Struct LessSafeKey

pub struct LessSafeKey { /* private fields */ }

Immutable keys for use in situations where OpeningKey/SealingKey and NonceSequence cannot reasonably be used.

Prefer to use OpeningKey/SealingKey and NonceSequence when practical.

Implementations

impl LessSafeKey

pub fn new(key: UnboundKey) -> Self

Constructs a LessSafeKey.

pub fn open_in_place_separate_tag<'in_out, A>( &self, nonce: Nonce, aad: Aad<A>, tag: Tag, in_out: &'in_out mut [u8], ciphertext: RangeFrom<usize>, ) -> Result<&'in_out mut [u8], Unspecified>

where A: AsRef<[u8]>,

Like open_in_place, except the authentication tag is passed separately.

pub fn open_in_place<'in_out, A>( &self, nonce: Nonce, aad: Aad<A>, in_out: &'in_out mut [u8], ) -> Result<&'in_out mut [u8], Unspecified>

where A: AsRef<[u8]>,

Like super::OpeningKey::open_in_place(), except it accepts an arbitrary nonce.

nonce must be unique for every use of the key to open data.

pub fn open_within<'in_out, A>( &self, nonce: Nonce, aad: Aad<A>, in_out: &'in_out mut [u8], ciphertext_and_tag: RangeFrom<usize>, ) -> Result<&'in_out mut [u8], Unspecified>

where A: AsRef<[u8]>,

Like super::OpeningKey::open_within(), except it accepts an arbitrary nonce.

nonce must be unique for every use of the key to open data.

pub fn seal_in_place_append_tag<A, InOut>( &self, nonce: Nonce, aad: Aad<A>, in_out: &mut InOut, ) -> Result<(), Unspecified>

where A: AsRef<[u8]>, InOut: AsMut<[u8]> + for<'in_out> Extend<&'in_out u8>,

Like super::SealingKey::seal_in_place_append_tag(), except it accepts an arbitrary nonce.

nonce must be unique for every use of the key to seal data.

pub fn seal_in_place_separate_tag<A>( &self, nonce: Nonce, aad: Aad<A>, in_out: &mut [u8], ) -> Result<Tag, Unspecified>

where A: AsRef<[u8]>,

Like super::SealingKey::seal_in_place_separate_tag(), except it accepts an arbitrary nonce.

nonce must be unique for every use of the key to seal data.

pub fn algorithm(&self) -> &'static Algorithm

The key’s AEAD algorithm.

Trait Implementations

impl Clone for LessSafeKey

fn clone(&self) -> LessSafeKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LessSafeKey

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

Formats the value using the given formatter.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
