Module sodiumoxide::crypto::sign::ed25519 [−] [src]

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.
