Struct CryptoEngine 

pub struct CryptoEngine { /* private fields */ }

Cryptographic engine for encrypting and signing diffs

Implementations

impl CryptoEngine

pub fn new() -> Self

Create a new crypto engine with random keys

pub fn from_keys(symmetric_key: [u8; 32], signing_key_bytes: [u8; 32]) -> Self

Create from existing keys

pub fn new_with_seed(seed: [u8; 32]) -> Self

Create from seed (derives keys deterministically)

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

Get the public key for verification

pub fn encrypt_diff(&self, diff: &CognitiveDiff) -> Result<EncryptedPayload>

Encrypt and sign a cognitive diff

pub fn sign(&self, data: &[u8]) -> Signature

Sign arbitrary data

pub fn decrypt_diff(&self, payload: &EncryptedPayload) -> Result<CognitiveDiff>

Decrypt and verify a payload

Trait Implementations

impl Default for CryptoEngine

fn default() -> Self

Returns the “default value” for a type.
