  1. Hai man. Email sau telefon de suport nu au? Nu mutati suportul de acolo aici pe forum. I s-a permis sa-si faca aici thread cu serviciile lui, mascat de un titlu care nu are nicio treaba, dar suport nu vrem sa oferim aici pentru ce ofera el. E totusi un serviciu comercial, iar aici suntem doar o mana de oameni care nu profitam cu nimic de pe urma forumului.

  2. The block was put in place at the end of July and is enforced via China's Great Firewall. The Chinese government has deployed an update to its national censorship tool, known as the Great Firewall (GFW), to block encrypted HTTPS connections that are being set up using modern, interception-proof protocols and technologies. The ban has been in place for at least a week, since the end of July, according to a joint report published this week by three organizations tracking Chinese censorship -- iYouPort, the University of Maryland, and the Great Firewall Report. CHINA NOW BLOCKING HTTPS+TLS1.3+ESNI Through the new GFW update, Chinese officials are only targeting HTTPS traffic that is being set up with new technologies like TLS 1.3 and ESNI (Encrypted Server Name Indication). Other HTTPS traffic is still allowed through the Great Firewall, if it uses older versions of the same protocols -- such as TLS 1.1 or 1.2, or SNI (Server Name Indication). For HTTPS connections set up via these older protocols, Chinese censors can infer to what domain a user is trying to connect. This is done by looking at the (plaintext) SNI field in the early stages of an HTTPS connections. In HTTPS connections set up via the newer TLS 1.3, the SNI field can be hidden via ESNI, the encrypted version of the old SNI. As TLS 1.3 usage continues to grow around the web, HTTPS traffic where TLS 1.3 and ESNI is used is now giving Chinese sensors headaches, as they're now finding it harder to filter HTTPS traffic and control what content the Chinese population can access. Image: Qualys SSL Labs (via SixGen) Per the findings of the joint report, the Chinese government is currently dropping all HTTPS traffic where TLS 1.3 and ESNI are used, and temporarily banning the IP addresses involved in the connection, for small intervals of time that can vary between two and three minutes. SOME CIRCUMVENTION METHODS EXIST... FOR NOW For now, iYouPort, the University of Maryland, and the Great Firewall Report said they were able to find six circumvention techniques that can be applied client-side (inside apps and software) and four that can be applied server-side (on servers and app backends) to bypass the GFW's current block. ZDNet also confirmed the report's findings with two additional sources -- namely members of a US telecommunications provider and an internet exchange point (IXP) -- using instructions provided in this mailing list Via zdnet.com.

  3. Salutare, as vrea sa gasesc pe cineva care se pricepe la Javascript si Python sa preia de la mine 2 proiecte. Beneficiarul plateste 30 euro / ora pentru programare si 10 euro / ora pentru restul (convorbiri, documentatie, etc). Proiectele sunt functionale dar necesita mentenanta si imbunatatiri, plus ca beneficiarul nu se pricepe la linux. Deci totul trebuie explicat cu rabdare. Multam mihk

  4. TLS 1.3 cu ESNI. Cred ca toate detaliile sunt aici: https://blog.cloudflare.com/esni/

  5. Aici nu vorba de trafic slab ci de faptul ca ceea ce blocheaza acum nu poate fi monitorizat. In pachetele TLS in general se poate vedea serverul destinatie (e.g. rstforums.com). Ei bine, cu acest nou feature, nu se mai vede si ei nu au cum sa stie pe ce site-uri intra oamenii...
