Hive Memo
Hive Memo is a Rust crate designed for encrypting and decrypting memos using elliptic curve cryptography (ECC) and AES-256-CBC encryption, taking @hiveo/dhive's memo encryption and decryption methods into account.
Features
-
Key Management
- Parse and validate WIF (Wallet Import Format) private keys.
- Handle public keys in Hive format (
STM
prefixed). - Derive public keys from private keys.
-
Encryption & Decryption
- Encrypt memos using AES-256-CBC with shared secrets derived from ECDH.
Installation
Add hive_memo
to your Cargo.toml
:
[dependencies]
hive_memo = "0.1.0"
OR
cargo add hive_memo
Usage
Encryption
use hive_memo::keys::{wif_to_secret_key, public_key_from_string};
use hive_memo::encryption::encrypt_memo;
use std::error::Error;
fn main() {
// Sender's WIF private key
let sender_private_wif = "5KV4qZ1obXQPwUQqitD5Tx86Writ4tbeDAo68WLXhcU3ZaHR1M7";
// Receiver's public key in Hive format
let receiver_public_key_str = "STM5PQVrcekY3psFdYxRDXtYRNNWsPjeHtTvfhUtKaiADPvRqSVYM";
// Convert WIF to SecretKey
let sender_private_key = wif_to_secret_key(sender_private_wif)?;
// Convert Hive public key string to PublicKey
let receiver_public_key = public_key_from_string(receiver_public_key_str)?;
let memo = "#This is a secure memo";
// Encrypt the memo
let encrypted_memo = encrypt_memo(&sender_private_key, &receiver_public_key, memo)?;
println!("Encrypted Memo: {}", encrypted_memo);
}
Decryption
use hive_memo::keys::wif_to_secret_key;
use hive_memo::encryption::decrypt_memo;
use std::error::Error;
fn main() {
// Receiver's WIF private key
let receiver_private_wif = "5KV4qZ1obXQPwUQqitD5Tx86Writ4tbeDAo68WLXhcU3ZaHR1M7";
// Encrypted memo string
let encrypted_memo = "#<Base58EncodedEncryptedMemo>";
// Convert WIF to SecretKey
let receiver_private_key = wif_to_secret_key(receiver_private_wif)?;
// Decrypt the memo
let decrypted_memo = decrypt_memo(&receiver_private_key, encrypted_memo)?;
println!("Decrypted Memo: {}", decrypted_memo);
}
