Hi,
As usual, the thing to do in these cases is to get a very small example
working and then extend it to match your full / final use case.
I don't know the python crypto stuff and it's not obvious from the snippet
you posted which AES/ECB cipher you are using. This could be the source
of your problems.
See :
crypto.getCiphers()
Returns an array with the names of the supported ciphers.

Anyway, here is a short example using aes-128-ecb and your key :
---- Encode :
var cipherType = "aes-128-ecb";
var cipherKey = "9kL8yb/3Tu2czOr5qfiGPgJmx25s+T15";
var ecb = new Buffer("hello there");
var cipher = crypto.createCipher(cipherType, cipherKey);var t = [];
cipher.setAutoPadding(true);t.push(cipher.update(ecb, "ascii", "hex"))
t.push(cipher.final("hex"));
console.log(t.join(''));
-----Decode :
var fs = require('fs'),
crypto = require('crypto');
var cipherType = "aes-128-ecb";
var cipherKey = "9kL8yb/3Tu2czOr5qfiGPgJmx25s+T15";
var ecb = fs.readFileSync("./encrypted.txt", "ascii").trim();
var decipher = crypto.createDecipher(cipherType, cipherKey);
var t = [];
t.push(decipher.update(ecb, "hex", "ascii"));
t.push(decipher.final("ascii"));
console.log(t.join(''));
