In whatever persistence mechanism (database) you’re using, you would store the resulting hash alongside the salt and number of iterations, both of which would be plaintext. If each password uses different salt (which you should do), you must also save that information. You would then compare the new plain text password, hash that using the … Read more
nodejs v10.12 now supports this natively with crypto.generateKeyPair const { generateKeyPair } = require(‘crypto’); generateKeyPair(‘rsa’, { modulusLength: 4096, publicKeyEncoding: { type: ‘spki’, format: ‘pem’ }, privateKeyEncoding: { type: ‘pkcs8’, format: ‘pem’, cipher: ‘aes-256-cbc’, passphrase: ‘top secret’ } }, (err, publicKey, privateKey) => { // Handle errors and use the generated key pair. });
You can use the crypto module: var crypto = require(‘crypto’); var assert = require(‘assert’); var algorithm = ‘aes256’; // or any other algorithm supported by OpenSSL var key = ‘password’; var text=”I love kittens”; var cipher = crypto.createCipher(algorithm, key); var encrypted = cipher.update(text, ‘utf8’, ‘hex’) + cipher.final(‘hex’); var decipher = crypto.createDecipher(algorithm, key); var decrypted = … Read more
