Class DumpedPrivateKey

java.lang.Object

org.bitcoinj.core.VersionedChecksummedBytes

org.bitcoinj.core.DumpedPrivateKey

All Implemented Interfaces:

Serializable, Cloneable, Comparable<VersionedChecksummedBytes>

public class DumpedPrivateKey
extends VersionedChecksummedBytes

Parses and generates private keys in the form used by the Bitcoin "dumpprivkey" command. This is the private key bytes with a header byte and 4 checksum bytes at the end. If there are 33 private key bytes instead of 32, then the last byte is a discriminator value for the compressed pubkey.

Method Detail

fromBase58

public static DumpedPrivateKey fromBase58(@Nullable
                                          NetworkParameters params,
                                          String base58)
                                   throws AddressFormatException

Construct a private key from its Base58 representation.

Parameters:

params - The expected NetworkParameters or null if you don't want validation.

base58 - The textual form of the private key.

Throws:

AddressFormatException - if the given base58 doesn't parse or the checksum is invalid

WrongNetworkException - if the given private key is valid but for a different chain (eg testnet vs mainnet)

getKey

public ECKey getKey()

Returns an ECKey created from this encoded private key.

equals
