# Usage
# About This Package
`@harmony-js/account` is dealing with account related features.
Developers can use this packages to:
* create `Account` instance
* create `Wallet` instance
* sign `Transaction`
* convert address format
* manage `privateKey` or `mnemonic phrases` and do the `encrypt` and `decrypt` job
There are 2 main classes in this package, `Account` and `Wallet`.
The `Account` class is basic instance that contains most features mentioned above.
The `Wallet` class is class that stores all `Account` instance, you can do CRUD on it.
# Usage of Account
## Dependencies
* "@harmony-js/network",
* "@harmony-js/staking",
* "@harmony-js/transaction",
* "@harmony-js/utils"
## Examples
### create a random account
```typescript
// import the Account class
import {Account} from '@harmony-js/account'
// Messenger is optional, by default, we have a defaultMessenger
// If you like to change, you will import related package here.
import { HttpProvider, Messenger } from '@harmony-js/network';
import { ChainType, ChainID } from '@harmony-js/utils';
// create a custom messenger
const customMessenger = new Messenger(
new HttpProvider('http://localhost:9500'),
ChainType.Harmony, // if you are connected to Harmony's blockchain
ChainID.HmyLocal, // check if the chainId is correct
)
// to create an Account with random privateKey
// and you can setMessenger later
const randomAccount = new Account()
randomAccount.setMessenger(customMessenger)
// or you can set messenger on `new`
const randomAccountWithCustomMessenger = new Account(undefined, customMessenger)
// you can display the account
console.log({randomAccount,randomAccountWithCustomMessenger})
// or you can use static method to create an Account
const staticCreatedAccount = Account.new()
// but you have to set messenger manually after
staticCreatedAccount.setMessenger(customMessenger)
console.log({staticCreatedAccount})
```
### import an existing privateKey to create Account
```typescript
// import the Account class
import {Account} from '@harmony-js/account'
// NOTED: Key with or without `0x` are accepted, makes no different
// NOTED: DO NOT import `mnemonic phrase` using `Account` class, use `Wallet` instead
const myPrivateKey = '0xe19d05c5452598e24caad4a0d85a49146f7be089515c905ae6a19e8a578a6930'
const myAccountWithMyPrivateKey = new Account(myPrivateKey)
// you can also import privateKey use static method
const myAccountWithMyPrivateKeyUsingStatic = Account.add(myPrivateKey)
console.log({ myAccountWithMyPrivateKey, myAccountWithMyPrivateKeyUsingStatic })
```
### Encrypt/Export keyStore file, Decrypt/Import keyStore file
```typescript
// import the Account class
import {Account} from '@harmony-js/account'
// suppose we have an account
const myPrivateKey = '0xe19d05c5452598e24caad4a0d85a49146f7be089515c905ae6a19e8a578a6930'
const myAccountWithMyPrivateKey = new Account(myPrivateKey)
// suppose we have a password, and we want to encrypt the account above
const myStrongPassword = '123'
async function encryptAndDecrypt(password) {
// we get the privateKey before encrypted as comparison
const unencryptedPrivateKey = myAccountWithMyPrivateKey.privateKey
// export the account to keyStore string, which will make the privateKey encrpyted
const keyStoreFile = await myAccountWithMyPrivateKey.toFile(password)
// exported keyStoreFile
console.log({ keyStoreFile })
// see if the account is encrypted
console.log(`Is this account encrypted? \n ${myAccountWithMyPrivateKey.encrypted}`)
// keystore file should be equal to encrypted privateKey
console.log(
`Is privateKey equal to keyStore string? \n ${keyStoreFile ===
myAccountWithMyPrivateKey.privateKey}`,
)
}
encryptAndDecrypt(myStrongPassword)
// suppose we have keyStorefile, in this example, we just use same password and keystore string encrypted above
const someKeyStoreFile =
'{"version":3,"id":"62326332-3139-4839-b534-656134623066","address":"1fe3da351d9fc0c4f02de5412ad7def8aee956c5","Crypto":{"ciphertext":"b86ab81682c9f5a35738ad9bd38cd9b46c1b852ef33f16dd83068f79e20d5531","cipherparams":{"iv":"44efb5a514f34968e92cafad80566487"},"cipher":"aes-128-ctr","kdf":"scrypt","kdfparams":{"salt":"d70ae1f311601562113f98c8ebe382f52a332dca1588886e5ea91e2f8a647134","n":8192,"r":8,"p":1,"dklen":32},"mac":"7b63e4e31a75a22b7091291bb58302655b738539ef3e30b30a7a7f170f6163ef"}}'
async function importKeyStoreFileAndDecrypt(keyStoreFile, password) {
// import keyStore string and provide the password, remember to make a new Account first
const importedAccount = await Account.new().fromFile(keyStoreFile, password)
// the account should decypted which `Account.encrypted` is false
console.log(`Is this account encrypted? \n ${importedAccount.encrypted}`)
// see if the privatekey is equal to unencrypted one?
console.log(
`Is the account recovered from keystore? \n ${importedAccount.privateKey === myPrivateKey}`,
)
}
importKeyStoreFileAndDecrypt(someKeyStoreFile, myStrongPassword)
```
### Address format getter
```typescript
// import the Account class
import {Account} from '@harmony-js/account'
// suppose we have an account
const myPrivateKey = '0xe19d05c5452598e24caad4a0d85a49146f7be089515c905ae6a19e8a578a6930'
const myAccountWithMyPrivateKey = new Account(myPrivateKey)
// Account.address is bytes20/base16 address
console.log(myAccountWithMyPrivateKey.address)
// Account.bech32Address is bech32 format address, in Harmony, it's `one1` prefixed
console.log(myAccountWithMyPrivateKey.bech32Address)
// Account.bech32TestNetAddress is bech32 format address, in Harmony, it's `tone1` prefixed, used in testnet
console.log(myAccountWithMyPrivateKey.bech32TestNetAddress)
// Account.checksumAddress is checksumed address from base16
console.log(myAccountWithMyPrivateKey.checksumAddress)
```
