Module sodiumoxide::crypto::sign::ed25519

ed25519, a signature scheme specified in Ed25519. This function is conjectured to meet the standard notion of unforgeability for a public-key signature scheme under chosen-message attacks.

Structs

PublicKey

PublicKey for signatures

SecretKey

SecretKey for signatures

Seed

Seed that can be used for keypair generation

Signature

Detached signature

Constants

PUBLICKEYBYTES

Number of bytes in a PublicKey.

SECRETKEYBYTES

Number of bytes in a SecretKey.

SEEDBYTES

Number of bytes in a Seed.

SIGNATUREBYTES

Number of bytes in a Signature.

Functions

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.

sign

sign() signs a message m using the signer’s secret key sk. sign() returns the resulting signed message sm.

sign_detached

sign_detached() signs a message m using the signer’s secret key sk. sign_detached() returns the resulting signature sig.

verify

verify() verifies the signature in sm using the signer’s public key pk. verify() returns the message Ok(m). If the signature fails verification, verify() returns Err(()).

verify_detached

verify_detached() verifies the signature in sig against the message m and the signer’s public key pk. verify_detached() returns true if the signature is valid, false otherwise.
