Struct HashInstance 

pub struct HashInstance { /* private fields */ }

A hash instance.

Implementations

impl HashInstance

pub fn new(alg: TpmiAlgHash) -> Result<Self, Infallible>

Create a new hash instance for the specified algorithm.

Arguments:

• alg - The hash algorithm to create an instance for.

pub fn try_clone(&self) -> Result<Self, Infallible>

pub fn update<'a, DI: CryptoIoSlicesIter<'a>>( &mut self, data: DI, ) -> Result<(), CryptoError>

Append to the digested data.

Arguments:

• data - The data to digest.

pub fn finalize_into_reset( &mut self, digest: &mut [u8], ) -> Result<(), Infallible>

Produce a digest into a provided buffer and reset the hash instance.

Produce a digest into digest and reset the hash instance to the state it would have had right after Self::new().

Arguments:

• digest - Destination to write the produced digest to.

pub fn finalize_into(self, digest: &mut [u8]) -> Result<(), Infallible>

Produce the final digest into a provided buffer..

Arguments:

• digest - Destination to write the produced digest to.

pub fn finalize_reset(&mut self) -> Result<TpmtHa<'static>, CryptoError>

Produce a digest and reset the hash instance.

Allocate a buffer suitable for the instance’s digest length, produce a digest into it and reset the hash instance to the state it would have had right after Self::new().

pub fn finalize(self) -> Result<TpmtHa<'static>, CryptoError>

Produce the final digest.

Allocate a buffer suitable for the instance’s digest length and produce the final digest into it.

pub fn digest_len(&self) -> usize

Determine the instance’s associated hash algorithm’s digest length.
