ed25519 signature

[0xJackJun]

ed25519_sign_verify_test Using @noble/ed25519(node.js) can't pass this test, but using crypto/ed25519 can pass the test.

=====================example code======================= package main

import ( "crypto/ed25519" "encoding/hex" "fmt" )

func sign(msg string) { var pub []byte var pri []byte var err error if pub, pri, err = ed25519.GenerateKey(nil); err != nil { err = fmt.Errorf("ed25519.GenerateKey failed", err.Error()) return } msgByte := []byte(msg) sig := ed25519.Sign(pri, msgByte) verify := ed25519.Verify(pub, msgByte, sig)

fmt.Println("pub:", pub)
fmt.Println("pri:", pri)
fmt.Println("msg:", msg)
fmt.Println("sig:", sig)
fmt.Println("verify:", verify)
pub_hex := hex.EncodeToString(pub)
fmt.Println("pub_hex: ", pub_hex)
sig_hex := hex.EncodeToString(sig)
fmt.Println("sig_hex: ", sig_hex)

}

func main() { var msg = "test" sign(msg) }

maybe you should let strings to bytes transfer； below is my tset typescript script

import dotenv from "dotenv";
dotenv.config();

import { AptosAccount,  AptosAccountObject} from "aptos";

const aptosAccountObject: AptosAccountObject = {
    address: "0x978c213990c4833df71548df7ce49d54c759d6b6d932de22b24d56060b7af2aa",
    privateKeyHex:
      // eslint-disable-next-line max-len
      "0xc5338cd251c22daa8c9c9cc94f498cc8a5c7e1d2e75287a5dda91096fe64efa5de19e5d1880cac87d57484ce9ed2e84cf0f9599f12e7cc3a52e4e7657a763f2c",
    publicKeyHex: "0xde19e5d1880cac87d57484ce9ed2e84cf0f9599f12e7cc3a52e4e7657a763f2c",
  };

(async () => {
  const alice = AptosAccount.fromAptosAccountObject(aptosAccountObject);

  // Print out account addresses.
  console.log("=== Addresses ===");
  console.log(`Alice: ${alice.address()}`);

  const msg = "2105.nonce_geek";

  const textEncoder = new TextEncoder();
  let str_bytes = textEncoder.encode(msg);

  console.log("Alice pubkey:", alice.pubKey());

  let signature = alice.signBuffer(str_bytes);
  console.log("signature:", signature);

})();

signBuffer function in aptos-core project ecosystem/typescript/sdk/src/aptos_account.ts ; implementation is below; it use nacl library

  /**
   * Signs specified `buffer` with account's private key
   * @param buffer A buffer to sign
   * @returns A signature HexString
   */
  signBuffer(buffer: Uint8Array): HexString {
    const signature = nacl.sign(buffer, this.signingKey.secretKey);
    return HexString.fromUint8Array(signature.slice(0, 64));
  }
