licence-key-generator

This program was created for a license key generation and validation.

How to use

There is 2 variants: right from the code or generate a jar and use it

1. Run right from the code (all scripts lie in a root folder to have an access to build.sbt)
   1. To generate a key run ./generateKey.sh <domain> <date>. Date must have the following format dd-mm-yyyy
   2. To validate a key run ./validateKey.sh <key>. After it you will see a corresponding result as a message
   3. To test a program - run sbt test
2. Through a jar file
   1. Run sbt proguard in a root folder. It will generate 2 jar files - licence-key-encoded.jar and licence-key.jar in a ./jar folder.. The first one is encoded by progurard so you should use it. It will run tests too.
   2. Open a terminal in a ./jar folder.
   3. Use the same scripts as in the previous variant. Everything is the same.
   4. To test a program - run sbt test
