Implementations§

Source §

impl AtRestEncryptor

Source

pub fn new( algorithm: EncryptionAlgorithm, key: Vec<u8>, key_id: String, ) -> Result<Self>

Create a new encryptor with the given algorithm and key.

Source

pub fn generate_key(algorithm: EncryptionAlgorithm) -> Vec<u8> ⓘ

Generate a random key for the given algorithm.

Source

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

Encrypt data.

Source

pub fn decrypt(&self, encrypted: &EncryptedData) -> Result<Vec<u8>>

Decrypt data.

Source

pub fn encrypt_in_place( &self, buffer: &mut Vec<u8>, aad: Option<&[u8]>, ) -> Result<EncryptionMetadata>

Encrypt data in place (overwrites input buffer).

Source

pub fn algorithm(&self) -> EncryptionAlgorithm

Get the algorithm used by this encryptor.

Source

pub fn key_id(&self) -> &str

Get the key ID.
