About DUKPTCore

You'll find this library useful if you're working on financial services applications with the need to decrypt data using TDES (3DES, TDEA, triple-DES, etc) DUKPT (derived unique key per transaction), such as PIN or credit card account data.

DUKPTCore was adapted from sgbj's Dukpt.NET project and ported to .NET Standard.

Examples

Encrypting data:

string bdk = "0123456789ABCDEFFEDCBA9876543210";
string ksn = "FFFF9876543210E00008";
byte[] superSecretMessage = Encoding.UTF8.GetBytes("Hello World!");
byte[] encryptedData = DUKPT.Encrypt(bdk, ksn, superSecretMessage, DUKPTVariant.Data);

Decrypting data:

byte[] decryptedData = DUKPT.Decrypt(bdk, ksn, encryptedData, DUKPTVariant.Data);
string superSecretMessage = Encoding.UTF8.GetString(decryptedData); // Hello World!
