Rather than negating the result within the expression, you should do it in your code. That way, the expression becomes pretty simple.

Is the issuer's certificate present in the X509Store? A certificate is only valid if it's signed by someone you trust.
Is this a certificate from a real CA, or one that you signed yourself? Certificate signing tools often used by developers, like OpenSSL, don't add some important extensions by default. |
