The next best way to avoid the browser warning is to trust the server's certificate. Where and when exactly are you trying to show these pages? The site's security certificate is not trusted! @johnpoz Thanks I’ll try the CA Mgr & report back. All the commands and steps will remain the same as we used above to generate self signed certificate, the only difference would be that we will not use any encryption method while we create private key in step 1 . The sections below are commented. OpenSSL does not provide a command-line way to specify this, so many developers' tutorials and bookmarks are suddenly outdated. I didn't check if this is in the standard or not. But I still recommend using it as a good habit of not using outdated / insecure cryptographic hash functions. I'll use it sparingly. All necessary steps are executed by a single OpenSSL invocation: from private key generation up to the self-signed certificate. Created Jan 9, 2018. But I would encourage you to become your own authority. Generate a self signed certificate without passphrase for private key - create-ssl-cert.sh.

This topic tells you how to generate self-signed SSL certificate requests using the OpenSSL toolkit to enable HTTPS connections. As explained, it doesn't make sense to use short expiration or weak crypto. ^ exactly!! Well, I'm disappointed to learn this. That means the Subject and Issuer are the same entity, CA is set to true in Basic Constraints (it should also be marked as critical), key usage is keyCertSign and crlSign (if you are using CRLs), and the Subject Key Identifier (SKI) is the same as the Authority Key Identifier (AKI). So far pretty straight forward. Related: browsers follow the CA/Browser Forum policies; and not the IETF policies. Per may 2017 Chrome doesn't accept certs w/o (emtpy) SAN's anymore: "The certificate for this site does not contain a Subject Alternative Name extension containing a domain name or IP address.
