Hi,

Im trying to decrypt SSL traffic and I keep getting an alternating SSL error.  It's either Subject Alternative Name missing or Common Name Invalid.

I've changed the engine to CertEnroll and cleared old certs, retsarted browser and Fid but no good.

The site I'm trying decrypt is part of an IIS WebFarm which uses Centralised Certificates so the SAN is needed to lookup the correct cert to perform the handshake so I think this is the issue.

Fiddler: 4.5.1.2

Chrome: 74.0.3729.131 32bit

 

Any ideas?

 

Many Thanks,

Brad

Hi Bradley,

Have you tried using the Bouncy Castle implementation of the Fiddler Certificate generator? Here is a link.
