Struct orion::hazardous::mac::poly1305::OneTimeKey

#[must_use]
pub struct OneTimeKey { /* fields omitted */ }

A type to represent the OneTimeKey that Poly1305 uses for authentication.

Errors:

An error will be returned if:

• slice is not 32 bytes.

Panics:

A panic will occur if:

• The OsRng fails to initialize or read from its source.

Security:

• Avoid using unprotected_as_bytes() whenever possible, as it breaks all protections that the type implements.

Methods

impl OneTimeKey

#[must_use]

pub fn from_slice(slice: &[u8]) -> Result<OneTimeKey, UnknownCryptoError>

Make an object from a given byte slice.

#[must_use]

pub fn unprotected_as_bytes(&self) -> &[u8]

Return the object as byte slice. Warning: Should not be used unless strictly needed. This breaks protections that the type implements.

#[must_use]

pub fn generate() -> OneTimeKey

Randomly generate using a CSPRNG. Not available in no_std context.

pub fn get_length(&self) -> usize

Return the length of the object.

Trait Implementations

impl Drop for OneTimeKey

fn drop(&mut self)

Executes the destructor for this type.

impl PartialEq<OneTimeKey> for OneTimeKey

fn eq(&self, other: &OneTimeKey) -> bool

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

#[must_use]

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl From<[u8; 32]> for OneTimeKey

fn from(bytes: [u8; 32]) -> OneTimeKey

Make an object from a byte array.

impl Debug for OneTimeKey

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

Formats the value using the given formatter.
