= Subkey
|
|
|
|
Subkey is a commandline utility included with Substrate that generates or restores Substrate keys.
|
|
|
|
`subkey` will use the http://wiki.polkadot.network/en/latest/polkadot/learn/cryptography/#keypairs-and-signing[sr25519] cryptography by default. If you need to use the older ed25519 cryptography to generate or restore your key pass the `--ed25519` flag to any of the commands.
|
|
|
|
== Usage
|
|
|
|
=== Generate a random account
|
|
|
|
```bash
|
|
subkey generate
|
|
```
|
|
|
|
Will output a mnemonic phrase and give you the seed, public key, and address of a new account. DO NOT SHARE your mnemonic or seed with ANYONE it will give them access to your funds. If someone is making a transfer to you they will only need your **Address**.
|
|
|
|
=== Inspecting a key
|
|
|
|
You can inspect a given URI (mnemonic, seed, public key, or address) and recover the public key and the address.
|
|
|
|
```bash
|
|
subkey inspect <mnemonic,seed,pubkey,address>
|
|
|
|
OUTPUT:
|
|
Public key (hex): 0x461edcf1ba99e43f50dec4bdeb3d1a2cf521ad7c3cd0eeee5cd3314e50fd424c
|
|
Address (SS58): 5DeeNqcAcaHDSed2HYnqMDK7JHcvxZ5QUE9EKmjc5snvU6wF
|
|
```
|
|
|
|
=== Signing
|
|
|
|
`subkey` expects a message to come in on STDIN, one way to sign a message would look like this:
|
|
|
|
```bash
|
|
echo <msg> | subkey sign <seed,mnemonic>
|
|
|
|
OUTPUT:
|
|
a69da4a6ccbf81dbbbfad235fa12cf8528c18012b991ae89214de8d20d29c1280576ced6eb38b7406d1b7e03231df6dd4a5257546ddad13259356e1c3adfb509
|
|
```
|
|
|
|
=== Verifying a signature
|
|
|
|
```bash
|
|
echo <msg> | subkey verify <sig> <address>
|
|
|
|
OUTPUT:
|
|
Signature verifies correctly.
|
|
```
|
|
|
|
=== Using the vanity generator
|
|
|
|
You can use the included vanity generator to find a seed that provides an address which includes the desired pattern. Be warned, depending on your hardware this may take a while.
|
|
|
|
```bash
|
|
subkey vanity 1337
|
|
```
|
|
|
|
=== Signing a transaction
|
|
|
|
Sign a transaction from an encoded `Call`.
|
|
|
|
```bash
|
|
subkey sign-transaction \
|
|
--call <call-as-hex> \
|
|
--nonce 0 \
|
|
--suri <secret-uri> \
|
|
--password <password> \
|
|
--prior-block-hash <prior-block-hash-as-hex>
|
|
```
|
|
|
|
Will output a signed and encoded `UncheckedMortalCompactExtrinsic` as hex.
