SEL - SeriosuBit Ellipter, is a powerful yet easy to use 100% managed .NET library for licensing applications using user friendly and secure license keys based on asymmetric elliptic curves encryption.
SEL UI – SEL User Interface is an executable program which helps you to create Public/Private Keys, generate and validate serials.
A developer key is a serial which you get when buying our SEL. Once you get this key you can use our licensing system without trial limitation.
A trial key is similar to developer key, but with one essential limitation � you can use SEL only on your computer and you can�t distribute your software if protected with SEL and that trial key.
5. Where can I get a trial key?
From our web page http://seriousbit.com/GetTrialKey/
6. What are Public and Private Key?
1. Public key is a string used to verify a serial. It can�t be used to generate a serial or to calculate the private key.
Ex:

2. Private key is a string used to create a serial. You need to keep it in sescret, and don�t put it in your code � if a hacker will reverse your code and get your private key then he can create a Keygen very easy.
7. Where do I get a Public or Private Key?
You can create an unlimited count of Public/Private keys with SEL UI – just press the button “Generate Keys”.
8. Could someone create a Keygen using my Private Key?
Yes.
9. Could someone create a Keygen using my Public key?
No.
10. How can I create a serial?
There are two methods to create a serial: manually and from code, using SerialsManager class.
a) Manually, using SEL UI - Open SEL UI from Start>Programs>SeriosuBit Licensing, press �Generate Keys� button to create public/private keys pars and press �Generate Serials�.
b) Programmatically - Code example:

11. Why generated serials are so long?
The minimal serial length is 29 characters, without delimiters. If your created serials are too long then this mean that you’re using a too long “Product Info” – try to minimize it.
12. How can I get serial’s ID and Product Info?
There are two methods
a. Manually, using SEL UI � paste your Public Key in �Public Key� textbox, paste the serial in �Serials Validator� text box and click button �Validate Serial�.
b. Programmatically:

13. Could I make trials using Ellipter?
Yes, Ellipter supports two trial types - time limited and uses count limited trials. Also it is possible to combine them. See Ellipter integrated documentation for examples.
