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 AesCryptoServiceProvider class instead of the class.
The following code example creates a object and uses it to encrypt and decrypt data in a file.
