Sealed boxes for Rust/WebAssembly

This Rust crate provides libsodium sealed boxes for WebAssembly.

Usage:

// Recipient: create a new key pair
let recipient_kp = sealed_box::KeyPair::create();

//  Sender: encrypt the message for the recipient whose public key is recipient_kp.pk
let msg = b"test";
let ciphertext = sealed_box::seal(msg, recipient_kp.pk);

// Recipient: decrypt the ciphertext using the key pair
let decrypted_msg = sealed_box::open(&ciphertext, &recipient_kp).unwrap();

assert_eq!(msg[..], decrypted_msg);

Compile with cargo wasi.
