Struct KeyAes256 

pub struct KeyAes256 { /* private fields */ }

KeyAes256 represents an AES-256 encryption key used with the Customer-Supplied Encryption Keys (CSEK) feature.

This key must be exactly 32 bytes in length and should be provided in its raw (unencoded) byte format.

Examples

Creating a KeyAes256 instance from a valid byte slice:

let raw_key_bytes: [u8; 32] = [0x42; 32]; // Example 32-byte key
let key_aes_256 = KeyAes256::new(&raw_key_bytes)?;

Handling an error for an invalid key length:

let invalid_key_bytes: &[u8] = b"too_short_key"; // Less than 32 bytes
let result = KeyAes256::new(invalid_key_bytes);

assert!(matches!(result, Err(KeyAes256Error::InvalidLength)));

Implementations

impl KeyAes256

pub fn new(key: &[u8]) -> Result<Self, KeyAes256Error>

Attempts to create a new KeyAes256.

This conversion will succeed only if the input slice is exactly 32 bytes long.

Example

let raw_key_bytes: [u8; 32] = [0x42; 32]; // Example 32-byte key
let key_aes_256 = KeyAes256::new(&raw_key_bytes)?;
