Interface Summary

KeyCrypter

A KeyCrypter can be used to encrypt and decrypt a message.

Class Summary

ChildNumber	This is just a wrapper for the i (child number) as per BIP 32 with a boolean getter for the first bit and a getter for the actual 0-based child number.
DeterministicHierarchy	A DeterministicHierarchy calculates and keeps a whole tree (hierarchy) of keys originating from a single root key.
DeterministicKey	A deterministic key is a node in a DeterministicHierarchy.
EncryptedPrivateKey	An EncryptedPrivateKey contains the information produced after encrypting the private key bytes of an ECKey.
HDKeyDerivation	Implementation of the (public derivation version) deterministic wallet child key generation algorithm.
HDUtils	Static utilities used in BIP 32 Hierarchical Deterministic Wallets (HDW).
KeyCrypterScrypt	This class encrypts and decrypts byte arrays and strings using scrypt as the key derivation function and AES for the encryption.
MnemonicCode	A MnemonicCode object may be used to convert between binary seed values and lists of words per the BIP 39 specification
PBKDF2SHA512	This is a clean-room implementation of PBKDF2 using RFC 2898 as a reference.
TransactionSignature	A TransactionSignature wraps an ECKey.ECDSASignature and adds methods for handling the additional SIGHASH mode byte that is used.

Exception Summary

HDDerivationException
KeyCrypterException	Exception to provide the following to EncrypterDecrypterOpenSSL:
MnemonicException	Exceptions thrown by the MnemonicCode module.
MnemonicException.MnemonicChecksumException	Thrown when a list of MnemonicCode words fails the checksum check.
MnemonicException.MnemonicLengthException	Thrown when an argument to MnemonicCode is the wrong length.
