Crate sodiumbox 

Pure Rust implementation of libsodium’s sealed box encryption/decryption.

This crate provides a standalone implementation of the sealed box functionality from libsodium (NaCl) using only pure Rust cryptographic libraries. It is fully compatible with sealed boxes created by libsodium/sodiumoxide.

Features

• seal: Create a sealed box for a recipient’s public key
• open_sealed_box: Open a sealed box using the recipient’s keypair
• Pure Rust implementation with no C dependencies

Structs

PublicKey

A Diffie-Hellman public key

StaticSecret

A Diffie-Hellman secret key that can be used to compute multiple SharedSecrets.

Constants

PUBLICKEYBYTES

The length of a Curve25519 public key in bytes (for compatibility with sealed box format)

Functions

generate_keypair

Generate a new X25519 keypair for use with sealed box operations

open_sealed_box

Opens a sealed box using RustCrypto libraries.

public_key_from_bytes

Convenience function to convert a public key from bytes to the PublicKey type

seal

Creates a sealed box for a message using a recipient’s public key.

secret_key_from_bytes

Convenience function to convert a secret key from bytes to the StaticSecret type
