<p>I'm looking for a script/pseudocode/utility (preferably, code in javascript/c++ or a secure, verified and open-source rpc client) that can convert a given xpriv to xpub.</p>

<p>Only one I've found (but not tried yet) is this one  :
<a href="https://github.com/sarchar/brainwallet.github.com/tree/bip32" rel="nofollow noreferrer">https://github.com/sarchar/brainwallet.github.com/tree/bip32</a></p>

<p>or I know electrum wallet client can do it. I would prefer to read through the code of a standalone script though and/or create my own script</p>
