Here are the basic steps to creating a unique key:
- First, all input parameters of the environment are serialized into a byte array, and a seed is randomly obtained.
- An encryption key is created based on the input parameters and the seed value.
- At this stage, an encryptor is created that associated to the environment.
- Next, the data, as well as the expiration date, is then serialized.
- A byte array is created that contains the serialized data.
- The source data is encrypted using the selected encryption algorithm.
- A hash of the original data and seed value is created using the selected hashing function.
- Finally, a new instance of the ActivationKey is created that contains the encrypted data, the calculated hash, and a random seed value that is used to generate the key.
The key consists of several parts, separated by a special symbol to facilitate parsing, the meaning of which is hidden from the end user and understandable only to the application. The table below shows the name and purpose of these parts.
| Part | Description |
|---|---|
| Data | Content of encrypted expiration date and application data (optional). This embedded data can be recovered after successful key verification. |
| Hash | Checksum of key expiration date, encrypted application data, and environment identifiers. Ensures the validity of the key during verification. |
| Seed | The initialization value that was used to encrypt the data. Allows to generate unique keys every time to increase cryptographic strength. |
