impl Aes256GcmEncryptor

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

Create a new encryptor with the given key.

Errors

Returns an error if the key is not 32 bytes.

pub fn generate_key() -> [u8; 32]

Generate a new random encryption key.

pub fn generate_nonce() -> [u8; 12]

Generate a random nonce.

pub fn encrypt(&self, plaintext: &[u8]) -> Result<EncryptedData>

Encrypt data with a random nonce.

Errors

Returns an error if encryption fails.

pub fn encrypt_with_nonce( &self, plaintext: &[u8], nonce: &[u8; 12], ) -> Result<EncryptedData>

Encrypt data with a specific nonce.

Errors

Returns an error if encryption fails.

pub fn decrypt(&self, ciphertext: &[u8], nonce: &[u8]) -> Result<Vec<u8>>

Decrypt data.

Errors

Returns an error if decryption fails (wrong key or tampered data).
