[][src]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.

Nonce

A nonce for a single AEAD opening or sealing operation.

OpeningKey

A key for authenticating and decrypting (“opening”) AEAD-protected data.

SealingKey

A key for encrypting and signing (“sealing”) data.

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.

Functions

open_in_place

Authenticates and decrypts (“opens”) data in place.

seal_in_place

Encrypts and signs (“seals”) data in place.
