Hey Dixit, To get a response you would need to respond in the Bugzilla. Maybe Alex might be able to answer some of your questions about the subject. All The Bests, Eliezer From: DIXIT Ankit <Ankit.Dixit@xxxxxxxxxxxx> Elizer,
* Short-term: Essentially disable OpenSSL built-in certificate validation (for certificates with missing intermediate CAs) and perform that validation from Squid, using X509_verify_cert(), after SSL_connect() returns control to Squid and Squid fetches the missing CAs. This approach still requires some non-trivial Squid development and keeping an eye on OpenSSL built-in validation logic, but it can be completed without OpenSSL modifications and, IMHO, without replicating a lot of OpenSSL internal validation logic. * Long-term: We need a new OpenSSL callback for pausing OpenSSL processing after TLS v1.3 server handshake is decrypted and before certificate validation starts.

Regards, Ankit Dixit|IS Cloud Team Eurostar International Ltd Times House | Bravingtons Walk | London N1 9AW Office: +44 (0)207 84 35550 (Extension– 35530) From: DIXIT Ankit Subject changed Elizer/Team, Connecting with you again after we upgraded to Squid version 4. We have blacklisted the domain categories on Squid Proxy, but we are getting below exception in cache.log and due to this internet is not flowing from client servers via squid. This blacklist category is having thousands of blacklisted domains. kid1| Error negotiating SSL on FD 33: error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed (1/-1/0) kid1| Error negotiating SSL connection on FD 26: (104) Connection reset by peer Is there any specific ssl certificate, we need to configure? Or any other issue, you see here? Regards, Ankit Dixit|IS Cloud Team Eurostar International Ltd Times House | Bravingtons Walk | London N1 9AW Office: +44 (0)207 84 35550 (Extension– 35530) From: DIXIT Ankit Elizer, SSL was failing for few applications but was working fine for other applications. So we reverted back to old version. I am not sure what ssl certificate dependency was there. Would be great, if you can suggest memory leak solutions in 3.12 version.
