Methods

  Name Description
Public methodSupported by Silverlight for Windows Phone Clear Releases all resources used by the AsymmetricAlgorithm class. (Inherited from AsymmetricAlgorithm.)
Public methodStatic memberSupported by Silverlight for Windows Phone Create() Creates an instance of the default implementation of the RSA algorithm.
Public methodStatic memberSupported by Silverlight for Windows Phone Create(String) Creates an instance of the specified implementation of RSA.
Public methodSupported by Silverlight for Windows Phone DecryptValue When overridden in a derived class, decrypts the input data using the private key.
Public methodSupported by Silverlight for Windows Phone Dispose() Releases all resources used by the current instance of the AsymmetricAlgorithm class. (Inherited from AsymmetricAlgorithm.)
Protected methodSupported by Silverlight for Windows Phone Dispose(Boolean) Releases the unmanaged resources used by the AsymmetricAlgorithm class and optionally releases the managed resources. (Inherited from AsymmetricAlgorithm.)
Public methodSupported by Silverlight for Windows Phone EncryptValue When overridden in a derived class, encrypts the input data using the public key.
Public methodSupported by Silverlight for Windows Phone Equals(Object) Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Public methodSupported by Silverlight for Windows Phone ExportParameters When overridden in a derived class, exports the RSAParameters.
Protected methodSupported by Silverlight for Windows Phone 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.)
Public methodSupported by Silverlight for Windows Phone FromXmlString Initializes an RSA object from the key information from an XML string. (Overrides AsymmetricAlgorithm.FromXmlString(String).)
Public methodSupported by Silverlight for Windows Phone GetHashCode Serves as a hash function for a particular type. (Inherited from Object.)

Protected methodSupported by Silverlight for Windows Phone MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
Public methodSupported by Silverlight for Windows Phone ToString Returns a string that represents the current object. (Inherited from Object.)
Public methodSupported by Silverlight for Windows Phone ToXmlString Creates and returns an XML string containing the key of the current RSA object. (Overrides AsymmetricAlgorithm.ToXmlString(Boolean).)

Fields

  Name Description
Protected fieldSupported by Silverlight for Windows Phone KeySizeValue Represents the size, in bits, of the key modulus used 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.

Silverlight for Windows Phone 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

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.
