Module ring::aead

Authenticated Encryption with Associated Data (AEAD).

See Authenticated encryption: relations among notions and analysis of the generic composition paradigm for an introduction to the concept of AEADs.

Modules

chacha20_poly1305_openssh	The chacha20-poly1305@openssh.com AEAD-ish construct.
quic	QUIC Header Protection.

Structs

Aad	The additionally authenticated data (AAD) for an opening or sealing operation. This data is authenticated but is not encrypted.
Algorithm	An AEAD Algorithm.
LessSafeKey	Immutable keys for use in situations where OpeningKey/SealingKey and NonceSequence cannot reasonably be used.
Nonce	A nonce for a single AEAD opening or sealing operation.
OpeningKey	An AEAD key for authenticating and decrypting ("opening"), bound to a nonce sequence.
SealingKey	An AEAD key for encrypting and signing ("sealing"), bound to a nonce sequence.
Tag	An authentication tag.
UnboundKey	An AEAD key without a designated role or nonce sequence.

Constants

MAX_TAG_LEN	The maximum length of a tag for the algorithms in this module.
NONCE_LEN	All the AEADs we support use 96-bit nonces.

Statics

AES_128_GCM	AES-128 in GCM mode with 128-bit tags and 96 bit nonces.
AES_256_GCM	AES-256 in GCM mode with 128-bit tags and 96 bit nonces.
CHACHA20_POLY1305	ChaCha20-Poly1305 as described in RFC 7539.

Traits

BoundKey	An AEAD key bound to a nonce sequence.
NonceSequence	A sequences of unique nonces.
