Function psa_crypto::operations::asym_encryption::encrypt

pub fn encrypt(
    key_id: Id, 
    alg: AsymmetricEncryption, 
    plaintext: &[u8], 
    salt: Option<&[u8]>, 
    ciphertext: &mut [u8]
) -> Result<usize>

Encrypt a short message with a key pair or public key

The encrypted message is written in ciphertext. The function returns the number of bytes written.

Example

psa_crypto::init().unwrap();
let my_key = generate(attributes, None).unwrap();
let alg = AsymmetricEncryption::RsaPkcs1v15Crypt;
let buffer_size = attributes.asymmetric_encrypt_output_size(alg).unwrap();
let mut encrypted_message = vec![0; buffer_size];

let size = encrypt(my_key,
                     alg,
                     &MESSAGE,
                     None,
                     &mut encrypted_message).unwrap();
encrypted_message.resize(size, 0);
