问题 I'm trying to hash a variable in NodeJS like so: var crypto = require('crypto'); var hash = crypto.createHash('sha256'); var code = 'bacon'; code = hash.update(code); code = hash.digest(code); console.log(code); But looks like I have misunderstood the docs as the console.log doesn't log a hashed version of bacon but just some information about SlowBuffer. What's the correct way to do this? 回答1: base64: const hash = crypto.createHash('sha256').update(pwd).digest('base64'); hex: crypto

问题 There's this function in the NPM cuid library: import * as crypto from "crypto" var lim = Math.pow(2, 32) - 1; export function getRandomValue () { return Math.abs(crypto.randomBytes(4) .readInt32BE(0) / lim) } The return value from this should not return values with dashes in it. However per my test sampling a million values, one value returned contains a dash. How do we eliminate the dashes? Someone in an earlier question suggested using % instead of / and this works. I ran 10 million

问题 I am using nodeJS Crypto Module to encrypt password. Sample code: crypto.pbkdf2Sync(password, salt, 200, 64).toString('base64'); But I am not sure, whenever I call this method, following error shown TypeError: Object # has no method 'pbkdf2Sync' Please let me know what is the issues Thanks all 回答1: pbkdf2Sync was added to the Crypto module in version 0.9.3. You can either upgrade your installation of Node to 0.9.3 or higher, or you can use the asynchronous version of the function, crypto

问题 I am trying to figure out how to salt and hash a password in nodejs using the crypto module. I am able to create the hashed password doing this: UserSchema.pre('save', function(next) { var user = this; var salt = crypto.randomBytes(128).toString('base64'); crypto.pbkdf2(user.password, salt, 10000, 512, function(err, derivedKey) { user.password = derivedKey; next(); }); }); However I am confused about how to later validate the password. UserSchema.methods.validPassword = function(password) { /

问题 I'm trying to generate SHA256 and HmacSHA512 hashes on a device which unfortunately has no support for the standard Node crypto library. So I am adjusting the code to use CryptoJS instead. However, CryptoJS cannot encode the Hash as in binary (only Hex, Base64 and Latin1 are available encoders). Below is the function I'm trying to migrate. Previous (unusable) code is commented out. const getMessageSignature = (path, request, secret, nonce) => { // Expected outcome: // API-Sign = Message
