RsaEncryptionCookieTransform Class

Definition

Namespace:

System.IdentityModel

Assembly:

System.IdentityModel.dll

Encrypts a cookie using RSA.

public ref class RsaEncryptionCookieTransform : System::IdentityModel::CookieTransform

public class RsaEncryptionCookieTransform : System.IdentityModel.CookieTransform

type RsaEncryptionCookieTransform = class
    inherit CookieTransform

Public Class RsaEncryptionCookieTransform
Inherits CookieTransform

Inheritance

Object

CookieTransform

RsaEncryptionCookieTransform

Remarks

Cookies encrypted with this transform may be decrypted by any computer that shares the same RSA private key (generally associated with an X.509 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.

Important

When using the RsaEncryptionCookieTransform with a service, if a key provided by a certificate changes the service must be restarted.

Constructors

RsaEncryptionCookieTransform(RSA)	Initializes a new instance of the RsaEncryptionCookieTransform class that uses the specified key for encryption and decryption.
RsaEncryptionCookieTransform(X509Certificate2)	Initializes a new instance of the RsaEncryptionCookieTransform class that uses the private key of the specified X.509 certificate for encryption and decryption.

Properties

DecryptionKeys	Gets the keys used for decryption By default, this property returns a list that contains only the encryption key.
EncryptionKey	Gets or sets the RSA key used for encryption.
HashName	Gets or sets the name of the hash algorithm to use.

Methods

Decode(Byte[])	Decrypts the specified data by using the provided RSA key(s) to decrypt an AES key, which decrypts the cookie.
Encode(Byte[])	Encodes the specified data. The data is encrypted using the default encryption algorithm (AES-256), then the AES key is encrypted using RSA and the RSA public key is appended.
Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetType()	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
ToString()	Returns a string that represents the current object. (Inherited from Object)
