Struct aez::Aez

#[repr(C)]
pub struct Aez(_);

Methods

impl Aez

pub fn new(key: &[u8]) -> Self

Create a new Aez instance keyed with variable length. Aez recommends a 48 byte key.

pub fn encrypt<'a>(
    &self,
    n: &[u8],
    ad: impl Into<Option<&'a [u8]>>,
    pt: &[u8],
    ct: &mut [u8]
)

Encrypt a message. The nonce length must be 1..=16. The ciphertext may be up to 16 bytes larger than the message, these extra bytes add authentication. Additionally, the ciphertext must not be larger than 2^32 - 1.

Will panic if the above constraints are broken.

    n: &[u8],
    ad: impl Into<Option<&'a [u8]>>,
    ct: &[u8],
    pt: &mut [u8]
) -> Result<(), ()>

Decrypt a message. The nonce length must be 1..=16. The ciphertext may be up to 16 bytes larger than the message, these extra bytes add authentication. Additionally, the ciphertext must not be larger than 2^32 - 1.

Will panic if the above constraints are broken.
