# Double Ratchet
|
|
|
|
This library provides an implementation of the Double Ratchet algorithm.
|
|
|
|
## Usage
|
|
|
|
```rust
|
|
let shared_secret = [42u8; 32];
|
|
let bob_dh = DhKeyPair::generate();
|
|
|
|
let mut alice = RatchetState::init_sender(shared_secret, bob_dh.public);
|
|
let mut bob = RatchetState::init_receiver(shared_secret, bob_dh);
|
|
|
|
let (ciphertext, header) = alice.encrypt_message(b"Hello Bob!");
|
|
let plaintext = bob.decrypt_message(&ciphertext, header);
|
|
```
|
|
|
|
Run examples,
|
|
|
|
```
|
|
cargo run --example double_ratchet_basic
|
|
```
|
|
|
|
Run Nim FFI example,
|
|
|
|
```bash
|
|
# In the root folder (libchat)
|
|
cargo build --release
|
|
# In ffi-nim-example folder
|
|
nimble run
|
|
```
