Authenticated Encryption with Associated Data (AEAD) Functions

The 0xFFFF AEAD ID is reserved for applications which only use the Export interface; see HPKE for more details.

Value	AEAD	Nk	Nn	Nt	Reference
0x0000	(reserved)	N/A	N/A	N/A	N/A
0x0001	AES-128-GCM	16	12	16	GCM
0x0002	AES-256-GCM	32	12	16	GCM
0x0003	ChaCha20Poly1305	32	12	16	RFC8439
0xFFFF	Export-only	N/A	N/A	N/A	RFCXXXX

The “HPKE AEAD Identifiers” registry lists identifiers for authenticated encryption with associated data (AEAD) algorithms defined for use with HPKE. These identifiers are two-byte values, so the maximum possible value is 0xFFFF = 65535.

Template:

• Value: The two-byte identifier for the algorithm
• AEAD: The name of the algorithm
• Nk: The length in bytes of a key for this algorithm
• Nn: The length in bytes of a nonce for this algorithm
• Nt: The length in bytes of an authentication tag for this algorithm
• Reference: Where this algorithm is defined

Trait Implementations

impl Clone for AEAD

fn clone(&self) -> AEAD

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AEAD

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

Formats the value using the given formatter.

impl PartialEq for AEAD

fn eq(&self, other: &AEAD) -> 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.
