Struct lib3h_crypto_api::FakeCryptoSystem

pub struct FakeCryptoSystem {}

WARNING THIS IS NOT SECURE!! This is a fake crypto system to give hints for implementing real systems. The functions here mimic a real crypto system, but are doing trivial things. Do not use this for any real systems. Even the random functions are fake, and produce poor results.

Trait Implementations

impl CryptoRandom for FakeCryptoSystem

fn randombytes_buf<OutputBuffer: Buffer>(
    buffer: &mut OutputBuffer
) -> CryptoResult<()>

Fill the output buffer with cryptographicly secure random bytes

impl CryptoSignature for FakeCryptoSystem

const SIGN_SEED_BYTES: usize

byte length of seed for generating signature keypairs

const SIGN_PUBLIC_KEY_BYTES: usize

byte length of signature public keys

const SIGN_SECRET_KEY_BYTES: usize

byte length of signature secret keys

const SIGN_BYTES: usize

byte length of signatures

fn sign_seed_keypair<SeedBuffer: Buffer, PublicKeyBuffer: Buffer, SecretKeyBuffer: Buffer>(
    seed: &SeedBuffer,
    public_key: &mut PublicKeyBuffer,
    secret_key: &mut SecretKeyBuffer
) -> CryptoResult<()>

Given a seed buffer of SIGN_SEED_BYTES length, produce a public key of SIGN_PUBLIC_KEY_BYTES length, and an associated secret key of SIGN_SECRET_KEY_BYTES length.

fn sign_keypair<PublicKeyBuffer: Buffer, SecretKeyBuffer: Buffer>(
    public_key: &mut PublicKeyBuffer,
    secret_key: &mut SecretKeyBuffer
) -> CryptoResult<()>

Produce a public key of SIGN_PUBLIC_KEY_BYTES length, and an associated secret key of SIGN_SECRET_KEY_BYTES length.

fn sign<SignatureBuffer: Buffer, MessageBuffer: Buffer, SecretKeyBuffer: Buffer>(
    signature: &mut SignatureBuffer,
    message: &MessageBuffer,
    secret_key: &SecretKeyBuffer
) -> CryptoResult<()>

Generate a cryptographic / digital signature for a message with the given secret key. The signature bytes are placed in the signature parameter.

fn sign_verify<SignatureBuffer: Buffer, MessageBuffer: Buffer, PublicKeyBuffer: Buffer>(
    signature: &SignatureBuffer,
    message: &MessageBuffer,
    public_key: &PublicKeyBuffer
) -> CryptoResult<bool>

Given a public key, verify that signature was generated for the supplied message data with the associated secret key.
