# IntelliLock.LicenseManager.dll

- IntelliLock.LicenseManager enables you to:

Open IntelliLock project files
Create license files
Read license files
Easily encrypt and sign data using the master key stored in your project file (asymmetric encryption techniques are used here)
Easily decrypt data and verify its signature using the master key stored in your project file (asymmetric encryption techniques are used here)
Generate a reactivation code for invalidated license files

- You can freely use this library on a server or any other environment.

1. Open IntelliLock Project
2. Create License File
3. Create License File
4. Create Hardware Locked License File
5. Read License File
6. Read License File
7. Generate Reactivation Code
8. Encrypt And Sign Data
9. Verify Signature
10. Decrypt Data
