Some notes on recording encryption.

Stock firmware

  • Every recording made by the Humax is encrypted before being stored on disk;
  • The encryption key is unique to each box and believed to be stored in an on-chip Hardware Security Module (HSM);
  • Copying a standard definition recording to an external disk (connected via USB) results in the Humax decrypting the file in the process [HDR model only];
  • Copying a high definition recording to an external disk will NOT decrypt it;
  • The HDR features a built-in FTP server but this only provides access to the raw files on disk. If you download files from the Humax via FTP, they will remain encrypted;
  • The HDR features a built-in DLNA media server which serves decrypted content to DLNA clients. However, it will only stream high definition content to clients that negotiate Digital Transmission Content Protection (DTCP);
