Packages that use Sha256Hash

Package	Description
org.bitcoinj.core	The core package contains classes for network messages like Block and Transaction, peer connectivity via PeerGroup, block chain management and the Wallet class.
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.jni
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.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.store	Block stores persist blockchain data downloaded from remote peers.
org.bitcoinj.testing	Various utilities for writing unit tests: also useful for testing your own code and apps that build on top of bitcoinj.
