Struct bamboo_rs_core::SecretKey

pub struct SecretKey(_);

An EdDSA secret key.

Instances of this secret are automatically overwritten with zeroes when they fall out of scope.

Implementations

impl SecretKey

pub fn to_bytes(&self) -> [u8; 32]

Convert this secret key to a byte array.

pub fn as_bytes(&'a self) -> &'a [u8; 32]

View this secret key as a byte array.

pub fn from_bytes(bytes: &[u8]) -> Result<SecretKey, Error>

Construct a SecretKey from a slice of bytes.

Example

use ed25519_dalek::SecretKey;
use ed25519_dalek::SECRET_KEY_LENGTH;
use ed25519_dalek::SignatureError;

let secret_key_bytes: [u8; SECRET_KEY_LENGTH] = [
   157, 097, 177, 157, 239, 253, 090, 096,
   186, 132, 074, 244, 146, 236, 044, 196,
   068, 073, 197, 105, 123, 050, 105, 025,
   112, 059, 172, 003, 028, 174, 127, 096, ];

let secret_key: SecretKey = SecretKey::from_bytes(&secret_key_bytes)?;

Returns

A Result whose okay value is an EdDSA SecretKey or whose error value is an SignatureError wrapping the internal error that occurred.

pub fn generate<T>(csprng: &mut T) -> SecretKey where
    T: CryptoRng + RngCore, 

Generate a SecretKey from a csprng.

Example

extern crate rand;
extern crate ed25519_dalek;

use rand::rngs::OsRng;
use ed25519_dalek::PublicKey;
use ed25519_dalek::SecretKey;
use ed25519_dalek::Signature;

let mut csprng = OsRng{};
let secret_key: SecretKey = SecretKey::generate(&mut csprng);

Afterwards, you can generate the corresponding public:

let public_key: PublicKey = (&secret_key).into();

Input

A CSPRNG with a fill_bytes() method, e.g. rand::OsRng

Trait Implementations

impl AsRef<[u8]> for SecretKey

pub fn as_ref(&self) -> &[u8]

Performs the conversion.

impl Debug for SecretKey

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

Formats the value using the given formatter.

impl<'d> Deserialize<'d> for SecretKey

pub fn deserialize<D>(
    deserializer: D
) -> Result<SecretKey, <D as Deserializer<'d>>::Error> where
    D: Deserializer<'d>, 

Deserialize this value from the given Serde deserializer.

impl Drop for SecretKey

pub fn drop(&mut self)

Executes the destructor for this type.

impl<'a> From<&'a SecretKey> for PublicKey

pub fn from(secret_key: &SecretKey) -> PublicKey

Derive this public key from its corresponding SecretKey.

impl Serialize for SecretKey

pub fn serialize<S>(
    &self,
    serializer: S
) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error> where
    S: Serializer, 

Serialize this value into the given Serde serializer.

impl Zeroize for SecretKey

pub fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.
