RUNJS CRACK LICENSE KEY
They're relatively simple, and they work great offline, but sometimes verifying that a license key is 'valid' isn't enough. Generating and verifying the authenticity of cryptographically signed license keys like this will work great for a lot of simple licensing needs. Verify the signature for the data using the public keyĬonst valid = verifier.verify(publicKey, signature, 'hex')
Then, to validate the license key within your Electron app, you would want to cryptographically 'verify' the key's authenticity by embedding the public (not the private!) key generated above into your application code base: // Split the license key's data and the signatureĬonst = licenseKey.split('.')Ĭonst data = om(encoded, 'base64').toString()Ĭonst verifier = crypto.createVerify('rsa-sha256') Using Node, that would look something like this: const crypto = require('crypto')Ĭonst ) their order number or an email address, and create a 'signature' of it using RSA cryptography. This can be done using cryptography, or it can be done by generating a 'random' license key string and storing it in a database and then building a CRUD licensing server that can verify that a given license key is "valid."įor cryptographic license keys, you can take some information from the customer, e.g. First, you would want to somehow generate a license key for each user. For most Electron apps, license keys will do just fine.Īdding license key (synonymous with product key) validation to an Electron app can be pretty straight forward. I previously would almost always recommended utilizing user accounts for licensing Electron apps, but I've since changed my position to be a little more nuanced. Edit for 2021: I'd like to revise this answer, as it has generated a lot of inquiries on the comparison I made between license keys and user accounts.
