The biggest challenge here is that the classical public key algorithms have large signature sizes.

A license key would look like this: BASE32(CONCAT(DATA, PRIVATE_KEY_ENCRYPTED(HASH(DATA)))) This way, even if someone has full access to your product's logic, they cannot generate license keys because they don't have the private key. The product should validate the license keys with the corresponding public key. The signatures should be part of the license key. Your license keys should be in fact signed "documents", containing some useful data, signed with your company's private key. The answer is simple but technically challenging: digital signatures using public key cryptography. Your support department would thank you for this, and you will have lower costs in this area. You don't want every customer calling the technical support because they don't understand if the key contains a "l" or a "1". If your product is successful, someone will make a key generator in a matter of days from release.Ī license key should be useable on only one computer (or at least you should be able to control this very tightly)Ī license key should be short and easy to type or dictate over the phone. Obfuscating the algorithm or hiding an encryption key within your software is really out of the question if you are serious about controlling licensing. Only your company should be able to generate license keys for your products, even if someone completely reverse engineers your products (which WILL happen, I speak from experience). Ideally, you would want your license keys to have the following properties: And it's a pity, because for companies, license keys have almost the same value as real cash. It is possible that the temporary license key request might not be approved.There are many ways to generate license keys, but very few of those ways are truly secure.

If a second set of temporary license keys is needed, the customer needs to send an email to stating the reason why a second temporary key should be granted as well as the customer's contact information, contract number (if known), company name, customer number, system serial number, processor group, product, and operating system release.

This service is limited to one time per serial number per year. Temporary License Keys: A temporary set of license keys might be issued in emergency circumstances. If the version is 7 or below, they need to provide the model number, serial number, and user count. If the customer has Showcase V8 or above, they need to provide their authorization code to Client Care. The Client Care team does not operate 24 hours a day. PMRs that come in requesting license keys for Showcase products should be routed to the Showcase Client Care team at BACSR,19F. Showcase uses its own license key generator.
Showcase product license keys: Generating license keys for Showcase products is not handled by the IBM Global Support Center or the License Key Center. License Keys for Third-Party Software: In general, assistance with planning, ordering, and retrieving these keys should be pursued directly with the third party or an IBM Business Partner.
