Berrysoft.XXTea

A .NET implementation of TEA, XTEA and XXTEA algorithm.

Usage

var cryptor = new XXTeaCryptor("SuperStrongKey");
var encryptedData = cryptor.EncryptString("Hello world!"); // Encrypt
var decryptedData = cryptor.DecryptString(encryptedData); // Decrypt

Benchmark

The other two XXTEA implementation:

• Gibbed.XXTEA
• xxtea-dotnet

Speed

Encrypt Time	Decrypt Time

Berrysoft.XXTea is slightly slower than Gibbed.XXTEA, mostly because of virtual function calls.

Allocation

Encrypt Allocation	Decrypt Allocation

Berrysoft.XXTea uses less allocation, and even no allocation with data in Span.
