVD and Blu-ray, but not for all of them. For example, it can't remove AACS V12+, BD+, BDAV, and AVCREC for Blu-ray, so you are not allowed to watch movies with those protections. It doesn't support CPRM for DVD, and PathPlayer is not enabled, so ARccOS, RipGuard, FluxDVD, and CORE X2 can't be removed. As a result, you can't copy those still protected DVDs, but you are able to freely watch them.
What adds punch to Passkey Lite is it can work with all the software that Passkey for DVD and Passkey for Blu-ray works with. You are enabled to use these apps to play/copy/rip the unprotected DVD/Blu-ray discs.
* Remove part of DVD/Blu-ray protections * Work with other compatible software to access unprotected DVD/Blu-ray content * Freely watch any DVD with no region limit
