<p>You can enter any version of a valid Bitcoin extended public/private key and convert it to another version of the same extended key. (For example, exporting an xpub/ypub/zpub from Ledger Live to use in some other wallet or tool.)</p>
<p>
For more info see <a href="https://github.com/satoshilabs/slips/blob/master/slip-0132.md" target="_blank">SLIP-0132</a>.

<p><b>The online version of this tool should only ever be used for working with extended public keys (xpub, etc) or for testing/education purposes...</b>
<br>
You should normally never need to convert or handle xprv keys except in VERY SPECIFIC recovery situations... Working with extended private keys (xprv/yprv/zprv, etc) should only ever be done in an offline (all networking disconnected), amnesic environment like TAILS Linux... <a href="https://github.com/3rdIteration/btc-extended-key-converter/archive/master.zip">Click here to download a zip file containing this tool to run offline</a> </p>
