+"""xtremestream (player perverzija): manifest HLS z segmentami AES-128 skladany po stronie backendu.
+
+Od ok. 2026-10-12 player (`ftk_engine.js`, zaciemniony, z blokada devtools) nie gra juz
+z `xs1.php`: segmenty pod starymi adresami `/cdn/down/<id>/<q>/<q><i>.html` oddaja 404,
+a prawdziwe leza pod `/cdn/down/<id>/<q>_enc/<q><i>.html` i sa zaszyfrowane AES-128-CBC,
+IV = numer segmentu (16 bajtow big-endian), dopelnienie PKCS7, czyli dokladnie tak jak
+standardowe `#EXT-X-KEY:METHOD=AES-128` bez atrybutu IV (sprawdzone 2026-10-14: openssl
+z kluczem i IV=0 daje poprawny MPEG-TS, ffprobe widzi h264 i aac).
+
+Klucz (16 B) oddaje `proto_api.php?data=<id>&op=key&vt=<vt>` z naglowkiem `X-XS-P: 1`.
+`vt` to token ze strony playera (`XSFTK.boot(id, vt, player)`), zwiazany z IP i UA
+pobierajacego (ten sam vt z innego IP = 403 `forbidden-vt`), ale klucz jest jeden na film,
+niezalezny od vt (sprawdzone z dwoch IP). Segmenty i stary manifest `xs1.php` (nadal
+serwowany, z dobrymi dlugosciami i rotacja hostow cdn[i % n]) nie sa zwiazane z IP.
+
+Dlatego telefon nic nie musi robic: backend bierze `xs1.php`, przepisuje sciezki na `_enc`,
+dokleja `#EXT-X-KEY` z URI wzglednym `key.bin`, a `/proxy/hls/<token>/key.bin` oddaje klucz
+pobrany na wlasny vt. Telefon ciagnie segmenty prosto z CDN (przez VPS leci ~50 kB manifestu
+i 16 B klucza). Czesc katalogu (starszy storage) ma nadal zwykle segmenty: wtedy manifest
+idzie bez klucza, tak jak dotad.
