= 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 -n <msg> | subkey sign <seed,mnemonic> OUTPUT: a69da4a6ccbf81dbbbfad235fa12cf8528c18012b991ae89214de8d20d29c1280576ced6eb38b7406d1b7e03231df6dd4a5257546ddad13259356e1c3adfb509 ``` === Verifying a signature ```bash echo -n <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.
