Functions

func ExtractPublicKey

func ExtractPublicKey(priv ed25519.PrivateKey) ed25519.PublicKey

ExtractPublicKey extracts the PublicKey portion of priv.

func Sign

func Sign(priv ed25519.PrivateKey, hash crypto.Hash) []byte

Sign signs a hash with priv.

func Verify

func Verify(pub ed25519.PublicKey, hash crypto.Hash, sig []byte) bool

Verify reports whether sig is a valid signature of hash by pub.

func VerifyBatch

func VerifyBatch(keys []ed25519.PublicKey, hashes [][32]byte, sigs [][]byte) bool

VerifyBatch verifies a set of signatures. This provides a speedup of roughly 2x compared to verifying the signatures individually. However, if verification fails, the caller cannot determine which signatures were invalid without resorting to individual verification.

func VerifySingleKeyBatch

func VerifySingleKeyBatch(pub ed25519.PublicKey, hashes [][32]byte, sigs [][]byte) bool

VerifySingleKeyBatch verifies a set of signatures that were all produced by the same key. This provides a speedup of roughly 4x compared to verifying the signatures individually. However, if verification fails, the caller cannot determine which signatures were invalid without resorting to individual verification.
