This ASP.NET Security tutorial explains how to use the .NET ICryptoTransform interface in C#.
The ICryptoTransform interface represents blockwise cryptographic transformation which could be an encryption, ecryption, hashing, Base64 encoding/decoding, or formatting operation. You can create an ICryptoTransform object for a given algorithm by using the:
- CreateEncryptor() method – if you want to encrypt data.
- CreateDecryptor() method – if you want to encrypt data.
The next code lines illustrate this approach:
TripleDES crypt = TripleDES.Create();
ICryptoTransform transform = crypt.CreateEncryptor();
