Struct SymmetricKey 

pub struct SymmetricKey(/* private fields */);

Symmetric encryption key that is automatically zeroized

Implementations

impl SymmetricKey

pub fn generate() -> Self

Generate a new random symmetric key

pub fn from_bytes(bytes: [u8; 32]) -> Result<Self>

Create key from bytes

pub fn as_bytes(&self) -> &[u8; 32]

Get key bytes (use with caution)

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

Encrypt data with associated authenticated data

pub fn decrypt(&self, data: &EncryptedData, aad: &[u8]) -> Result<Vec<u8>>

Decrypt data and verify associated authenticated data

Trait Implementations

impl Clone for SymmetricKey

fn clone(&self) -> SymmetricKey

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SymmetricKey

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SymmetricKey

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Drop for SymmetricKey

fn drop(&mut self)

Executes the destructor for this type.

impl Serialize for SymmetricKey

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl Zeroize for SymmetricKey

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.
