I have a server which encrypts the some data using 

var key = new Buffer('Kay8u5Dev5al7', 'utf-8');

var encrypt = function(key, data) {
    var cipher = crypto.createCipher('aes256', key);
    var crypted = cipher.update(data, 'utf-8', 'hex');
    crypted += cipher.final('hex');
    return crypted;
}

Now I want to decrypt the data back using a java client.

Though I referred some examples to decrypt in java I could'nt get the data back. I am using JCE security jars at the client side.

  • Note that crypto.createCipher uses a password and not a key. You would need to replicate EVP_bytesToKey in Java. Commented Oct 28, 2015 at 14:08
  • Late but @ArtjomB.: you only need EVP_BytesToKey for the case no salt, MD5, and one iteration (!!), which is relatively easy, plus there are several Qs with the needed code if you look. Commented May 12, 2018 at 10:24
  • @dave_thompson_085 Good thing, I've done that already with this answer of mine. Commented May 12, 2018 at 11:27
