SoftLicense

SoftLicense is a javascript library for generating software licenses and checking them in your code.

Installation

npm install softlicense -g
npm install softlicense --save

Usage

Generate a license

Read the manual by executing

softlicense-cli

Minimal execution for endless license for MyModule

softlicense-cli --action generate --moduleName MyModule

Check a license (CLI)

softlicense-cli --action check --moduleName testmodule --license ...

Check a license (programmatically)

function MyModule(license) {
    var checker = new Checker('0g28MGcyOGN3Y3g3NzZTNzc2Vjc3Nk83NzZkNzc2UTc3NjA3NzZDNzc2MA==cwcx', license);

    this[checker.decryptFunction(
        '09e1MDllMWkzZ3Q3NytXNzcraDc3K1I3NytnNzcrNjc3K2s3NytrNzcrNDc3K0I3Nytqi3gt')] =
        function () {
            if (!checker.isModuleLicensed('myfunction')) {
                console.warn('myfunction has not been licensed');
                return;
            }
            alert('myfunction');
        };

    this[checker.decryptFunction(
        '04rnMDRybmVyaTA3NytINzcrKzc3K1Q3Nys4Nzcrazc3K3Q3NytYNzcr' +
        'NTc3K2M3Nyt1NzcrTDc3Kys3Nys4NzcrMjc3KzQ3Nyt1NzcrTw==eri0')] =
        function () {
            if (!checker.isModuleLicensed('myfunctionInvalid')) {
                console.warn('myfunctionInvalid has not been licensed');
                return;
            }
            alert('myfunctionInvalid');
        };

    if (checker.isLicenseValid()) {
        return {
            myfunction: this[checker.decryptFunction(
                '0c7xMGM3eHU0eHA3NytXNzcraDc3K1I3Nytn' +
                'NzcrNjc3K2s3NytrNzcrNDc3K0I3Nytqu4xp')],
            myfunctionInvalid: this[checker.decryptFunction(
                '0r9mMHI5bWpnOWI3NytINzcrKzc3K1Q3Nys4Nzcrazc3K3Q3NytYNzcr' +
                'NTc3K2M3Nyt1NzcrTDc3Kys3Nys4NzcrMjc3KzQ3Nyt1NzcrTw==jg9b')]
        };
    } else {
        console.warn('MyModule has not been licensed or license is invalid');
    }
}

Crypt a function internally

First crypt the function

softlicense-cli --action crypt --moduleName MyModule --input myFunction

Then use the function like this

var checker = new Checker(privateKey, license);
this[checker.decryptFunction(cryptedFunctionString)]()

Usage no npm install needed!
