If you are looking for a challenge, this Javascript code will do it (requires Node.js):

Code:
 Crypto = require('crypto');
  ecdh = Crypto.createECDH('secp256k1');
  ecdh.setPrivateKey(privKey);
  publicKey = ecdh.getPublicKey(null, 'compressed');

Lol thank you. Do you know python?

I am hoping someone can provide mean script preferably python that converts private key in binary and/or hex and converts to public key. Preferably just the X coordinate. Y coordinate is fine also or compressed/uncompressed. Don't need the address generated I can do that myself just wanted a stand alone script. Thanks
