public static BIP38PrivateKey fromBase58(NetworkParameters params,
                                         java.lang.String base58)
                                  throws AddressFormatException
```
    Construct a password-protected private key from its Base58 representation.
    
    Parameters:
    
    params - The network parameters of the chain that the key is for.
    
    base58 - The textual form of the password-protected private key.
    
    Throws:
    
    AddressFormatException - if the given base58 doesn't parse or the checksum is invalid
  - toBase58
```
public java.lang.String toBase58()
```
    Returns the base58-encoded textual form, including version and checksum bytes.
    
    Returns:
