What can I do with a certificate?

Before checking how to steal the certificates here you have some info about how to find what the certificate is useful for:

1) cmd

certutil.exe -dump -v cert.pfx

2) powershell

$CertPath = "C:\path\to\cert.pfx"

$CertPass = "P@ssw0rd"

$Cert = New-Object

System.Security.Cryptography.X509Certificates.X509Certificate2 @($CertPath, $CertPass)
