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.
const ( // PublicKeySize is the size, in bytes, of public keys as used in this package. PublicKeySize = 32 // PrivateKeySize is the size, in bytes, of private keys as used in this package. PrivateKeySize = 64 // SignatureSize is the size, in bytes, of signatures generated and verified by this package. SignatureSize = 64 // SeedSize is the size, in bytes, of private key seeds. These are the private key representations used by RFC 8032. SeedSize = 32 )

func GenerateKey ¶
GenerateKey generates a public/private key pair using entropy from rand. If rand is nil, crypto/rand.Reader will be used.
Sign signs the message with privateKey and returns a signature. It will panic if len(privateKey) is not PrivateKeySize.
type PrivateKey ¶
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.
