passwordfile as argument containing the wallet password in plaintext.

Description: `
|
|
|
|
Manage accounts lets you create new accounts, list all existing accounts,
|
|
import a private key into a new account.
|
|
|
|
' help' shows a list of subcommands or help for one subcommand.
|
|
|
|
It supports interactive mode, when you are prompted for password as well as
|
|
non-interactive mode where passwords are supplied via a given password file.
|
|
Non-interactive mode is only meant for scripted use on test networks or known
|
|
safe environments.
|
|
|
|
Make sure you remember the password you gave when creating a new account (with
|
|
either new or import). Without it you are not able to unlock your account.
|
|
|
|
Note that exporting your key in unencrypted format is NOT supported.
|
|
|
|
Keys are stored under <DATADIR>/keystore.
|
|
It is safe to transfer the entire directory or the individual keys therein
|
|
between ethereum nodes by simply copying.
|
|
Make sure you backup your keys regularly.
|
|
|
|
In order to use your account to send transactions, you need to unlock them using
|
|
the '--unlock' option. The argument is a space separated list of addresses or
|
|
indexes. If used non-interactively with a passwordfile, the file should contain
|
|
the respective passwords one per line. If you unlock n accounts and the password
|
|
file contains less than n entries, then the last password is meant to apply to
|
|
all remaining accounts.
|
|
|
|
And finally. DO NOT FORGET YOUR PASSWORD.

Creates a new account. Prints the address.

The account is saved in encrypted format, you are prompted for a passphrase.
|
|
|
|
You must remember this passphrase to unlock your account in the future.
|

For non-interactive use the passphrase can be specified with the --password flag:
|
|
|
|
ethereum --password <passwordfile> account new
|
|
|

Note, this is meant to be used for testing only, it is a bad idea to save your

ethereum account update <address>
|
|
|
|
Update an existing account.
|
|
|
|
The account is saved in the newest version in encrypted format, you are prompted
|
|
for a passphrase to unlock the account and another to save the updated file.
|
|
|
|
This same command can therefore be used to migrate an account of a deprecated
|
|
format to the newest format or change the password for an account.
|
|
|
|
For non-interactive use the passphrase can be specified with the --password flag:
|
|
|
|
ethereum --password <passwordfile> account update <address>
|
|
|
|
Since only one password can be given, only format update can be performed,

changing your password is only possible interactively.

Description: `
|
|
|
|
ethereum account import <keyfile>
|
|
|
|
Imports an unencrypted private key from <keyfile> and creates a new account.
|
|
Prints the address.
|
|
|
|
The keyfile is assumed to contain an unencrypted private key in hexadecimal format.
|
|
|
|
The account is saved in encrypted format, you are prompted for a passphrase.
|
|
|
|
You must remember this passphrase to unlock your account in the future.
|
|
|
|
For non-interactive use the passphrase can be specified with the -password flag:
|
|
|
|
ethereum --password <passwordfile> account import <keyfile>
|
|
|
|
Note:
|
|
As you can directly copy your encrypted accounts to another ethereum instance,
|
|
this import mechanism is not needed when you transfer an account between
|
|
nodes.
