Basically, for a customer with a valid license key, you need to generate some "activation data" which is a signed message embedding the computer's hardware id as the signed data. This is achievable by product activation (Windows is a good example).
You can further reduce the signature sizes using algorithms like the Schnorr digital signature algorithm (patent expired in 2008 - good :) ) ECC keys are like 6 times shorter than RSA keys, for the same strength. One of the most powerful approaches is to use elliptic curve cryptography (with careful implementations to avoid the existing patents). You don't want your license keys to have hundreds of characters. 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. Filter Forge's custom memory manager allows it to render large bitmaps – up to 65536圆5536 pixels – even on moderate amounts of RAM.There are many ways to generate license keys, but very few of those ways are truly secure. A high-precision floating-point rendering pipeline allows Filter Forge to support 16- and 32-bit image modes and eliminates unwanted artifacts such as color banding. For end-users, the filter internals are hidden behind a simple set of filter controls – anyone can immediately benefit from filters without knowing what is inside them.įilter Forge's rendering engine takes full advantage of multi-core processors – for example, a dual-core processor can speed the rendering up to 96%. Components include familiar operations such as blurs, gradients, color adjustments, distortions, and blending. Filters are assembled by connecting components into a network to combine their effects. The key feature of Filter Forge is the Filter Editor, a visual node-based environment allowing users to build custom filters without writing a single line of code. Also, filters can automatically generate diffuse, specular, bump, and normal maps, which makes Filter Forge an essential tool for artists creating 3D models and environments, architectural visualization and high-end game content. All filters are adjustable and editable, seamlessly tiled, resolution-independent, and support real-world HDRI lighting. Filter Forge can work as a Photoshop plugin or a standalone application.įilter Forge can produce a wide range of textures and effects which include organic structures, metallic and rocky surfaces, distortions, abstract textures, repeating patterns, color corrections, and more.
