Module exonum::crypto

Cryptography related types and functions.

Sodium library is used under the hood through sodiumoxide rust bindings.

Reexports

pub use encoding::serialize::HexValue;

Structs

Hash	SHA256 hash.
HashStream	This structure provides a possibility to calculate hash for a stream of data
PublicKey	Public key used for verifying signatures.
SecretKey	Secret key used for signing.
Seed	Seed that can be used for keypair generation.
SignStream	This structure provides a possibility to create signature for a stream of data
Signature	Signature.

Enums

FromHexError

Constants

HASH_SIZE	Number of bytes in a Digest.
PUBLIC_KEY_LENGTH	Number of bytes in a PublicKey.
SECRET_KEY_LENGTH	Number of bytes in a SecretKey.
SEED_LENGTH	Number of bytes in a Seed.
SIGNATURE_LENGTH	Number of bytes in a Signature.

Functions

gen_keypair	Randomly generates a secret key and a corresponding public key.
gen_keypair_from_seed	Computes a secret key and a corresponding public key from a Seed.
hash	Calculates SHA256 hash of bytes slice.
init	Initializes the sodium library and chooses faster versions of the primitives if possible.
sign	Signs slice of bytes using the signer's secret key. Returns the resulting Signature.
verify	Verifies that data is signed with a secret key corresponding to the given public key.
