Struct aead::stream::Encryptor

pub struct Encryptor<A, S>where
    A: AeadInPlace,
    S: StreamPrimitive<A>,
    A::NonceSize: Sub<<S as StreamPrimitive<A>>::NonceOverhead>,
    NonceSize<A, S>: ArrayLength<u8>,{ /* private fields */ }

Available on crate feature stream only.

Stateful STREAM object which can encrypt AEAD messages one-at-a-time.

This corresponds to the ℰ STREAM encryptor object as defined in the paper Online Authenticated-Encryption and its Nonce-Reuse Misuse-Resistance.

Implementations

impl<A, S> Encryptor<A, S>where A: AeadInPlace, S: StreamPrimitive<A>, A::NonceSize: Sub<<S as StreamPrimitive<A>>::NonceOverhead>, NonceSize<A, S>: ArrayLength<u8>,

pub fn new(key: &Key<A>, nonce: &Nonce<A, S>) -> Selfwhere A: KeyInit, S: NewStream<A>,

Create a ℰ STREAM encryptor object from the given AEAD key and nonce.

pub fn from_aead(aead: A, nonce: &Nonce<A, S>) -> Selfwhere A: KeyInit, S: NewStream<A>,

Create a ℰ STREAM encryptor object from the given AEAD primitive.

pub fn from_stream_primitive(stream: S) -> Self

Create a ℰ STREAM encryptor object from the given STREAM primitive.

pub fn encrypt_next<'msg, 'aad>( &mut self, payload: impl Into<Payload<'msg, 'aad>> ) -> Result<Vec<u8>>

Available on crate feature alloc only.

Use the underlying AEAD to encrypt the next AEAD message in this STREAM, returning the result as a Vec.

pub fn encrypt_next_in_place( &mut self, associated_data: &[u8], buffer: &mut dyn Buffer ) -> Result<()>

Use the underlying AEAD to encrypt the next AEAD message in this STREAM in-place.

pub fn encrypt_last<'msg, 'aad>( self, payload: impl Into<Payload<'msg, 'aad>> ) -> Result<Vec<u8>>

Available on crate feature alloc only.

Use the underlying AEAD to encrypt the last AEAD message in this STREAM, consuming the ℰ STREAM encryptor object in order to prevent further use.

pub fn encrypt_last_in_place( self, associated_data: &[u8], buffer: &mut dyn Buffer ) -> Result<()>

Use the underlying AEAD to encrypt the last AEAD message in this STREAM in-place, consuming the ℰ STREAM encryptor object in order to prevent further use.
