Tiny utilily encrypting/decrypting texts/objects to/from base64 strings
Interfaces
This nuGet has only one public class implementing the following interface
ICrypto
using System;
using System.Threading.Tasks;
namespace pvWay.Crypto.Core
{
public interface ICrypto: IAsyncDisposable, IDisposable
{
Task<string> EncryptAsync(string text);
Task<string> EncryptAsync<T>(T data) where T: class;
Task<string> EncryptEphemeralAsync(string text, TimeSpan? validity = null);
Task<string> EncryptEphemeralAsync<T>(T data, TimeSpan? validity = null) where T : class;
Task<string> DecryptAsync(string base64String);
Task<T> DecryptAsync<T>(string base64String) where T: class;
Task<T> DecryptEphemeralAsync<T>(string b64Str);
}
}
Usage
See here after a short Console that use the pool
The code
using System;
using pvWay.Crypto.Core;
namespace CryptoConsole
{
internal static class Program
{
private const string InitializationVectorString = "0123456789ABCDEF";
private const string KeyString = "123456789 123456789 123456789 12";
private static void Main(/*string[] args*/)
{
var crypto = new Crypto(
KeyString,
InitializationVectorString,
TimeSpan.FromSeconds(10));
var b64 = crypto.EncryptAsync("test").Result;
Console.WriteLine(b64);
var text = crypto.DecryptAsync(b64).Result;
Console.WriteLine(text);
var mc = new MyClass
{
TheHeader = "header",
TheBody = "Body",
TheFooter = "Footer"
};
b64 = crypto.EncryptAsync(mc).Result;
Console.WriteLine(b64);
var mcBack = crypto.DecryptAsync<MyClass>(b64).Result;
Console.WriteLine(mcBack.TheHeader);
Console.WriteLine(mcBack.TheBody);
Console.WriteLine(mcBack.TheFooter);
b64 = crypto.EncryptEphemeralAsync(mc, TimeSpan.FromSeconds(15)).Result;
mcBack = crypto.DecryptEphemeralAsync<MyClass>(b64).Result;
Console.WriteLine(mcBack.TheBody + "is still valid");
}
private class MyClass
{
public string TheHeader { get; set; }
public string TheBody { get; set; }
public string TheFooter { get; set; }
}
}
}
Happy coding
