TripleDESCryptoServiceProvider Class

Definition

Namespace:
System.Security.Cryptography
Assembly:
mscorlib.dll
Assembly:
netstandard.dll

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

Remarks

TripleDESCryptoServiceProvider is obsolete. Use the TripleDES.Create() method instead.

Note

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