org.bitcoinj.crypto.KeyCrypter

Packages that use KeyCrypter

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.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.
