Function decrypt_with_aes 

pub fn decrypt_with_aes(
    ciphertext: &[u8],
    key: &[u8; 32],
    iv: &[u8; 16],
) -> Result<Vec<u8>, Box<dyn Error>>

Decrypt a message using AES-256-CBC with a custom IV

Arguments

• ciphertext - The encrypted ciphertext to decrypt
• key - A 32-byte encryption key (must match encryption key)
• iv - A 16-byte initialization vector (must match encryption IV)

Returns

Returns a Result containing the decrypted plaintext as Vec or an error

Example

use askrypt::{encrypt_with_aes, decrypt_with_aes};

let message = b"Hello, World!";
let key = [0u8; 32];
let iv = [0u8; 16];

let ciphertext = encrypt_with_aes(message, &key, &iv).unwrap();
let plaintext = decrypt_with_aes(&ciphertext, &key, &iv).unwrap();
assert_eq!(message, &plaintext[..]);
