impl BlockCipher for CryptoSym

fn encrypt_message( signer_sk: &[u8; 32], receiver_pk: &[u8; 32], msg: &[u8], ) -> Result<Vec<u8>>

Encode a message text with AES-GCM algorithm using the signer’s the PrivateKey and receiver’s PublicKey.

Inputs

• signer_sk: The signer’s private key.

• receiver_pk: The receiver’s public key.

• msg: Message to encrypt.

Returns

A Result whose okay value is an encrypt message Vec<u8> or whose error value is an failure::Error describing the error that occurred.

fn decrypt_message( receiver_sk: &[u8; 32], signer_pk: &[u8; 32], enc_msg: &[u8], ) -> Result<Vec<u8>>

Decrypt a message text with AES-GCM algorithm using the receiver’s the PrivateKey and signer’s PublicKey.

Inputs

• receiver_sk: The receiver’s private key.

• signer_pk: The signer’s public key.

• enc_msg: Message encrypted.

Example

use std::str::FromStr;
use symbol_crypto_core::{PrivateKey, PublicKey,decrypt_message };

let receiver_sk = PrivateKey::from_str("A22A4BBF126A2D7D7ECE823174DFD184C5DE0FDE4CB2075D30CFA409F7EF8908").unwrap();
let signer_pk = PublicKey::from_str("3FD283D8543C12B81917C154CDF4EFD3D48E553E6D7BC77E29CB168138CED17D").unwrap();

let encrypt_text_vec = [
    125, 59, 126, 248, 124, 129, 157, 100, 111, 84, 49, 163, 111, 68, 22, 137, 75, 132, 135,
    217, 251, 158, 115, 74, 226, 172, 200, 208, 33, 183, 110, 103, 107, 170, 52, 174, 192, 110,

    184, 66,
];

let decrypted_text = decrypt_message( receiver_sk.as_fixed_bytes(), signer_pk.as_fixed_bytes(), &encrypt_text_vec).unwrap();

Returns

A Result whose okay value is an decrypted message Vec<u8> or whose error value is an failure::Error describing the error that occurred.
