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

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.
