WebThe CryptoStream class is another composable stream that enables an application to encrypt and decrypt data to and from another stream. This class is located in the System.Security.Cryptography namespace. To use this class effectively, you need to understand cryptography, which is beyond the scope of this book.

WebMar 1, 2015 · Rather than converting to byte[] as an intermediate step when passing to different stream objects you can chain multiple streams together, passing the output from one to the input of another.. This approach makes sense here, as you are chaining together. Binary Serialization => Encryption => Writing to File.. With this in mind, you can change … WebNov 21, 2024 · Step 1: The first step would be to create a C# file in the IDE of your choice or you can just use the GeeksForGeeks IDE. Name the Class “GFGEncryption” to keep things simple and aligned with the tutorial. Step 2: Now make a new method named encodeString ( ) which takes no parameters and returns a string.
