It is available not only std environment but also no_std. Also Intel SGX is supported. If you feel interested, visit my repository to see other examples, check algorithms used, and give a star

#[derive(Debug, Serialize, Deserialize)]

struct Message {

    content: String,

    sender: String,

// This is the trick!

impl SerdeEncryptSharedKey for Message {}

let shared_key = [0u8; 32]; // or read from your filesystem?

let msg = Message {

    content: "I  you.".to_string(),

    sender: "Alice".to_string(),

// Encrypt and serialize the serde struct

let encrypted_message = msg.encrypt(&shared_key)?;

let serialized_encrypted_message: Vec<u8> = encrypted_message.serialize()?;

// Deserialize and decrypt

let encrypted_message = EncryptedMessage::deserialize(serialized_encrypted_message)?;

let msg = Message::decrypt_owned(&encrypted_message, &shared_key)

-------------------------

SerdeEncryptPublicKey trait is also provided mainly for secure shared-key exchange (using ECDH algorithm internally).
