# acryptohashnet
A pure managed C# implementation of cryptographic hash functions for .Net Standard 2.0 compatible platforms (.Net Framework, .Net Core, Mono, Xamarin, UWP, Unity).
[](https://www.nuget.org/packages/acryptohashnet)
[](https://www.nuget.org/packages/acryptohashnet)
# Features
* Pure managed C# implementation,
* Compatible with System.Security.Cryptography.HashAlgorithm and can be used everywhere as a simple drop replacement for the target hash algorithm,
* Extremely fast, highly optimized with low memory footprint (less GC time).
# Supported hash functions
* MD family: MD2, MD4, MD5,
* SHA family: SHA0, SHA1,
* SHA2 family: SHA224, SHA256, SHA384, SHA512,
* SHA3 family: SHA3-224, SHA3-256, SHA3-384, SHA3-512,
* RIPEMD family: RIPEMD128, RIPEMD160,
* Haval family: Haval128, Haval160, Haval192, Haval224, Haval256,
* Snefru, Snefru256,
* Tiger and Tiger2 (192 bits output)
# Usage examples
## MD5
``` csharp
using System;
using System.Linq;
using System.Text;
static class Program
{
static void Main(string[] args)
{
var message = "Test Message";
var hashAlgorithm = new acryptohashnet.MD5();
Console.WriteLine("MD5: {0}", hashAlgorithm.ComputeHash(message.ToUtf8Bytes()).ToHexString());
}
static byte[] ToUtf8Bytes(this string input) => Encoding.UTF8.GetBytes(input);
static string ToHexString(this byte[] input) => string.Join("", input.Select(x => x.ToString("x2")));
}
```
## SHA256 (SHA2-256 bits)
``` csharp
using System;
using System.Linq;
using System.Text;
static class Program
{
static void Main(string[] args)
{
var message = "Test Message";
var hashAlgorithm = new acryptohashnet.Sha2_256();
Console.WriteLine("SHA256: {0}", hashAlgorithm.ComputeHash(message.ToUtf8Bytes()).ToHexString());
}
static byte[] ToUtf8Bytes(this string input) => Encoding.UTF8.GetBytes(input);
static string ToHexString(this byte[] input) => string.Join("", input.Select(x => x.ToString("x2")));
}
```
## Compute string message hash via HashAlgorithm interface (MD5, SHA1, SHA256, SHA3-512)
``` csharp
static class Program
{
static void Main(string[] args)
{
var md5 = new acryptohashnet.MD5();
var sha1 = new acryptohashnet.SHA1();
var sha2_256 = new acryptohashnet.Sha2_256();
var sha3_512 = new acryptohashnet.Sha3_512();
var message = "Lorem ipsum is placeholder text commonly used in the graphic, " +
"print, and publishing industries for previewing layouts and visual mockups.";
Console.WriteLine("MD5: {0}", md5.ComputeHash(message.ToUtf8Bytes()).ToHexString());
Console.WriteLine("SHA1: {0}", sha1.ComputeHash(message.ToUtf8Bytes()).ToHexString());
Console.WriteLine("SHA256: {0}", sha2_256.ComputeHash(message.ToUtf8Bytes()).ToHexString());
Console.WriteLine("SHA3-512: {0}", sha3_512.ComputeHash(message.ToUtf8Bytes()).ToHexString());
}
static byte[] ToUtf8Bytes(this string input) => System.Text.Encoding.UTF8.GetBytes(input);
static string ToHexString(this byte[] input) => string.Join("", input.Select(x => x.ToString("x2")));
}
```
## Compute hash of file via HashAlgorithm interface (MD5, SHA1, SHA256, SHA3-512)
``` csharp
static class Program
{
static void Main(string[] args)
{
var md5 = new acryptohashnet.MD5();
var sha1 = new acryptohashnet.SHA1();
var sha2_256 = new acryptohashnet.Sha2_256();
var sha3_512 = new acryptohashnet.Sha3_512();
using (var file = File.OpenRead(@"C:\Windows\explorer.exe"))
{
Console.WriteLine("MD5: {0}", md5.ComputeHash(file).ToHexString());
file.Position = 0; // Rewind stream to beginning
Console.WriteLine("SHA1: {0}", sha1.ComputeHash(file).ToHexString());
file.Position = 0; // Rewind stream to beginning
Console.WriteLine("SHA256: {0}", sha2_256.ComputeHash(file).ToHexString());
file.Position = 0; // Rewind stream to beginning
Console.WriteLine("SHA3-512: {0}", sha3_512.ComputeHash(file).ToHexString());
}
}
static string ToHexString(this byte[] input) => string.Join("", input.Select(x => x.ToString("x2")));
}
