使用nodejs實現ed25519的公鑰加密和私鑰解密

主要使用了 ed25519 庫

加解密和驗證代碼

// Common.js and ECMAScript Modules (ESM)
import * as ed from '@noble/ed25519';
// If you're using single file, use global variable instead: `window.nobleEd25519`

const verifyEd = async function (prikey, pubkey) {
    console.log("你輸入的私鑰是：" + prikey)
    console.log("環境變量中的公鑰是：" + pubkey)

    // ====================
    // 新私鑰開始
    // ====================
    // const newPrivateKey = ed.utils.randomPrivateKey();
    // const privateKeyStr = Buffer.from(newPrivateKey).toString('base64');
    // console.log("new privateKey=>", privateKeyStr)
    // ====================
    // 新私鑰結束
    // ====================
  
    const privateKeyStr = prikey

    const privateKey = Buffer.from(privateKeyStr, 'base64');
    // console.log("parsed privateKey=>", privateKey)

    // ====================
    // 新公鑰開始
    // ====================
    // const newPublicKey = await ed.getPublicKey(privateKey);
    // const publicKeyStr = Buffer.from(newPublicKey).toString('base64');
    // console.log("new publicKey=>", publicKeyStr)
    // ====================
    // 新公鑰結束
    // ====================
  
    const publicKeyStr = pubkey

    const publicKey = Buffer.from(publicKeyStr, 'base64');
    // console.log("parsed publicKey=>", publicKey)

    try {
        const valiPass = "123456";
        const message = Uint8Array.from(valiPass, x => x.charCodeAt(0))
        // const messageStr = Buffer.from(message).toString('base64');
        // console.log("校驗密碼：", valiPass)

        const signature = await ed.sign(message, privateKey);
        const isValid = await ed.verify(signature, message, publicKey);
        // console.log("驗證結果：", isValid ? "有效" : "無效")
        return isValid;
    } catch (e) {
        console.warn("校驗失敗，請檢查密碼", e)
        return false;
    }
}

const privateKeyStr = "prikey";
const publicKeyStr = "pubkey"
const valiResult = verifyEd(privateKeyStr, publicKeyStr)
valiResult.then(function(item){
    console.log("item=>", item)
})
