Struct proj_crypto::symmetric::Digest

pub struct Digest {
    pub digest: Digest,
}

A wrapper around sha256::Digest so that we can implement Drop on it to clean up the memory when it goes out of scope. This is necessary because often our shared secret keys are sha256 digests.

Fields

digest: Digest

The encapsulated sha256::Digest

Methods

impl Digest

fn as_slice(&self) -> [u8; 32]

returns the actual data of the digest (from inside the sha256::Digest)

Trait Implementations

impl Debug for Digest

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl PartialEq for Digest

fn eq(&self, __arg_0: &Digest) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &Digest) -> bool

This method tests for !=.

impl Eq for Digest

impl Clone for Digest

Used in hash_n_times. Unfortunately we can't derive Clone on types with destructors.

fn clone(&self) -> Digest

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Drop for Digest

fn drop(&mut self)

We are using sha256 digests as keys so we need to be careful with them. This function zeroes out the memory when it goes out of scope
