Struct oasis_core_runtime::common::crypto::mrae::deoxysii::DeoxysII

#[repr(align(16))]
pub struct DeoxysII { /* private fields */ }

Deoxys-II-256-128 state.

We don’t store the key itself, but only components derived from the key. These components are automatically erased after the structure is dropped.

Implementations

impl DeoxysII

pub fn new(key: &[u8; 32]) -> DeoxysII

Creates a new instance using the provided key.

pub fn seal( &self, nonce: &[u8; 15], plaintext: impl AsRef<[u8]>, additional_data: impl AsRef<[u8]>, ) -> Vec<u8>

Encrypts and authenticates plaintext, authenticates the additional data and returns the result.

pub fn seal_into( &self, nonce: &[u8; 15], plaintext: &[u8], additional_data: &[u8], ciphertext_with_tag: &mut [u8], ) -> Result<usize, EncryptionError>

Like DeoxysII::seal but seals into ciphertext_with_tag, returning the number of bytes written.

pub fn open( &self, nonce: &[u8; 15], ciphertext_with_tag: impl AsMut<[u8]>, additional_data: impl AsRef<[u8]>, ) -> Result<Vec<u8>, DecryptionError>

Decrypts and authenticates ciphertext, authenticates the additional data and, if successful, returns the resulting plaintext. If the tag verification fails, an error is returned and the intermediary plaintext is securely erased from memory.

pub fn open_into( &self, nonce: &[u8; 15], ciphertext_with_tag: &mut [u8], additional_data: &[u8], plaintext: &mut [u8], ) -> Result<usize, DecryptionError>

Like DeoxysII::open but writes the plaintext into plaintext if successful, returning the number of bytes written.

Trait Implementations

impl Zeroize for DeoxysII

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.
