Properties

	Name	Description
	KeyExchangeAlgorithm	When overridden in a derived class, gets the name of the key exchange algorithm. (Inherited from AsymmetricAlgorithm.)
	KeySize	Gets or sets the size, in bits, of the key modulus used by the asymmetric algorithm. (Inherited from AsymmetricAlgorithm.)
	LegalKeySizes	Gets the key sizes that are supported by the asymmetric algorithm. (Inherited from AsymmetricAlgorithm.)
	SignatureAlgorithm	Gets the name of the signature algorithm. (Inherited from AsymmetricAlgorithm.)

Methods

	Name	Description
	Clear	Releases all resources used by the AsymmetricAlgorithm class. (Inherited from AsymmetricAlgorithm.)
	Create()	Creates an instance of the default implementation of the RSA algorithm.
	Create(String)	Creates an instance of the specified implementation of RSA.
	DecryptValue	When overridden in a derived class, decrypts the input data using the private key.
	Dispose()	Releases all resources used by the current instance of the AsymmetricAlgorithm class. (Inherited from AsymmetricAlgorithm.)
	Dispose(Boolean)	Releases the unmanaged resources used by the AsymmetricAlgorithm class and optionally releases the managed resources. (Inherited from AsymmetricAlgorithm.)
	EncryptValue	When overridden in a derived class, encrypts the input data using the public key.
	Equals(Object)	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	ExportParameters	When overridden in a derived class, exports the RSAParameters.
	Finalize	Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	FromXmlString	Initializes an RSA object from the key information from an XML string. (Overrides AsymmetricAlgorithm.FromXmlString(String).)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	ImportParameters	When overridden in a derived class, imports the specified RSAParameters.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	ToXmlString	Creates and returns an XML string containing the key of the current RSA object. (Overrides AsymmetricAlgorithm.ToXmlString(Boolean).)

Fields

	Name	Description
	KeySizeValue	Represents the size, in bits, of the key modulus used by the asymmetric algorithm. (Inherited from AsymmetricAlgorithm.)
	LegalKeySizesValue	Specifies the key sizes that are supported by the asymmetric algorithm. (Inherited from AsymmetricAlgorithm.)

Remarks

Extending this class proves that you are implementing an RSA key. This is required for any developer providing a new RSA key implementation.

The only purpose of this class is as a hierarchy member for identification of the RSA algorithm.

 In Silverlight for Windows Phone, the RSACryptoServiceProvider supports key lengths from 384 bits to 4800 bits in increments of 8 bits.

Version Information

Silverlight for Windows Phone

Supported in: Windows Phone OS 7.1

Platforms

For a list of the operating systems and browsers that are supported by Silverlight, see Supported Operating Systems and Browsers.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
