Struct OpeningKeyPreparedNonce

pub struct OpeningKeyPreparedNonce<'a, N: NonceSequence> {
    key: &'a mut OpeningKey<N>,
    nonce: Nonce,
}

A key operation with a precomputed nonce from a key’s associated NonceSequence.

Fields

key: &'a mut OpeningKey<N>

nonce: Nonce

Implementations

impl<'a, N: NonceSequence> OpeningKeyPreparedNonce<'a, N>

fn new(key: &'a mut OpeningKey<N>) -> Result<Self, Unspecified>

impl<N: NonceSequence> OpeningKeyPreparedNonce<'_, N>

pub fn nonce(&self) -> &Nonce

Returns the prepared Nonce that is used for key methods invoked on Self.

impl<N: NonceSequence> OpeningKeyPreparedNonce<'_, N>

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

where A: AsRef<[u8]>,

Authenticates and decrypts (“opens”) data in place.

See OpeningKey::open_in_place for additional API information.

Errors

error::Unspecified when ciphertext is invalid. In this case, in_out may have been overwritten in an unspecified way.

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

where A: AsRef<[u8]>,

Authenticates and decrypts (“opens”) data in place, with a shift.

See OpeningKey::open_within for additional API information.

Errors

error::Unspecified when ciphertext is invalid. In this case, in_out may have been overwritten in an unspecified way.

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

Formats the value using the given formatter.
