RC2CryptoServiceProvider Class

Updated: February 2009

Defines a wrapper object to access the cryptographic service provider (CSP) implementation of the RC2 algorithm. This class cannot be inherited.

Namespace:  System.Security.Cryptography
Assembly:  mscorlib (in mscorlib.dll)
[ComVisibleAttribute(true)]
public ref class RC2CryptoServiceProvider sealed : public RC2

The RC2CryptoServiceProvider implementation supports key lengths from 40 bits to 128 bits in increments of 8 bits.

The RC2CryptoServiceProvider object is a block cipher that encrypts and decrypts data in blocks of 8 bytes. This class pads the final block of data if it is less than 8 bytes. As a result of this padding, the length of encrypted data could be greater than the original plaintext.

Note that the RC2CryptoServiceProvider object does not use salt.

NoteNote:

A newer symmetric encryption algorithm, Advanced Encryption Standard (AES), is available. Consider using the AesCryptoServiceProvider class instead of the RC2CryptoServiceProvider class.

The following code example encrypts and then decrypts a string.

No code example is currently available or this language may not be supported.
