Function enc_file::encrypt_hashmap

pub fn encrypt_hashmap(
    keymap_plaintext: HashMap<String, String>, 
    password: &str
) -> Result<Vec<u8>, Box<dyn Error>>

Encrypt a given hashmap with a given password using ChaCha20Poly1305. Returns result (Vec)

Examples

use std::collections::HashMap;
use aes_gcm_siv::aead::{generic_array::GenericArray, Aead, NewAead};
use chacha20poly1305::XChaCha20Poly1305;
use enc_file::{encrypt_hashmap};
use serde::{Deserialize, Serialize};

//create example keymap. Keymap constits of key-name and actual-key. Attention: Valid keys for cryptography needs to be 32-chars utf8!
let mut keymap_plaintext: HashMap<String, String> = HashMap::new();
keymap_plaintext.insert("Hello".to_string(), "world".to_string());

//create (extremely insecure) password
let password: String = "Password".to_string();
//encrypt keymap with password
let encrypted: Vec<u8> = encrypt_hashmap(keymap_plaintext.clone(), &password).unwrap();

//test that encrypting 2 times results in different Vec<u8>
let encrypted2: Vec<u8> = encrypt_hashmap(keymap_plaintext, &password).unwrap();
assert_ne!(encrypted, encrypted2);
