I have libvirt, one client and one server. Libvirt uses gnutls implementation of tls. I want to use mitmproxy and put in the middle between client and remote server. But mitmproxy uses different implementation of tls - openssl. I read that their certificates and maybe handshake process are not compatible with each other?
Are there any suggestions on which steps should be taken to achieve compatibility or I should just provide for mitmproxy one more implementation of tls layer using gnutls?
Is it possible to make OpenSSL work with gnutls?
No of course not. - Yes of course.
Both do, more or less, exactly the same thing: they are crypto libraries that provide as different implementations support for (the same) cryptographic protocols to OTHER applications.
Openssl doesn't need to and can't use gnutls libraries and vice-versa won't need to happen either.
On the other hand: APPLICATIONS linked to OpenSSL libraries can of course communicate with other applications that are instead linked to GnuTLS, as long as
I read that their certificates and maybe handshake process are not compatible with each other?
Uhh, where?
As long as they both implement the protocol correctly there is no a priori reason why you should have compatibility issues.
