Struct KeyPair

pub struct KeyPair { /* private fields */ }

The main interface used for reading and writing nkey-encoded key pairs, including seeds and public keys.

Implementations

impl KeyPair

pub fn new(kp_type: KeyPairType) -> KeyPair

Creates a new key pair of the given type.

NOTE: This is not available if using on a wasm32-unknown-unknown target due to the lack of rand support. Use new_from_raw instead

pub fn new_from_raw( kp_type: KeyPairType, random_bytes: [u8; 32], ) -> Result<KeyPair, Error>

Create a new keypair using a pre-existing set of random bytes.

Returns an error if there is an issue using the bytes to generate the key NOTE: These bytes should be generated from a cryptographically secure random source.

pub fn new_user() -> KeyPair

Creates a new user key pair with a seed that has a U prefix

NOTE: This is not available if using on a wasm32-unknown-unknown target due to the lack of rand support. Use new_from_raw instead

pub fn new_account() -> KeyPair

Creates a new account key pair with a seed that has an A prefix

NOTE: This is not available if using on a wasm32-unknown-unknown target due to the lack of rand support. Use new_from_raw instead

pub fn new_operator() -> KeyPair

Creates a new operator key pair with a seed that has an O prefix

NOTE: This is not available if using on a wasm32-unknown-unknown target due to the lack of rand support. Use new_from_raw instead

pub fn new_cluster() -> KeyPair

Creates a new cluster key pair with a seed that has the C prefix

NOTE: This is not available if using on a wasm32-unknown-unknown target due to the lack of rand support. Use new_from_raw instead

pub fn new_server() -> KeyPair

Creates a new server key pair with a seed that has the N prefix

NOTE: This is not available if using on a wasm32-unknown-unknown target due to the lack of rand support. Use new_from_raw instead

pub fn new_module() -> KeyPair

Creates a new module (e.g. WebAssembly) key pair with a seed that has the M prefix

NOTE: This is not available if using on a wasm32-unknown-unknown target due to the lack of rand support. Use new_from_raw instead

pub fn new_service() -> KeyPair

Creates a new service / service provider key pair with a seed that has the V prefix

NOTE: This is not available if using on a wasm32-unknown-unknown target due to the lack of rand support. Use new_from_raw instead

pub fn public_key(&self) -> String

Returns the encoded, human-readable public key of this key pair

pub fn sign(&self, input: &[u8]) -> Result<Vec<u8>, Error>

Attempts to sign the given input with the key pair’s seed

pub fn verify(&self, input: &[u8], sig: &[u8]) -> Result<(), Error>

Attempts to verify that the given signature is valid for the given input

pub fn seed(&self) -> Result<String, Error>

Attempts to return the encoded, human-readable string for this key pair’s seed. Remember that this value should be treated as a secret. Do not store it for any longer than necessary

pub fn from_public_key(source: &str) -> Result<KeyPair, Error>

Attempts to produce a public-only key pair from the given encoded public key string

pub fn from_seed(source: &str) -> Result<KeyPair, Error>

Attempts to produce a full key pair from the given encoded seed string

pub fn key_pair_type(&self) -> KeyPairType

Returns the type of this key pair.

Trait Implementations

impl Clone for KeyPair

fn clone(&self) -> KeyPair

Returns a copy of the value.

Performs copy-assignment from source.

impl Debug for KeyPair

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>
