Struct Decryptor 

pub struct Decryptor<A, S>
where
    A: AeadInOut,
    S: StreamPrimitive<A>,
    A::NonceSize: Sub<<S as StreamPrimitive<A>>::NonceOverhead>,
    NonceSize<A, S>: ArraySize,
{ /* private fields */ }

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

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

Implementations

impl<A, S> Decryptor<A, S>

where A: AeadInOut, S: StreamPrimitive<A>, A::NonceSize: Sub<<S as StreamPrimitive<A>>::NonceOverhead>, NonceSize<A, S>: ArraySize,

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

where A: KeyInit, S: NewStream<A>,

Create a 𝒟 STREAM decryptor object from the given AEAD key and nonce.

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

where S: NewStream<A>,

Create a 𝒟 STREAM decryptor object from the given AEAD primitive.

pub fn from_stream_primitive(stream: S) -> Self

Create a 𝒟 STREAM decryptor object from the given STREAM primitive.

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

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

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

Use the underlying AEAD to decrypt the last AEAD message in this STREAM in-place, consuming the 𝒟 STREAM decryptor object in order to prevent further use.
