# Function openssl::symm::encrypt [−] [src]

    pub fn encrypt(
        t: Cipher,
        key: &[u8],
        iv: Option<&[u8]>,
        data: &[u8]
    ) -> Result<Vec<u8>, ErrorStack>

Encrypts data in one go, and returns the encrypted data.

Data is encrypted using the specified cipher type `t` in encrypt mode with the specified `key` and initailization vector `iv`. Padding is enabled.

This is a convenient interface to `Crypter` to encrypt all data in one go. To encrypt a stream of data increamentally , use `Crypter` instead.

# Examples

Encrypt data in AES128 CBC mode

    use openssl::symm::{encrypt, Cipher};

    let cipher = Cipher::aes_128_cbc();
    let data = b"Some Crypto Text";
    let key = b"\x00\x01\x02\x03\x04\x05\x06\x07\x08\x09\x0A\x0B\x0C\x0D\x0E\x0F";
    let iv = b"\x00\x01\x02\x03\x04\x05\x06\x07\x00\x01\x02\x03\x04\x05\x06\x07";
    let ciphertext = encrypt(
        cipher,
        key,
        Some(iv),
        data).unwrap();

    assert_eq!(
        b"\xB4\xB9\xE7\x30\xD6\xD6\xF7\xDE\x77\x3F\x1C\xFF\xB3\x3E\x44\x5A\x91\xD7\x27\x62\x87\x4D\
