github.com/lestrrat-go/dsig-circl-ed448 
Ed448 signing/verification support for github.com/lestrrat-go/dsig, powered by cloudflare/circl.
Why a separate module?
Go's standard library does not include Ed448 support. The only viable implementation comes from github.com/cloudflare/circl, which is a large dependency. Rather than forcing every dsig user to pull in circl, Ed448 support is provided as an opt-in companion module.
Synopsis
Import this package for its side effects to register Ed448 with dsig:
package ed448_test
import (
"fmt"
"github.com/cloudflare/circl/sign/ed448"
"github.com/lestrrat-go/dsig"
_ "github.com/lestrrat-go/dsig-circl-ed448"
)
func Example() {
// Generate an Ed448 key pair
pub, priv, err := ed448.GenerateKey(nil)
if err != nil {
fmt.Printf("failed to generate key: %s\n", err)
return
}
payload := []byte("Hello, Ed448!")
// Sign with Ed448 private key
signature, err := dsig.Sign(priv, "Ed448", payload, nil)
if err != nil {
fmt.Printf("failed to sign: %s\n", err)
return
}
// Verify with Ed448 public key
if err := dsig.Verify(pub, "Ed448", payload, signature); err != nil {
fmt.Printf("failed to verify: %s\n", err)
return
}
fmt.Println("signature verified")
// Output:
// signature verified
}

Overview ¶
Package ed448 provides Ed448 signing and verification support for the dsig library.
Ed448 is not included in the main dsig module because Go's standard library does not support Ed448, requiring the external github.com/cloudflare/circl module. To avoid adding this dependency for all users, Ed448 support is provided as a separate module.
To enable Ed448 support, import this package for its side effects:
import _ "github.com/lestrrat-go/dsig-circl-ed448"
This registers an "Ed448" algorithm with dsig. After importing, dsig.Sign and dsig.Verify can be used with the "Ed448" algorithm name.
Example ¶
package main
import (
"fmt"
"github.com/cloudflare/circl/sign/ed448"
"github.com/lestrrat-go/dsig"
_ "github.com/lestrrat-go/dsig-circl-ed448"
)
func main() {
// Generate an Ed448 key pair
pub, priv, err := ed448.GenerateKey(nil)
if err != nil {
fmt.Printf("failed to generate key: %s\n", err)
return
}
payload := []byte("Hello, Ed448!")
// Sign with Ed448 private key
signature, err := dsig.Sign(priv, "Ed448", payload, nil)
if err != nil {
fmt.Printf("failed to sign: %s\n", err)
return
}
// Verify with Ed448 public key
if err := dsig.Verify(pub, "Ed448", payload, signature); err != nil {
fmt.Printf("failed to verify: %s\n", err)
return
}
fmt.Println("signature verified")
}
Output: signature verified
