Method Detail

fromBase58

public static BIP38PrivateKey fromBase58(Network network,
                                         java.lang.String base58)
                                  throws AddressFormatException

Construct a password-protected private key from its Base58 representation.

Parameters:

network - The network 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
