Module ring::aead [−][src]
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 [email protected] 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 |
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. |
