Using the following node js: var crypto = require('crypto'); var encrypt = function (input, password, callback) { var m = crypto.createHash('md5'); m.update(password); var key = m.digest('hex'); m = crypto.createHash('md5'); m.update(password + key); var iv = m.digest('hex'); console.log(iv); var data = new Buffer(input, 'utf8').toString('binary'); var cipher = crypto.createCipheriv('aes-256-cbc', key, iv.slice(0,16)); var encrypted = cipher.update(data, 'binary') + cipher.final('binary'); var encoded = new Buffer(encrypted, 'binary').toString('base64'); callback(encoded); }; var decrypt =

I am having an issue generating the correct signature in NodeJS (using crypto.js) when the text I am trying to encrypt has accented characters (such as ä,ï,ë) generateSignature = function (str, secKey) { var hmac = crypto.createHmac('sha1', secKey); var sig = hmac.update(str).digest('hex'); return sig; }; This function will return the correct HMAC signature if 'str' contains no accented characters (chars such as ä,ï,ë). If there are accented chars present in the text, it will not return the correct HMAC. The accented characters are valid in UTF8 encoding so I dont know why crypto has a problem

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 apsillers 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.pbkdf2 , which requires a callback. If your previous code looked like var result = crypto.pbkdf2Sync

Problem I have node.js module that is using crypto.createHash to generate md5 hash. Recently I noticed that hash generated by crypto module is different in new versions: Code require('crypto').createHash('md5').update('¥').digest('hex') Node.js v0.10.0 Outputs: ab3af8566ddd20d7efc9b314abe90755 Node.js v6.1.0 Outputs: 07625e142e4ac5961de57472657a88c1 Question I was wondering what causes that in new version and how can I solve this?

I'm having weird issues with Node's crypto library. I wrote this simple AES testing script: var cipher = crypto.createCipher('aes-256-cbc','InmbuvP6Z8') var text = "123|123123123123123"; cipher.update(text,'utf8','hex') var crypted = cipher.final('hex') var decipher = crypto.createDecipher('aes-256-cbc','InmbuvP6Z8') decipher.update(crypted,'hex','utf8') var dec = decipher.final('utf8') When I do console.log(dec), it's null. For some reason if I set test to "123|123123", it works. So why does "123|123123" work but "123|123123123123123" doesn't? RandomEtc You need to store the return from

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) { // need to salt and hash this password I think to compare // how to I get the salt? } In whatever

I want to create a hash of I love cupcakes (signed with the key abcdeg ) How can I create that hash, using Node.js Crypto? Documentation for crypto: http://nodejs.org/api/crypto.html var crypto = require('crypto') , text = 'I love cupcakes' , key = 'abcdeg' , hash hash = crypto.createHmac('sha1', key).update(text).digest('hex') A few years ago it was said that update() and digest() were legacy methods and the new streaming API approach was introduced. Now the docs say that either method can be used. For example: var crypto = require('crypto'); var text = 'I love cupcakes'; var secret = 'abcdeg
