In this context, the double ones will first check the left parameter and its value and if true (||) or false (&&) leave the second one untouched.

How to use "and" and "or" in a "Where" clause - Stack Overflow. I have a query that is gathering information based on a set of conditions.

Another key aspect involves, to use the public key contained in the certificate (and signed by the signature in the certificate) you should use any library that parses X.509 certificates and performs RSA encryption.

You could use a tool that detects/handles PEM encoding or you could first convert the certificate to DER by stripping off the PEM encoding. The OpenSSL command line contains lots of options to convert between ... It's important to note that, multiple -and -or in PowerShell Where-Object statement. By wrapping your comparisons in {} in your first example you are creating ScriptBlocks; so the PowerShell interpreter views it as Where-Object { <ScriptBlock> -and <ScriptBlock> }.
