考虑到来自 http://www.thoughtcrime.org/blog/the-cryptographic-doom-principle/ (简而言之:首先加密，然后验证。之后先验证，然后解密) 我在node.js中实现了以下解决方案:

function encrypt(text,password){
  var cipher = crypto.createCipher(algorithm,password)
  var crypted = cipher.update(text,'utf8','hex')
  crypted += cipher.final('hex');
  return crypted;
}

function decrypt(text,password){
  var decipher = crypto.createDecipher(algorithm,password)
  var dec = decipher.update(text,'hex','utf8')
  dec += decipher.final('utf8');
  return dec;
}

function hashText(text){
    var hash = crypto.createHash('md5').update(text).digest("hex");
    //console.log(hash); 
    return hash;
}

function encryptThenAuthenticate(plainText,pw)
{
    var encryptedText = encrypt(plainText,pw);
    var hash = hashText(encryptedText);
    return encryptedText+"$"+hash;
}
function VerifyThenDecrypt(encryptedAndAuthenticatedText,pw)
{
    var encryptedAndHashArray = encryptedAndAuthenticatedText.split("$");
    var encrypted = encryptedAndHashArray[0];
    var hash = encryptedAndHashArray[1];
    var hash2Compare = hashText(encrypted);
    if (hash === hash2Compare)
    {
        return decrypt(encrypted,pw); 
    }
}

它可以用以下方法进行测试:

var doom = encryptThenAuthenticate("The encrypted text",user.cryptoPassword);
console.log(VerifyThenDecrypt(doom,user.cryptoPassword));

希望这对你有所帮助:-)

我不得不把我的2美分扔在希望这能帮助某人。

对于那些使用CommonJS的人

const crypto = require('crypto');
const secret = 'I love writing code, fixing things and building helpful tools';
const hash = crypto.createHmac('sha256', secret).digest('hex');

console.log('Hash successfully generated: ', hash);

适用于使用ES模块的用户

const { createHmac } = await import('crypto');
const secret = 'I love writing code, fixing things and building helpful tools';
const hash = createHmac('sha256', secret).digest('hex');

console.log('Hash successfully generated: ', hash);

超级简单! 快乐编码:)

使用PBKDF2在NodeJs中进行密码哈希

const pbkdf2 = require("pbkdf2");
const crypto = require("crypto");

// UserSchema
//...

// Method to create pbkdf2 hash from plain text
UserSchema.methods.createHash = async function (plainTextPassword) {

  // Generate a salt and then create hash
  const salt = crypto.randomBytes(16).toString("hex");
  const hashedPassword = pbkdf2
    .pbkdf2Sync(plainTextPassword, salt, 10, 32, "sha512")
    .toString("hex");

  // Saving both the dynamic salt and hash in the Database
  return [salt, hashedPassword].join("#");
};

// Validating the password with pbkdf2 hash
UserSchema.methods.validatePassword = async function (candidatePassword) {
  const hashedPassword = this.password_hash.split("#")[1];
  const salt = this.password_hash.split("#")[0];

  const hash = pbkdf2
    .pbkdf2Sync(candidatePassword, salt, 10, 32, "sha512")
    .toString("hex");

  if (hash === hashedPassword) {
    return true;
  }
  return false;
};

module.exports.User = mongoose.model("User", UserSchema);

使用Argon2在NodeJs中进行密码哈希

const argon2 = require("argon2");

// UserSchema
...

// Method to generate Hash from plain text  using argon2
UserSchema.methods.createHash = async function (plainTextPassword) {
    // return password hash
    return await argon2.hash(plainTextPassword);
};

// Method to validate the entered password using argon2
UserSchema.methods.validatePassword = async function (candidatePassword) {
  return await argon2.verify(this.password_hash, candidatePassword)
};

module.exports.User = mongoose.model("User", UserSchema);

如果你只是想md5哈希一个简单的字符串，我发现这对我有用。

var crypto = require('crypto');
var name = 'braitsch';
var hash = crypto.createHash('md5').update(name).digest('hex');
console.log(hash); // 9b74c9897bac770ffc029102a200c5de
