Question

Is it possible to store an X509Certificate2 in a SQL Server table rather than pull a .p12 file from the file system? I’m sure you can but not sure how to go about this.

Answer 1

This is definitely possible, the X509Certificate2 has a RawData property that can be saved into your SQL Database. To reconstruct the certificate you can use this constructor

var cert = new X509Certificate2(filename);
var data = cert.RawData;

// save data to database...

// Fetch data from database...

cert = new X509Certificate2(data);
