org.bitcoinj.core.DumpedPrivateKey

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.lang.Comparable<PrefixedChecksummedBytes>

public class DumpedPrivateKey
extends PrefixedChecksummedBytes

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,
                                          java.lang.String base58)
                                   throws AddressFormatException,
                                          AddressFormatException.WrongNetwork

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

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

toBase58

public java.lang.String toBase58()

Returns the base58-encoded textual form, including version and checksum bytes.

Returns:

textual form

getKey

public ECKey getKey()

Returns an ECKey created from this encoded private key.

isPubKeyCompressed

public boolean isPubKeyCompressed()

Returns true if the public key corresponding to this private key is compressed.

toString

public java.lang.String toString()

Overrides:
