Expand description

Sign a message.

This is a generic interface, and it is up to the implementation as to the signing algorithm being used.

  • HL: The length in bytes of the hash.
  • SL: The length in bytes of the signature.

Required Methods§

Source

fn set_sign_client(&self, client: &'a dyn ClientSign<HL, SL>)

Set the client instance which will receive the signing_done() callback.

Source

fn sign( &self, hash: &'static mut [u8; HL], signature: &'static mut [u8; SL], ) -> Result<(), (ErrorCode, &'static mut [u8; HL], &'static mut [u8; SL])>

Sign the given hash.

If this returns Ok(()), then the signing_done() callback will be called. If this returns Err(), no callback will be called.

The valid ErrorCodes that can occur are:

  • OFF: the underlying digest engine is powered down and cannot be used.
  • BUSY: there is an outstanding operation already in process, and the signing engine cannot accept another request.
