Try https://outline.com/C4GN8n Or the archive link http://archive.is/7p6ZI Alternatively look into a secure proxy or a vpn. Azza
Azza sorry to distract from your question... I think the answer is PKI... public and private keys. hashing is only one element, but if you are seeking two elements, then key exchange is prevalent.
Code Crasher If that website had a self-signed or expired certificate, it appears to have been updated with one from Let's Encrypt effective May 17, 2020 thru Aug 15, 2020. Azza Can you give it another try? Will the website load for you now? How kismet is it that the issue in accessing an article about cryptography on a Q&A Post inquirying about cryptography might be related to a secure certificate? 🤔😂
Azza how about the home page without ssl? I wonder if you are being filtered? 🤔 http://tails.boum.org/index.en.html Lord Krishna may be right... you may need a vpn or proxy in another locale to get access to sites like that. Seems odd, but I have seen stranger situations.
Azza are you on an iOS device? it makes all the difference. I can get to that link from an adroid VM, Chrome on multiple devices, and iOS devices up to 12.4.1. iOS 13 fails and I have no option to bypass the security alert. It might be apple playing Internet Gaurdian for us?!
Azza Internet Gaurdian is just a term describing how some manufacturers try to protect consumers from themselves. However, in the process they just make it inconvienent for others. I agree to the practice if there is a way to temporarily or selectively turn such restrictions off in special situations, but that is becoming rare. 😣
David Carroll Apple is not only preventing users to visit sites with self-signed or expired certificates, but they also have started using a web filtering service at the os level. I guess they are finally using some of the "anonymous" tracking data that have been collecting all these years? 😳 previous versions you could turn off or set the maturity level of content. I haven't found a way to turn it off yet, but I am always looking.
Code Crasher David Carroll Your discussion is very enjoyable .. I am grateful for your attempts to understand the problem and solve it 😇 No the first link is still not working, my luck looks so bad 😂
Azza are you using Safari or Chrome? Maybe it is the redirect causing an issue? try this link... https://tails.boum.org/doc/encryption_and_privacy/gpgapplet/public-key_cryptography/index.en.html formatting is a little off on Chrome. I am curious now. lol
Code Crasher Safari ..still not working :(
Azza that is interesting. If you have a ping utility on your device, try: ping 18.104.22.168 you can try this link in a browser also: http://22.214.171.124 the link will show a "Welcome to nginx on Debian!" page. If you can use the IP it will tell us that dns is not working for some reason. If you can not reach the server by the IP then I would say there is a filter in place either on the client machine or possibly somewhere in the path to the server. It looks like boum.org is in France. You could also try: traceroute 126.96.36.199 to see where the traffic is being stopped. There are numerous reasons for such symptoms, but they are not easily determined with just a web browser. Let me know if you want to continue to explore this, and DM me if you want some help. 😉👍
Azza what happens when you attempt to visit that link? Is it possibly blocked from your location?
David Carroll I cant open it, maybe.. I don't know what’s the problem
Azza Details help. Do you get any messages? Does the URL address redirect? Have you tested from other machines or devices? Different networks? Over a VPN? Are you in a country that blocks websites? It could be so many things. I'm just curious of what it could be. No worries if these question are beyond your interest. 😉
David Carroll It appears that a secure connection to the server could not be established 😅🤷🏻♀️
Yes on iOS 13.1.3 :( what’s mean apple playing Internet Gaurdian ?! It’s ok,no need to apologize🌸 Thank you so much Code Crasher
Azza / Code Crasher Thanks for helping me understand this issue is related to iOS 13+. I'll remember this for future issues from others. 🙏
David Carroll that is funny. I can get to that link now. I noticed the archive.is link this time around too. That link works fine as well. 👍 Azza if the first link doesn't work it is likely a cache issue at this point. delete your web data or just use the second link. The browser should figure it out though if you hit refresh. 😉
Code Crasher Same not work🤯
