Method Detail

fromBase58

public static BIP38PrivateKey fromBase58(NetworkParameters params,
                                         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

decrypt

public ECKey decrypt(String passphrase)
              throws BIP38PrivateKey.BadPassphraseException

Throws:

BIP38PrivateKey.BadPassphraseException

equals

public boolean equals(Object o)

Overrides:
