<div class="notes">
Your Bitcoin Private Key is a unique secret number that only you know. It can be be encoded in a number of different formats.
Below we show the Bitcoin Address and Public Key that corresponds to your Private Key as well as your Private Key in the most popular encoding formats (WIF, HEX, B64, MINI).
Bitcoin v0.6+ stores public keys in compressed format. The client now also supports import and export of private keys with importprivkey/dumpprivkey. The format of the exported
private key is determined by whether the address was generated in an old or new wallet.
