Stream-link tokens were AES-CBC with a fixed IV and no MAC. A modified token decrypts to modified bytes, and a padding error answers differently from a bad credential (auth.php: BAD_TOKEN vs everything after), so with enough requests anyone holding a link could read its username and password, or write a token of their own. Several consumers trust a token's contents as they stand: the live / vod / timeshift JSON (user_info, channel_info), HLS segment and key tokens, the web player's proxy URL (fetched server-side) and the MAG portal's verify token (passed to igbinary_unserialize). Encryption::seal()/open() add AES-256-GCM with a random nonce, as base64url(nonce ‖ ciphertext ‖ tag) — the same URL-safe alphabet, so no nginx route or pattern changes. Every stream-link token is now made with mintToken() and read with readToken(); StreamTokenCallSitesTest keeps new code from calling the legacy encrypt()/decrypt() for one. Deterministic encryption of stored data (HMAC keys looked up by ciphertext, image cache names) stays as it was. The new setting secure_stream_tokens (Settings → Tamper-proof Stream Tokens): - on: tokens are sealed, and the legacy format is refused wherever a token's contents are trusted. /play/ playlist and portal links, RTMP tokens and probe's /play/ links still read the old format — they carry credentials that are looked up again, and saved playlists hold them — and every token auth.php cannot read now counts against the address (BruteforceGuard), which stops reading an old one through the error responses. - off: legacy tokens are minted and every format is read. Servers on an older version cannot read sealed tokens, so migration 021 turns it off on a panel that has other servers (on for a single server, and for new installs); turn it on once every server is updated. key.php now also refuses a token that does not read, instead of serving the key of stream 0.
