I'm reaching out to the community on behalf on a customer as they are trying to use Perm ID.
Via Chrome, it's running fine but the customer machine only allows Explorer and when running it from the company machine, tthey ahve the following error:
HTTPS handshake to permid.org (for #475) failed. System.Security.Authentication.AuthenticationException A call to SSPI failed, see inner exception
From my finding, it relates to the Cipher Suites used by permid.org. Refer to https://www.ssllabs.com/ssltest/analyze.html?d=permid.org, permid.org supports the following Cipher Suites for TLS 1.2.
However, It looks like Windows 7 doesn’t support these cipher suites (https://social.technet.microsoft.com/Forums/ie/en-US/d1a10844-18fb-4400-b649-60183c5f58c6/how-to-add-cipher-suite-to-windows-7-tlsrsawithaes128gcmsha256?forum=w7itprosecurity).
I would like to confirm the problem statement. Does it mean that the OpenPermID website https://permid.org/ can't run properly on Internet Explorer?
I have tested it with the Internet Explorer on my Windows 10 machine. It can access the OpenPermID site properly.
