GroupDocs.Signature provides CertificateSearchOptions class to specify different options to search text data within the certificate documents. Please be aware that the search result will be always as the MetadataSignature.

Here are the steps to search for the values within the certificate document with GroupDocs.Signature:

Create new instance of Signature class and pass source document path as a constructor parameter.
Instantiate the CertificateSearchOptions object according to your requirements and specify search options.
Call Search method of Signature class instance and pass CertificateSearchOptions to it.

This example shows how to make advanced search for text data within the certificate documents.

var loadOptions = new LoadOptions()
{
    Password = "1234567890"
};

using (var signature = new Signature("certificate.pfx", loadOptions))
{
    var options = new CertificateSearchOptions()
    {
        // check the serial number
        Text = "AAD0D15C628A",
        // find exact math
        MatchType = TextMatchType.Contains,
    };

    // search for certificate data
    var result = signature.Search<MetadataSignature>(options);
    if (result.Count>0)
    {
        Console.WriteLine("\nCertificate contains following search results");
        foreach (MetadataSignature temp in result)
        {
            Console.WriteLine($"\t\t-{temp.Name} - {temp.Value}");
        }
    }
    else
    {
        Helper.WriteError("\nCertificate failed search process.");
    }
}
