Looking for help to port below C# code into Node.js using crypto or equivalent module.
private string password="FlU4c8yQKLkYuFwsgyU4LFeIf7m3Qwy+poMBdULEMqw=";
private byte[] salt = Encoding.ASCII.GetBytes("##oEDA102ExChAnGe99#$#");
Aes encryptor = Aes.Create();
Rfc2898DeriveBytes pdb = new Rfc2898DeriveBytes(password, salt);
string pdbStr = Convert.ToBase64String(pdb.GetBytes(32));
Console.WriteLine(pdbStr);
encryptor.Key = pdb.GetBytes(32);
encryptor.IV = pdb.GetBytes(16);
Tried porting into javascript as below, but the resulted value are not the same.
var password = "FlU4c8yQKLkYuFwsgyU4LFeIf7m3Qwy+poMBdULEMqw=";
var salt = "##oEDA102ExChAnGe99#$#";
var pdbBytes = crypto.pbkdf2Sync(Buffer.from(password, 'base64'), new Buffer(salt, 'base64'), 1000, 32);
var pdbStr = new Buffer(pdbBytes).toString('base64')
console.log("pdbStr", pdbStr);
Console output: C# - GZlqgdLbMQ753dTmx1nlJ6HgdabTjW1CeCSoIYkLM4E= JS - tuDsZJEEwxyXP7RvuYVxGmDy20AvMJAqkLoXX78sEU8=
Any help is much appreciated. Thanks.
回答1:
these codes parts are generating same the result.
but i did not get 'GZlqgdLbMQ753dTmx1nlJ6HgdabTjW1CeCSoIYkLM4E=' result from c#.
c#
byte[] password= Convert.FromBase64String("FlU4c8yQKLkYuFwsgyU4LFeIf7m3Qwy+poMBdULEMqw=");
byte[] salt = Encoding.ASCII.GetBytes("##oEDA102ExChAnGe99#$#");
Rfc2898DeriveBytes pdb = new Rfc2898DeriveBytes(password,salt,1000);
string pdbStr =Convert.ToBase64String(pdb.GetBytes(32));
Console.WriteLine(pdbStr);
//outpu : RMqDMSV6d8uT2NicGM212r3KMFt7ZsOI2q8+0Rr0WZQ=
JS
var crypto = require("crypto");
var password = "FlU4c8yQKLkYuFwsgyU4LFeIf7m3Qwy+poMBdULEMqw=";
var salt = "##oEDA102ExChAnGe99#$#";
crypto.DEFAULT_ENCODING = 'base64';
var pdbBytes = crypto.pbkdf2Sync(new Buffer(password,'base64'), salt, 1000, 32,'sha1');
var pdbStr = new Buffer(pdbBytes).toString()
console.log("pdbStr", pdbStr);
//outpu : RMqDMSV6d8uT2NicGM212r3KMFt7ZsOI2q8+0Rr0WZQ=
