[−][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. |
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. |
