Function crypto_ext::symmetric::encryption::encrypt

pub fn encrypt(
    params: EncryptionParameters,
    data_to_encrypt: &[u8],
    associated_data: &[u8]
) -> Result<Vec<u8>, String>

Encrypts given byte array

Examples

    use crypto_ext::symmetric::encryption::{decrypt, encrypt, get_decryption_params, get_encryption_params, setup};

    #[test]
    fn encryption() {
        let data = "some data to encrypt".as_bytes();
        let associated_data = "some unencrypted data that needs to be sent along the encrypted data and won't be changed during transmission by a hacker".as_bytes();

        // path needs to be accessible by user with write permission for initial setup
        // ideally for each encryption you need to setup unique folder for AES key and nonce
        // do not reuse same setup with Encryption and Decryption parameters for multiple encryptions
        let params_path = "/test/encryption_parameters/";


        let (encryption_params, decryption_params) = setup(Some(params_path)).unwrap();

        let encrypted = encrypt(encryption_params, data, associated_data).unwrap();

        let decrypted = decrypt(decryption_params, encrypted.as_slice(), associated_data).unwrap();

        assert_eq!(data, decrypted);

    }
