[Starting with the .NET Framework 4.5, Windows Identity Foundation (WIF) has been fully integrated into the .NET Framework. The version of WIF addressed by this topic, WIF 3.5, is deprecated and should only be used when developing against the .NET Framework 3.5 SP1 or the .NET Framework 4. For more information about WIF in the .NET Framework 4.5, also known as WIF 4.5, see the Windows Identity Foundation documentation in the .NET Framework 4.5 Development Guide.]

Encrypts a cookie using RSA.

Namespace: Microsoft.IdentityModel.Web
Assembly: Microsoft.IdentityModel (in Microsoft.IdentityModel.dll)

Usage

'Usage
Dim instance As RsaEncryptionCookieTransform

Syntax

'Declaration
Public Class RsaEncryptionCookieTransform
    Inherits CookieTransform

public class RsaEncryptionCookieTransform : CookieTransform

public ref class RsaEncryptionCookieTransform : public CookieTransform

public class RsaEncryptionCookieTransform extends CookieTransform

public class RsaEncryptionCookieTransform extends CookieTransform

Remarks

Cookies encrypted with this transform may be decrypted by any machine that shares the same RSA private key (generally associated with an X509 certificate).

The given data is encrypted using a random AES256 key. This key is then encrypted using RSA, and the RSA public key is sent in plain text so that when decoding the class knows which RSA key to use.
