Struct wolf_crypto::mac::poly1305::StreamPoly1305

pub struct StreamPoly1305 { /* private fields */ }

Represents an ongoing streaming MAC computation, allowing incremental updates.

Example

use wolf_crypto::{mac::{Poly1305, poly1305::Key}, aead::Tag};

let key: Key = [0u8; 32].into();
let mut stream = Poly1305::new(key.as_ref())
    .update(b"chunk1")?
    .update(b"chunk2")?
    .update(b"chunk3")?;

let tag = stream.finalize()?;

Implementations

impl StreamPoly1305

pub fn update(self, input: &[u8]) -> Result<Self, Self>

Updates the streaming MAC computation with additional input.

Arguments

• input - A byte slice representing the additional data to include.

Returns

A Result<&mut Self, Unspecified> containing a mutable reference to StreamPoly1305 for chaining or an Unspecified error on failure.

Example

use wolf_crypto::{mac::{Poly1305, poly1305::Key}, aead::Tag};

let key: Key = [0u8; 32].into();

let tag = Poly1305::new(key.as_ref())
    .update(b"chunk1")?
    .update(b"chunk2")?
    .update(b"chunk3")?
    .finalize()?;

pub fn finalize(self) -> Result<Tag, Unspecified>

Finalizes the streaming MAC computation and returns the resulting Tag.

Returns

A Result<Tag, Unspecified> containing the computed Tag on success or an Unspecified error on failure.

Example

use wolf_crypto::{mac::{Poly1305, poly1305::Key}, aead::Tag};

let key: Key = [0u8; 32].into();

let tag = Poly1305::new(key.as_ref())
    .update(b"chunk1")?
    .update(b"chunk2")?
    .update(b"chunk3")?
    .finalize()?;
