limelect 48 Posted October 21 (edited) I am using tothpaul\Delphi-master\Indy.SChannel with great success in testing my software However, my provider did an update on his server and now I cannot get my text file at https://limelect.com/UpDate/document-projects.txt I get a protocol error My provider answered me this "So the problem is probably in the software settings. See that TLS is at least 1.2 And in addition, make sure that there is trust for the SSL certificate" I was looking into finding SSL version and could not find a good source for that I was trying this answer without any success https://stackoverflow.com/questions/41127514/how-to-determine-which-tls-ssl-protocol-was-negotiated-when-using-sslvsslv23 Any idea what I should do next? No DLL plz P.S D10.2.3 Indy 10 Edited October 21 by limelect Share this post Link to post

There is a commercial add on to Indy called YuOpenSSL, that replaces OpenSSL DLLs with Delphi DCUs. Share this post Link to post

Angus Robertson 575 Posted October 29 I integrated YuOpenSSL into ICS three years ago and alternate using it and OpenSSL for testing. ICS also allows the OpenSSLs to be compiled into applications as resources to ease distribution and DLL hell, all three variants work identically. But applications are larger with YuOpenSSL or resource files. Using SChannel may seem simpler, but your cryptography and updates are then locked to the OS, Microsoft only reluctantly support TLS/1,2 With Windows 2008 but did not support EC certificates, and TLS/1.3 took a long time to arrive. In ICS, I've worked with many of the Windows crypto APIs, and they are horrible. Angus Angus 2 Share this post Link to post
limelect 48 Posted October 30 (edited) My test with SChannel After my provided did not help much I communicated with 2 more providers. One had the same problem that I could not use his server with SChannel but the other one was OK. While testing I found that on Windows 7 things did not work but with Windows 11 was OK. No one understands what is going on. In my case, I had to move to a new provider where the SChannel worked. with Windows 7 Edited October 30 by limelect Share this post Link to post
