title: Store a RsaSecurityKey in DB
body: <p>How can I store an object of class RsaSecurityKey <a href="https://msdn.microsoft.com/en-us/library/system.identitymodel.tokens.rsasecuritykey(v=vs.110).aspx" rel="nofollow noreferrer">https://msdn.microsoft.com/en-us/library/system.identitymodel.tokens.rsasecuritykey(v=vs.110).aspx</a> in a relational database (like Postgres)?</p>
  
  <p>I have to create RsaSecurityKey (first time) and store the key in db and use it in Identity Server (using IdentityServer4 library) for signing Jwt tokens.</p>
