The Klaytn console is an interactive shell for the JavaScript runtime environment
which exposes a node admin interface as well as the Ðapp JavaScript API.
See https://github.com/ethereum/go-ethereum/wiki/JavaScript-Console.

var (
	AccountCommand = cli.Command{
		Name:     "account",
		Usage:    "Manage accounts",
		Category: "ACCOUNT COMMANDS",
		Description: `

Manage accounts, list all existing accounts, import a private key into a new
account, create a new account or update an existing account.

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 klay nodes by simply copying.

Make sure you backup your keys regularly.`,
		Subcommands: []cli.Command{
			{
				Name:   "list",
				Usage:  "Print summary of existing accounts",

					utils.NoPartitionedDBFlag,
					utils.NumStateTriePartitionsFlag,

					utils.DataDirFlag,
					utils.KeyStoreDirFlag,
					utils.PasswordFileFlag,
					utils.LightKDFFlag,
				},
				Description: `
    klay account new

Creates a new account and 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:

Note, this is meant to be used for testing only, it is a bad idea to save your
password to file or expose in any other way.
`,

			{
				Name:      "update",
				Usage:     "Update an existing account",

					utils.NumStateTriePartitionsFlag,
					utils.LevelDBCompressionTypeFlag,
					utils.DataDirFlag,
					utils.KeyStoreDirFlag,
					utils.LightKDFFlag,
				},
				Description: `
    klay 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:

    klay account update [options] <address>

Since only one password can be given, only format update can be performed,
changing your password is only possible interactively.
`,
			},
			{
				Name:   "import",
				Usage:  "Import a private key into a new account",
				Action: utils.MigrateFlags(accountImport),
				Flags: []cli.Flag{
					utils.DbTypeFlag,
					utils.NoPartitionedDBFlag,
					utils.NumStateTriePartitionsFlag,
					utils.LevelDBCompressionTypeFlag,
					utils.DataDirFlag,
					utils.KeyStoreDirFlag,
					utils.PasswordFileFlag,
					utils.LightKDFFlag,
				},
				ArgsUsage: "<keyFile>",
				Description: `
    klay 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:

    klay account import [options] <keyfile>

Note:
As you can directly copy your encrypted accounts to another klay instance,
this import mechanism is not needed when you transfer an account between
nodes.
