Function psa_crypto::operations::cipher::decrypt

pub fn decrypt(
    key_id: Id,
    alg: Cipher,
    ciphertext: &[u8],
    iv: &[u8],
    plaintext: &mut [u8]
) -> Result<usize>

Decrypt a short message with a key

The decrypted message is written in plaintext. The function returns the number of bytes written.

Example

psa_crypto::init().unwrap();
let my_key = generate(attributes, None).unwrap();
let alg = Cipher::Ctr;
let iv = vec![0; 16];
let mut decrypted_message = vec![0; MESSAGE.len()];

let size = decrypt(my_key, alg, &MESSAGE, &iv, &mut decrypted_message).unwrap();
