Step 1
Find bin\CommonLibrary.dll under installation directory, decompile class CommonLibrary.Activation.ActivationLogic then extract function EncryptInRC2 and all the consts.
Step 2
Put EncryptInRC2 , other consts and the following code into the same class:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 |
internal static string Encrypt(string machine_id, string date) { string s = machine_id // Disk serial + date // Issue date + "0"; // TrialTerm: If ExpiredCode is "1", then this license will be revoked after TrialTerm*10 days byte[] arr1 = EncryptInRC2(s); byte[] hash = SHA1.Create().ComputeHash(arr1); DSACryptoServiceProvider cryptoServiceProvider = new DSACryptoServiceProvider(512); cryptoServiceProvider.FromXmlString(PUBLIC_KEY); DSASignatureFormatter dsf = new DSASignatureFormatter(cryptoServiceProvider); dsf.SetHashAlgorithm("SHA1"); byte[] SignedHash = dsf.CreateSignature(hash); MemoryStream m = new MemoryStream(); m.Write(arr1, 0, arr1.Length); m.Write(SignedHash, 0, SignedHash.Length); string result = "0" // ExpiredCode + Convert.ToBase64String(m.ToArray()); // Encrypted code m.Dispose(); return result; } |
Step 3
Invoke Encrypt with the first argument being serial number displayed on registration window (8-digit HEX disk serial like 1234ABCD), and the second argument being a 6-digit date string no later than today in the format of "yyMMdd" . Return value is the registration code.
