Module sodiumoxide::crypto::kx::x25519blake2b[−][src]

Expand description

x25519blake2b is the current default key exchange scheme of libsodium.

Structs

PublicKey	`PublicKey` for key exchanges.
SecretKey	`SecretKey` for key exchanges.
Seed	`Seed` that can be used for keypair generation
SessionKey	`SessionKey` is returned by `client_session_keys` and `server_session_keys` and is the exchanged secret between the client and server.

PUBLICKEYBYTES	Number of bytes in a `PublicKey`.
SECRETKEYBYTES	Number of bytes in a `SecretKey`.
SEEDBYTES	Number of bytes in a `Seed`.
SESSIONKEYBYTES	Number of bytes in a `SessionKey`.

client_session_keys	`client_session_keys()` computes a pair of shared keys (rx and tx) using the client’s public key `client_pk`, the client’s secret key `client_sk` and the server’s public key `server_pk`. If the server’s public key is acceptable, it returns the two shared keys, the first for `rx` and the second for `tx`. Otherwise, it returns `None`.
gen_keypair	`gen_keypair()` randomly generates a secret key and a corresponding public key.
keypair_from_seed	`keypair_from_seed()` computes a secret key and a corresponding public key from a `Seed`.
server_session_keys	`server_session_keys()` computes a pair of shared keys (rx and tx) using the server’s public key `server_pk`, the server’s secret key `server_sk` and the client’s public key `client_pk`. If the client’s public key is acceptable, it returns the two shared keys, the first for `rx` and the second for `tx`. Otherwise, it returns `None`.
