Struct fog_crypto::lockbox::DataLockbox

pub struct DataLockbox(_);

General encrypted data.

This must be decrypted by the matching recipient, which will return a Vec<u8> on success. It can either be decrypted on its own or through a Vault. In both cases, the data is returned without being stored anywhere.

When decoding, a reference to the data is first created: DataLockboxRef, which can then be converted with to_owned to create this struct.

See: StreamKey::decrypt_data, LockKey::decrypt_data, and Vault::decrypt_data.

Example

Using a StreamKey for decryption:

// We have `enc`, a byte vector containing a lockbox
let dec_lockbox: DataLockbox = DataLockboxRef::from_bytes(&enc[..])?.to_owned();
let recipient: LockboxRecipient = dec_lockbox.recipient();
// ...
// Retrieve the key by looking up recipient
// ...
let plaintext: Vec<u8> = key.decrypt_data(&dec_lockbox)?;

Methods from Deref<Target = DataLockboxRef>

pub fn as_parts(&self) -> LockboxParts<'_>

Decompose the lockbox into its component parts.

pub fn version(&self) -> u8

Get the stream encryption version.

pub fn recipient(&self) -> LockboxRecipient

Get the target recipient who can decrypt this.

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

The raw bytestream, suitable for serialization.

Trait Implementations

impl Borrow<DataLockboxRef> for DataLockbox

fn borrow(&self) -> &DataLockboxRef

Immutably borrows from an owned value.

impl Clone for DataLockbox

fn clone(&self) -> DataLockbox

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DataLockbox

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

Formats the value using the given formatter.

impl Deref for DataLockbox

type Target = DataLockboxRef

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'de> Deserialize<'de> for DataLockbox

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for DataLockbox

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<DataLockbox> for DataLockbox

fn eq(&self, other: &DataLockbox) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for DataLockbox

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

Serialize this value into the given Serde serializer.
