DumpedPrivateKey (bitcoinj-core 0.16.2 API)

java.lang.Object
- org.bitcoinj.core.PrefixedChecksummedBytes
- - org.bitcoinj.core.DumpedPrivateKey

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable
```
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.

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:

```
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()
