tsdecrypt reads an incoming MPEG transport stream over UDP/RTP and then decrypts it using keys obtained from OSCAM or a similar CAM server. Currently supported crypto systems are Conax, Cryptoworks, Irdeto, Viaccess, Mediaguard (Seca), Videoguard (NDS), Nagra, DRE-Crypt, and Bulcrypt. BISS and constant code words are also supported. tsdecrypt communicates with a CAM server using the cs378x (camd35 over TCP) protocol or the newcamd protocol.
MakeMKV is a one-click solution to convert video from DVD or Blu-ray discs into MKV, which is a free and patent-unencumbered format that can be played everywhere. MakeMKV is a format converter or "transcoder". The only thing it does is convert video clips from a (usually encrypted) disc into a set of MKV files, preserving most information but not changing it in any way. The MKV format can store multiple video and audio tracks with all meta-information and preserve chapters.
MEO is a powerful data encryption application to encrypt or decrypt files of any type, including Microsoft Word, email, and PDF documents. It can also create self-extracting encrypted files. This is handy for those who like to view their encrypted files without installing any other encryption software. Also, many downloads supply a checksum or hash value for you to verify the integrity of your download. Meo allows you to create and verify MD5 checksums, SHA-1 hashes, and Tiger Tree hashes.
