Struct AesCipher 

pub struct AesCipher { /* private fields */ }

Stores expanded AES round keys for block encryption/decryption.

Implementations

impl AesCipher

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

Builds an AES cipher for 128/192/256-bit keys.

Arguments

• key: AES key bytes (16, 24, or 32 bytes).

Returns

Arguments

• block: Mutable 16-byte block to encrypt in place.

pub fn decrypt_block(&self, block: &mut [u8; 16])

Decrypts one 16-byte block in place using AES inverse rounds.

Arguments

• block: Mutable 16-byte block to decrypt in place.
