Required Methods

fn init(key: &XSalsa20Key, nonce: &XSalsa20Nonce) -> Self

Return a properly initialized SimpleX secretbox.

Beware that SimpleX uses a non-standard initialization like this:

intermediate = hsalsa20(xsalsa20_key, [0u8; 16]); xsalsa20 = xsalsa20_init(intermediate, xsalsa20_nonce); poly1305_key = (first 32 bytes of xsalsa20 cipherstream);

fn encrypt_chunk(&mut self, chunk: impl AsRef<[u8]>, buf: impl AsMut<[u8]>)

Write a ciphertext into a buf. Update poly1305 but do not authenticate the chunk, the auth tag must be put only at the end of the whole message.

fn decrypt_chunk(&mut self, chunk: impl AsRef<[u8]>, buf: impl AsMut<[u8]>)

Write a plaintext into a buf. chunk is always pure ciphertext, simploxide utilities guarantee that auth_tag won’t appear in the input chunk.

fn auth_tag(&mut self) -> Poly1305Tag

fn verify_tag(&mut self, tag_to_verify: &Poly1305Tag) -> bool

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
