Struct LockLockboxRef

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

An reference to an encrypted LockKey.

This must be decrypted by the matching recipient, which will return the LockKey on success. It can either be decrypted on its own, returning a temporary LockKey, or through a Vault, which will store the LockKey.

This is only a reference to an encrypted payload. The owned version is LockLockbox.

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

Example

Using a StreamKey for decryption:

// We have `enc`, a byte vector containing a lockbox
let dec_lockbox: &LockLockboxRef = LockLockboxRef::from_bytes(&enc[..])?;
let recipient: LockboxRecipient = dec_lockbox.recipient();
// ...
// Retrieve the key by looking up recipient
// ...
let dec_key: LockKey = key.decrypt_lock_key(&dec_lockbox)?;

Implementations

impl LockLockboxRef

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.

pub fn from_bytes(buf: &[u8]) -> Result<&LockLockboxRef, CryptoError>

Trait Implementations

impl Borrow<LockLockboxRef> for LockLockbox

fn borrow(&self) -> &LockLockboxRef

Immutably borrows from an owned value.

impl Debug for LockLockboxRef

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

Formats the value using the given formatter.

impl<'de, 'a> Deserialize<'de> for &'a LockLockboxRef

where 'de: 'a,

fn deserialize<D>( deserializer: D, ) -> Result<&'a LockLockboxRef, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a> From<&'a LockLockboxRef> for ValueRef<'a>

fn from(v: &'a LockLockboxRef) -> Self

Converts to this type from the input type.

impl Hash for LockLockboxRef

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

where __H: Hasher,

Feeds this value into the given Hasher.

impl PartialEq for LockLockboxRef

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for LockLockboxRef

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

where S: Serializer,

Serialize this value into the given Serde serializer.

impl ToOwned for LockLockboxRef

type Owned = LockLockbox

The resulting type after obtaining ownership.

fn to_owned(&self) -> <LockLockboxRef as ToOwned>::Owned

Creates owned data from borrowed data, usually by cloning.

fn clone_into(&self, target: &mut Self::Owned)

Uses borrowed data to replace owned data, usually by cloning.

impl<'a> TryFrom<ValueRef<'a>> for &'a LockLockboxRef

type Error = ValueRef<'a>

The type returned in the event of a conversion error.

fn try_from(v: ValueRef<'a>) -> Result<Self, Self::Error>

Performs the conversion.
