Packages that use org.bitcoinj.crypto

Package	Description
org.bitcoinj.core	The core package contains classes for network messages like Block and Transaction, peer connectivity via PeerGroup, and block chain management.
org.bitcoinj.crypto	The crypto package contains classes that work with key derivation algorithms like scrypt (passwords to AES keys), BIP 32 hierarchies (chains of keys from a root seed), X.509 utilities for the payment protocol and other general cryptography tasks.
org.bitcoinj.protocols.channels	Micropayment channels allow for rapid tiny payments to be made to a third party once a channel has been set up, using some of the advanced features of the Bitcoin protocol.
org.bitcoinj.protocols.payments	The BIP70 payment protocol wraps Bitcoin transactions and adds various useful features like memos, refund addresses and authentication.
org.bitcoinj.script	Classes for working with and executing Bitcoin script programs, as embedded in inputs and outputs.
org.bitcoinj.signers	Transaction signers know how to calculate signatures over transactions in different contexts, for example, using local private keys or fetching them from remote servers.
org.bitcoinj.wallet	Classes that support the Wallet, which knows how to find and save transactions relevant to a set of keys or scripts, calculate balances, and spend money: the wallet has many features and can be extended in various ways, please refer to the website for documentation on how to use it.

Classes in org.bitcoinj.crypto used by org.bitcoinj.core

Class and Description
EncryptableItem Provides a uniform way to access something that can be optionally encrypted with a KeyCrypter, yielding an EncryptedData, and which can have a creation time associated with it.
EncryptedData An instance of EncryptedData is a holder for an initialization vector and encrypted bytes.
KeyCrypter A KeyCrypter can be used to encrypt and decrypt a message.
KeyCrypterException Exception to provide the following:
LazyECPoint A wrapper around ECPoint that delays decoding of the point for as long as possible.
TransactionSignature A TransactionSignature wraps an ECKey.ECDSASignature and adds methods for handling the additional SIGHASH mode byte that is used.
