RSA Class

July 28, 2014

Represents the base class from which all implementations of the RSA algorithm inherit.

Namespace:  System.Security.Cryptography
Assembly:  mscorlib (in mscorlib.dll)

public abstract class RSA : AsymmetricAlgorithm

The RSA type exposes the following members.

  NameDescription
Protected methodRSAInitializes a new instance of RSA.
Top

  NameDescription
Public methodClear (Inherited from AsymmetricAlgorithm.)
Public methodStatic memberCreate()Creates an instance of the default implementation of the RSA algorithm.
Public methodStatic memberCreate(String)Creates an instance of the specified implementation of RSA.
Public methodDecryptValueWhen overridden in a derived class, decrypts the input data using the private key.
Public methodDispose() (Inherited from AsymmetricAlgorithm.)
Protected methodDispose(Boolean) (Inherited from AsymmetricAlgorithm.)
Public methodEncryptValueWhen overridden in a derived class, encrypts the input data using the public key.
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Public methodExportParametersWhen overridden in a derived class, exports the RSAParameters.
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
Public methodFromXmlStringInitializes an RSA object from the key information from an XML string. (Overrides AsymmetricAlgorithm.FromXmlString(String).)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodImportParametersWhen overridden in a derived class, imports the specified RSAParameters.
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)
Public methodToXmlStringCreates and returns an XML string containing the key of the current RSA object. (Overrides AsymmetricAlgorithm.ToXmlString(Boolean).)

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

Windows Phone OS

Supported in: 8.1, 8.0, 7.1

Windows Phone

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