pclcrypto

pclcrypto is a library that provides cryptographic functionality for portable class libraries (PCL) in .NET. It allows developers to perform various cryptographic operations such as encryption, decryption, hashing, and key generation.

Example: Encrypting and Decrypting Data

Here’s an example of how to use pclcrypto to encrypt and decrypt data:


    using PCLCrypto;

    public class CryptoExample
    {
        public static void Main()
        {
            string originalData = "Hello, world!";
            byte[] encryptedData;
            byte[] decryptedData;

            // Generate a random symmetric key
            var key = WinRTCrypto.SymmetricKeyAlgorithmProvider.OpenAlgorithm(SymmetricAlgorithm.AesCbcPkcs7).CreateSymmetricKey();

            // Encrypt the data
            using (var encryptor = WinRTCrypto.CryptographicEngine.CreateEncryptor(key, null))
            {
                encryptedData = encryptor.Encrypt(Encoding.UTF8.GetBytes(originalData));
            }

            // Decrypt the data
            using (var decryptor = WinRTCrypto.CryptographicEngine.CreateDecryptor(key, null))
            {
                decryptedData = decryptor.Decrypt(encryptedData);
            }

            string decryptedText = Encoding.UTF8.GetString(decryptedData);

            Console.WriteLine(decryptedText); // Output: Hello, world!
        }
    }

In this example, we first generate a random symmetric key using AES encryption algorithm in Cipher Block Chaining (CBC) mode with PKCS7 padding. Then, we encrypt the original data (in this case, the string “Hello, world!”) using the generated key. Finally, we decrypt the encrypted data back to its original form.

This is just a simple example to demonstrate the basic usage of pclcrypto. The library provides various other cryptographic algorithms and functionalities that you can explore based on your specific needs.
