Class EncryptedPrivateKey

java.lang.Object

org.bitcoinj.crypto.EncryptedPrivateKey

public class EncryptedPrivateKey
extends Object

An EncryptedPrivateKey contains the information produced after encrypting the private key bytes of an ECKey.

It contains two member variables - initialisationVector and encryptedPrivateBytes. The initialisationVector is a randomly chosen list of bytes that were used to initialise the AES block cipher when the private key bytes were encrypted. You need these for decryption. The encryptedPrivateBytes are the result of AES encrypting the private keys using an AES key that is derived from a user entered password. You need the password to recreate the AES key in order to decrypt these bytes.
