Trait Signer 

Source 
pub trait Signer {
    type Error;

    // Required methods
    fn platform(&self) -> Platform;
    fn sign(&self, client_data_hash: &[u8; 32]) -> Result<Vec<u8>, Self::Error>;
}
Expand description

Signs with an attested device key.

Hardware signers block, so call sign_request off any async executor.

Required Associated Types§

Source

type Error

The signer’s failure.

Required Methods§

Source

fn platform(&self) -> Platform

The platform whose signature encoding Signer::sign produces.

Source

fn sign(&self, client_data_hash: &[u8; 32]) -> Result<Vec<u8>, Self::Error>

Signs client_data_hash, the SHA-256 of the signature base, and returns the platform encoding: DER-encoded ECDSA on Android, a CBOR App Attest assertion on iOS.

§Errors

Returns the signer’s error when the key cannot sign.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
