Decrypter/Detagger Filter

This topic applies to Windows XP Service Pack 1 only.

The Decrypter/Detagger filter conditionally decrypts samples that are encrypted by the Encrypter/Tagger filter.

This filter reads ratings information from the encrypted samples and passes them to the EvalRat object. The EvalRat object determines whether the content is allowed. If so, the Decrypter/Detagger filter decrypts the samples and passes them downstream for rendering.
