Struct ZeroizingKeypair 

pub struct ZeroizingKeypair { /* private fields */ }

Zeroize-on-drop wrapper for snow::Keypair.

snow::Keypair has no Drop impl, so the private key persists in freed memory if not explicitly zeroized. This wrapper guarantees zeroization on drop, including during panics (unwind calls Drop).

All code that constructs or receives a snow::Keypair should use this wrapper instead. The private key is accessible via private() for passing to snow::Builder::local_private_key().

Implementations

impl ZeroizingKeypair

pub fn new(keypair: Keypair) -> Self

Wrap a snow::Keypair, taking ownership.

pub fn public(&self) -> &[u8]

Access the public key (32 bytes).

pub fn private(&self) -> &[u8]

Access the private key (32 bytes). Use only for snow::Builder calls.

pub fn as_inner(&self) -> &Keypair

Borrow the inner snow::Keypair for APIs that require &snow::Keypair.

pub fn into_inner(self) -> Keypair

Consume the wrapper and return the inner snow::Keypair.

The caller takes responsibility for zeroizing the private key. Use only when transferring ownership to an API that requires snow::Keypair (e.g., BusServer::bind).

Trait Implementations

impl Drop for ZeroizingKeypair

fn drop(&mut self)

Executes the destructor for this type.

impl From<Keypair> for ZeroizingKeypair

fn from(keypair: Keypair) -> Self

Converts to this type from the input type.
