Re: RSACryptoServiceProvider

Ok!

I'm new to this ASP.NET stuff - so, how do I grant the application more
permissions - it's a "code-behind" ASP thingy so I can't use the
snap-in or...

That error message probably means your code doesn't have the Code Access
Security permissions required to read the private key... check out the .Net
Framework 2.0 Config snapin to evaluate your assembly to see which
permissions you get granted, and whether you need to grant your code more
security permissions.

This is the permission you need for your code:
System.Security.Permissions.KeyContainerPermission

I'm trying this out usig ASP 2.0.
The public key part works ok but the private key request fails.

CspParameters cspParams = new CspParameters();
cspParams.Flags = CspProviderFlags.UseMachineKeyStore;
RSACryptoServiceProvider rsa = new
RSACryptoServiceProvider(cspParams);
rsa.PersistKeyInCsp = false;
string publickey = rsa.ToXmlString(false);
string privatekey = rsa.ToXmlString(true);
