Module aead

Source
Expand description

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
A possibly valid 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 8439.

Traits§

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