Functions

func GenerateKey

func GenerateKey(t testing.TB, rand io.Reader) (ed25519.PublicKey, ed25519.PrivateKey)

GenerateKey generates a public/private key pair using entropy from rand. If rand is nil, crypto/rand.Reader will be used.

The output of this function is deterministic, and equivalent to reading [SeedSize] bytes from rand, and passing them to [NewKeyFromSeed].

func VerifyWithOptions

func VerifyWithOptions(t testing.TB, publicKey ed25519.PublicKey, message, sig []byte, opts *ed25519.Options)

VerifyWithOptions reports whether sig is a valid signature of message by publicKey. A valid signature is indicated by returning a nil error. It will panic if len(publicKey) is not [PublicKeySize].

If opts.Hash is crypto.SHA512, the pre-hashed variant Ed25519ph is used and message is expected to be a SHA-512 hash, otherwise opts.Hash must be crypto.Hash(0) and the message must not be hashed, as Ed25519 performs two passes over messages to be signed.

The inputs are not considered confidential, and may leak through timing side channels, or if an attacker has control of part of the inputs.
