Variants

None = 0

No transform — submessage unsigned.

Aes128Gmac = 1

AES-128-GMAC (authentication only, no encrypt).

Aes128Gcm = 2

AES-128-GCM (Authentication + Encrypt).

Aes256Gmac = 3

AES-256-GMAC.

Aes256Gcm = 4

AES-256-GCM.

Implementations

impl CryptoTransformKind

pub const fn to_be_bytes(self) -> [u8; 4]

Wire-Bytes (4 BE).

pub fn from_be_bytes(bytes: [u8; 4]) -> Result<Self, &'static str>

Decode from 4 BE bytes.

Errors

A static string if the value is not in 0..=4.

pub const fn encrypts(self) -> bool

true if the transform does encryption (otherwise auth only).

pub const fn tag_size(self) -> usize

Spec §10.5.2.1 — Authentication-Tag-Length. Alle GCM/GMAC-Varianten verwenden 16 Byte Tag.

pub const fn key_size(self) -> usize

Key-Material-Size (Bytes) je Algorithmus.

Trait Implementations

impl Clone for CryptoTransformKind

fn clone(&self) -> CryptoTransformKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CryptoTransformKind

impl Debug for CryptoTransformKind

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

Formats the value using the given formatter.

impl Eq for CryptoTransformKind

impl Hash for CryptoTransformKind

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for CryptoTransformKind

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
