Trait Implementations

impl<'a> Digest<'a, 32> for Hmac<'a>

fn set_client(&'a self, client: &'a dyn Client<32>)

Set the client instance which will receive hash_done(), add_data_done() and verification_done() callbacks.

impl<'a> DigestData<'a, 32> for Hmac<'a>

fn add_data( &self, data: SubSlice<'static, u8>, ) -> Result<(), (ErrorCode, SubSlice<'static, u8>)>

Add data to the input of the hash function/digest. Ok indicates all of the active bytes in data will be added. There is no guarantee the data has been added to the digest until the add_data_done() callback is called. On error the cause of the error is returned along with the SubSlice unchanged (it has the same range of active bytes as the call). Valid ErrorCode values are:

fn add_mut_data( &self, data: SubSliceMut<'static, u8>, ) -> Result<(), (ErrorCode, SubSliceMut<'static, u8>)>

Add data to the input of the hash function/digest. Ok indicates all of the active bytes in data will be added. There is no guarantee the data has been added to the digest until the add_mut_data_done() callback is called. On error the cause of the error is returned along with the SubSlice unchanged (it has the same range of active bytes as the call). Valid ErrorCode values are:

fn clear_data(&self)

Clear the keys and any other internal state. Any pending operations terminate and issue a callback with an ErrorCode::CANCEL. This call does not clear buffers passed through add_mut_data, those are up to the client clear.

fn set_data_client(&'a self, _client: &'a (dyn ClientData<32> + 'a))

Set the client instance which will handle the add_data_done and add_mut_data_done callbacks.

impl<'a> DigestHash<'a, 32> for Hmac<'a>

fn run( &'a self, digest: &'static mut [u8; 32], ) -> Result<(), (ErrorCode, &'static mut [u8; 32])>

Compute a digest of all of the data added with add_data and add_data_mut, storing the computed value in digest. The computed value is returned in a hash_done callback. On error the return value will contain a return code and the slice passed in digest. Valid ErrorCode values are:

fn set_hash_client(&'a self, _client: &'a (dyn ClientHash<32> + 'a))

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

impl<'a> DigestVerify<'a, 32> for Hmac<'a>

fn verify( &'a self, compare: &'static mut [u8; 32], ) -> Result<(), (ErrorCode, &'static mut [u8; 32])>

Compute a digest of all of the data added with add_data and add_data_mut then compare it with value in compare. The compare value is returned in a verification_done callback, along with a boolean indicating whether it matches the computed value. On error the return value will contain a return code and the slice passed in compare. Valid ErrorCode values are:

fn set_verify_client(&'a self, _client: &'a (dyn ClientVerify<32> + 'a))

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