### personal_importRawKey
|
|
|
|
Imports the given unencrypted private key (hex string) into the key store,
|
|
encrypting it with the passphrase.
|
|
|
|
Returns the address of the new account.
|
|
|
|
| Client | Method invocation |
|
|
| :--------| ----------------------------------------------------------------- |
|
|
| Console | `personal.importRawKey(keydata, passphrase)` |
|
|
| RPC | `{"method": "personal_importRawKey", "params": [string, string]}` |
|
|
|
|
### personal_listAccounts
|
|
|
|
Returns all the Ethereum account addresses of all keys
|
|
in the key store.
|
|
|
|
| Client | Method invocation |
|
|
| :--------| --------------------------------------------------- |
|
|
| Console | `personal.listAccounts` |
|
|
| RPC | `{"method": "personal_listAccounts", "params": []}` |
|
|

|
|
```
|
|
|
|
### personal_lockAccount
|
|
|
|
Removes the private key with given address from memory.
|
|
The account can no longer be used to send transactions.
|
|
|
|
| Client | Method invocation |
|
|
| :--------| -------------------------------------------------------- |
|
|
| Console | `personal.lockAccount(address)` |
|
|
| RPC | `{"method": "personal_lockAccount", "params": [string]}` |
|
|
|
|
### personal_newAccount
|
|
|
|
Generates a new private key and stores it in the key store directory.
|
|
The key file is encrypted with the given passphrase.
|
|
Returns the address of the new account.
|
|
|
|
At the geth console, `newAccount` will prompt for a passphrase when
|
|
it is not supplied as the argument.
|
|
|
|
| Client | Method invocation |
|
|
| :--------| --------------------------------------------------- |
|
|
| Console | `personal.newAccount()` |
|
|
| RPC | `{"method": "personal_newAccount", "params": [string]}` |
|
|
|
|
#### Example
|
|
|
|
``` javascript
|
|
> personal.newAccount()
|
|
Passphrase:
|
|
Repeat passphrase:
|
|
"0x5e97870f263700f46aa00d967821199b9bc5a120"
|
|
```
|
|
|
|
The passphrase can also be supplied as a string.
|
|
|
|
``` javascript
|
|
> personal.newAccount("h4ck3r")
|
|
"0x3d80b31a78c30fc628f20b2c89d7ddbf6e53cedc"
|
|
```
|
|
|
|
### personal_unlockAccount
|
|
|
|
Decrypts the key with the given address from the key store.
|
|
|
|
Both passphrase and unlock duration are optional when using the JavaScript console.
|
|
If the passphrase is not supplied as an argument, the console will prompt for
|
|
the passphrase interactively.
|
|
|
|
The unencrypted key will be held in memory until the unlock duration expires.
|
|
If the unlock duration defaults to 300 seconds. An explicit duration
|
|
of zero seconds unlocks the key until geth exits.
|
|
|
|
The account can be used with `eth_sign` and `eth_sendTransaction` while it is unlocked.
|
|
|
|
| Client | Method invocation |
|
|
| :--------| -------------------------------------------------------------------------- |
|
|
| Console | `personal.unlockAccount(address, passphrase, duration)` |
|
|
| RPC | `{"method": "personal_unlockAccount", "params": [string, string, number]}` |
|
|
|
|
#### Examples
|
|
|
|
``` javascript
|
|
> personal.unlockAccount("0x5e97870f263700f46aa00d967821199b9bc5a120")
|
|
Unlock account 0x5e97870f263700f46aa00d967821199b9bc5a120
|
|
Passphrase:
|
|
true
|
|
```
|
|
|
|
Supplying the passphrase and unlock duration as arguments:
|
|
|
|
``` javascript
|
|
> personal.unlockAccount("0x5e97870f263700f46aa00d967821199b9bc5a120", "foo", 30)
|
|
true
|
|
```
|
|
|
|
If you want to type in the passphrase and stil override the default unlock duration,
|
|
pass `null` as the passphrase.
|
|
|
|
```
|
|
> personal.unlockAccount("0x5e97870f263700f46aa00d967821199b9bc5a120", null, 30)
|
|
Unlock account 0x5e97870f263700f46aa00d967821199b9bc5a120
|
|
Passphrase:
|
|
true
|
|
```
|
|
|
|
### personal_sendTransaction
|
|
|
|
Validate the given passphrase and submit transaction.
|
|
|
|
The transaction is the same argument as for `eth_sendTransaction` and contains the `from` address. If the passphrase can be used to decrypt the private key belogging to `tx.from` the transaction is verified, signed and send onto the network. The account is not unlocked globally in the node and cannot be used in other RPC calls.
|
|
|
|
| Client | Method invocation |
|
|
| :--------| -----------------------------------------------------------------|
|
|
| Console | `personal.sendTransaction(tx, passphrase)` |
|
|
| RPC | `{"method": "personal_sendTransaction", "params": [tx, string]}` |
|
|
|
|
*Note, prior to Geth 1.5, please use `personal_signAndSendTransaction` as that was the
|
|
original introductory name and only later renamed to the current final version.*
|
|
|
|
#### Examples
|
|
|
|
``` javascript
|
|
> var tx = {from: "0x391694e7e0b0cce554cb130d723a9d27458f9298", to: "0xafa3f8684e54059998bc3a7b0d2b0da075154d66", value: web3.toWei(1.23, "ether")}
|
|
undefined
|
|
> personal.sendTransaction(tx, "passphrase")
|
|
0x8474441674cdd47b35b875fd1a530b800b51a5264b9975fb21129eeb8c18582f
|
|
```
|
|
|
|
### personal_sign
|
|
|
|
The sign method calculates an Ethereum specific signature with:
|
|
`sign(keccack256("\x19Ethereum Signed Message:\n" + len(message) + message)))`.
|
|
|
|
By adding a prefix to the message makes the calculated signature recognisable as an Ethereum specific signature. This prevents misuse where a malicious DApp can sign arbitrary data (e.g. transaction) and use the signature to impersonate the victim.
|
|
|
|
See ecRecover to verify the signature.
|
|
|
|
| Client | Method invocation |
|
|
|:--------|-------------------------------------------------------|
|
|
| Console | `personal.sign(message, account, [password])` |
|
|
| RPC | `{"method": "personal_sign", "params": [message, account, password]}` |
|
|
|
|
|
|
#### Examples
|
|
|
|
``` javascript
|
|
> personal.sign("0xdeadbeaf", "0x9b2055d370f73ec7d8a03e965129118dc8f5bf83", "")
|
|
"0xa3f20717a250c2b0b729b7e5becbff67fdaef7e0699da4de7ca5895b02a170a12d887fd3b17bfdce3481f10bea41f45ba9f709d39ce8325427b57afcfc994cee1b"
|
|
```
|
|
|
|
### personal_ecRecover
|
|
|
|
`ecRecover` returns the address associated with the private key that was used to calculate the signature in `personal_sign`.
|
|
|
|
| Client | Method invocation |
|
|
|:--------|-------------------------------------------------------|
|
|
| Console | `personal.ecRecover(message, signature)` |
|
|
| RPC | `{"method": "personal_ecRecover", "params": [message, signature]}` |
|
|
|
|
|
|
#### Examples
|
|
|
|
``` javascript
|
|
> personal.sign("0xdeadbeaf", "0x9b2055d370f73ec7d8a03e965129118dc8f5bf83", "")
|
|
"0xa3f20717a250c2b0b729b7e5becbff67fdaef7e0699da4de7ca5895b02a170a12d887fd3b17bfdce3481f10bea41f45ba9f709d39ce8325427b57afcfc994cee1b"
