ECDH usage

[Rush]

I am a bit baffled how to use your ECDH functionality, I would expect the following to log the same results. Follow the comments

  var keys1 = sjcl.ecc.elGamal.generateKeys(256); // peer1 generates keys 
  var keys2 = sjcl.ecc.elGamal.generateKeys(256); // peer2 generates keys
  var kem1 = keys2.pub.kem(0); // peer1 generates kem from peer2's public
  var kem2 = keys1.pub.kem(0); // peer2 generates kem from peer1's public
  console.log(keys1.sec.unkem(kem2.tag)); // peer1 calculates shared key
  console.log(keys2.sec.unkem(kem1.tag)); // peer2 calculates shared key

Unfortunately the above does not arrive at the same result. What am I missing? Thanks for the help.

First: Do not add a 0 as the second parameter to kem. This is the paranoia. Zero means that you do not care at all whether the random generator is properly seeded or not.
Second: If you want Diffie-hellmann use the dh function of a secret key.
Code:

 var keys1 = sjcl.ecc.elGamal.generateKeys(256); // peer1 generates keys 
 var keys2 = sjcl.ecc.elGamal.generateKeys(256); // peer2 generates keys
console.log(keys1.sec.dh(keys2.pub))
console.log(keys2.sec.dh(keys1.pub))

Forgot to thank you for the answer. ;) Thanks!
