Struct Aes256Gcm 

pub struct Aes256Gcm { /* private fields */ }

Implementations

impl Aes256Gcm

pub const KEY_SIZE: usize = 32

pub fn new(key: &[u8; 32]) -> Self

Create a new Aes256Gcm instance from a 32-byte key.

Precomputes the target-specific round keys and GHASH powers (H, H², H³, H⁴) using software GF(2¹²⁸) multiplication, so new() is safe on any CPU and does not require hardware feature detection.
