The RSAPublicKey, token and the product id can be found on [this page](https://help.cryptolens.io/examples/key-verification). 15 | 16 | ```js 17 | const key = require('cryptolens').Key; 18 | const Helpers = require('cryptolens').Helpers; 19 | 20 | var RSAPubKey = "Your RSA Public key, which can be found here: https://app.cryptolens.io/User/Security"; 21 | var result = key.Activate(token="Access token with with Activate permission", RSAPubKey, ProductId=3349, Key="GEBNC-WZZJD-VJIHG-GCMVD", MachineCode=Helpers.GetMachineCode()); 22 | 23 | result.then(function(license) { 24 | 25 | // success 26 | 27 | // Please see https://app.cryptolens.io/docs/api/v3/model/LicenseKey for a complete list of parameters. 28 | console.log(license.Created); 29 | 30 | }).catch(function(error) { 31 | // in case of an error, an Error object is returned. 32 | console.log(error.message); 33 | }); 34 | ``` 35 | 36 | ### Offline activation (saving/loading licenses) 37 | Assuming the license key verification was successful, we can save the result in a file so that we can use it instead of contacting Cryptolens. 38 | 39 | First, we need to add the reference to the helper methods: 40 | 41 | ```js 42 | const Helpers = require('cryptolens').Helpers; 43 | ``` 44 | 45 | We can now proceed and save it as a string. 46 | 47 | ```js 48 | var licenseString = Helpers.SaveAsString(license); 49 | ``` 50 | 51 | When loading it back, we can use the code below: 52 | ```js 53 | var license = Helpers.LoadFromString(RSAPubKey, licenseString); 54 | ``` 55 | 56 | If you want to make sure that the license file is not too old, you can specify the maximum number of days as shown below (after 30 days, this method will return null). 57 | ```js 58 | var license = Helpers.LoadFromString(RSAPubKey, licenseString, 30); 59 | ``` 60 | 61 | -------------------------------------------------------------------------------- /internal/HelperMethods.js: -------------------------------------------------------------------------------- 1 | const got = require("got"); 2 | module.exports = class HelperMethods { 3 | 4 | /** 5 | * Verify that a response obtained from Key.Activate has not been tampered with. 6 | * @param {object} response 7 | * @param {string} rsaPubKey 8 | */ 9 | static VerifySignature(response, rsaPubKey) { 10 | const NodeRSA = require('node-rsa'); 11 | const key = new NodeRSA(); 12 | const pubKey = HelperMethods.GetPublicKeyParams(rsaPubKey); 13 | key.importKey({ n: pubKey.modulus, e: pubKey.exponent }, 'components-public'); 14 | return key.verify(Buffer.from(this.GetValueCaseInsensitive(response,"licenseKey"), "base64"), Buffer.from(this.GetValueCaseInsensitive(response,"signature"), "base64")); 15 | } 16 | 17 | /** 18 | * Returns a dictionary with the modulus and exponent obtained from an RSA Public key string. 19 | */ 20 | static GetPublicKeyParams(str) { 21 | 22 | const modulus_str = str.substring(str.indexOf('') + 8, str.indexOf('')); 23 | const exponent_str = str.substring(str.indexOf('') + 9, str.indexOf('')); 24 | 25 | return { 26 | modulus: new Buffer.from(modulus_str, 'base64'), 27 | exponent: new Buffer.from(exponent_str, 'base64') 28 | } 29 | } 30 | 31 | static CallAPI(url, formBody) { 32 | return new Promise((resolve, reject) => { 33 | (async () => { 34 | try { 35 | const body = await got.post(url, { 36 | form: formBody 37 | }).json(); 38 | 39 | if (body.result === 1) { 40 | reject(new Error(body.message)); 41 | } else { 42 | resolve(body); 43 | } 44 | } catch(error){ 45 | if (error.name === "HTTPError") { 46 | try { 47 | reject(new Error(JSON.parse(error.response.body).message)); 48 | } catch (e) { 49 | reject(new Error("Could not parse the error message returned from the server.
