System.Security.Cryptography.TripleDESCryptoServiceProvider Class

Defines a wrapper object to access the cryptographic service provider (CSP) version of the System.Security.Cryptography.TripleDES algorithm. This class cannot be inherited.

public sealed class TripleDESCryptoServiceProvider : TripleDES


This algorithm supports key lengths from 128 bits to 192 bits in increments of 64 bits.


A newer symmetric encryption algorithm, Advanced Encryption Standard (AES), is available. Consider using the System.Security.Cryptography.AesCryptoServiceProvider class instead of the System.Security.Cryptography.TripleDESCryptoServiceProvider class. Use System.Security.Cryptography.TripleDESCryptoServiceProvider only for compatibility with legacy applications and data.
