Hashing a password using SHA256 and .NET/Node.js
.net, hash, javascript, node.js, sha2
Solution
Edit: You are using UTF-16 in C#, you must use same encoding in both languages:
Node.js:
var crypto = require("crypto");
var sha256 = crypto.createHash("sha256");
sha256.update("ThisPassword", "utf8");//utf8 here
var result = sha256.digest("base64");
console.log(result); //d7I986+YD1zS6Wz2XAcDv2K8yw3xIVUp7u/OZiDzhSY=
C#:
SHA256 sha256 = SHA256Managed.Create(); //utf8 here as well
byte[] bytes = sha256.ComputeHash(Encoding.UTF8.GetBytes("ThisPassword"));
string result = Convert.ToBase64String(bytes);
Console.WriteLine(result); //d7I986+YD1zS6Wz2XAcDv2K8yw3xIVUp7u/OZiDzhSY=
Problem
Im Storing SHA256 hashes of user passwords in my database generated by .NET and I need to be able to check them with Node.js. The only problem is that .NET and Node.js create different hashes for the same password. ``` Password: ThisPassword ``` .NET: ``` var ue = new UnicodeEncoding(); var byteSourceText = ue.GetBytes("ThisPassword"); var byteHash = new System.Security.Cryptography.SHA256Managed().ComputeHash(byteSourceText); return Convert.ToBase64String(byteHash); //Tlwxyd7HIQhXkN6DrWJtmB9Ag2fz84P/QgMtbi9XS6Q= ``` Node.js (Using Crypto): ``` var crypto = require('crypto'); return crypto.createHash('sha256').update('ThisPassword').digest('base64') //d7I986+YD1zS6Wz2XAcDv2K8yw3xIVUp7u/OZiDzhSY= ``` I found this, but was unable to figure out how to implement his solution.
