Involved Source Files d➜ ed25519_go113.go Package ed25519 implements the Ed25519 signature algorithm. See https://ed25519.cr.yp.to/. These functions are also compatible with the “Ed25519” function defined in RFC 8032. However, unlike RFC 8032's formulation, this package's private key representation includes a public key suffix to make multiple signing operations with the same key more efficient. This package refers to the RFC 8032 private key as the “seed”. Beginning with Go 1.13, the functionality of this package was moved to the standard library as crypto/ed25519. This package only acts as a compatibility wrapper.

Package-Level Type Names (total 2, both are exported)

/* sort exporteds by: alphabet | popularity */

type PrivateKey = ed25519.PrivateKey ([]T) PrivateKey is the type of Ed25519 private keys. It implements crypto.Signer. This type is an alias for crypto/ed25519's PrivateKey type. See the crypto/ed25519 package for the methods on this type.

type PublicKey = ed25519.PublicKey ([]T) PublicKey is the type of Ed25519 public keys. This type is an alias for crypto/ed25519's PublicKey type. See the crypto/ed25519 package for the methods on this type.

Package-Level Functions (total 4, all are exported)

func GenerateKey(rand io.Reader) (PublicKey, PrivateKey, error) GenerateKey generates a public/private key pair using entropy from rand. If rand is nil, crypto/rand.Reader will be used.

func NewKeyFromSeed(seed []byte) PrivateKey NewKeyFromSeed calculates a private key from a seed. It will panic if len(seed) is not SeedSize. This function is provided for interoperability with RFC 8032. RFC 8032's private keys correspond to seeds in this package.

func Sign(privateKey PrivateKey, message []byte) []byte Sign signs the message with privateKey and returns a signature. It will panic if len(privateKey) is not PrivateKeySize.

func Verify(publicKey PublicKey, message, sig []byte) bool Verify reports whether sig is a valid signature of message by publicKey. It will panic if len(publicKey) is not PublicKeySize.

Package-Level Constants (total 4, all are exported)

const PrivateKeySize = 64 PrivateKeySize is the size, in bytes, of private keys as used in this package.

const PublicKeySize = 32 PublicKeySize is the size, in bytes, of public keys as used in this package.

const SeedSize = 32 SeedSize is the size, in bytes, of private key seeds. These are the private key representations used by RFC 8032.

const SignatureSize = 64 SignatureSize is the size, in bytes, of signatures generated and verified by this package.
