问题描述
这可能需要 https://www.npmjs.com/package/eccrypto 中的某种背景。我正在尝试解密从使用 ECIES 方案的 api 检索到的消息,但它一直告诉我公钥是“坏的”。
错误:
Uncaught (in promise) Error: Bad public key
at assert (genKey.js:33656)
at genKey.js:33830
at new Promise (<anonymous>)
at exports.derive (genKey.js:33828)
at Object.exports.decrypt (genKey.js:33886)
at window.decryptMes (genKey.js:26722)
at window.search (Login.js:86)
我很确定您在消息对象中传递的解密参数包含其中的公钥。如果我错了,那么它是从私钥参数派生的,但我不相信这是,因为私钥似乎没问题,并且在解密时从私钥派生公钥与 ECIES 解密的操作相反,加密是另一回事。
window.decryptMes = async function(data)
{
var skey = getSKey();
if (skey === null || undefined)
{
console.log('You do not have a key pair');
return;
}
console.log("skey is not null");
console.log(`data returned ${data}`); //data is returning undefined!
var decryptedMes = await eccrypto.decrypt(skey,data);
var deMes = decryptedMes.toString();
console.log(deMes);
return deMes;
}
window.getSKey = function()
{
console.log("getSKey flag: 0");
var skey = localStorage.getItem("skey");
const SKey = Buffer.from(skey,'hex');
//var skey = base642Array(SKey);
console.log("getSKey flag: 1");
console.log("getSKey flag: 2");
//console.log(skey);
return SKey;
}
这是消息对象在发送到 API 供以后检索之前加密的方式:
window.encryptMes = async function(data)
{
//for this you need to get the sender's public key to encrypt the message
console.log("encryptmes: began");
var pkey = genPKey();
if (pkey === null || undefined)
{
console.log('You do not have a key pair');
}
var encryptedMes = await eccrypto.encrypt(pkey,Buffer.from(data));
var enMes = encryptedMes.toString('hex');
//question Now becomes,WHY IS THIS RETURNING OBJECT OBJECT
console.log(`encryptedMes returned: ${encryptedMes}`); //Could be this since it is not stringified when it goes into celox network
console.log(`enMes returned: ${enMes}`);
console.log(`enMes completed successfully`);
return enMes;
}
window.genPKey = function()
{
console.log("getSKey flag: 0");
const skey = localStorage.getItem('skey');
const SKey = Buffer.from(skey,'hex');
console.log("getSKey flag: 1");
if(SKey != null || undefined)
{
console.log(SKey);
console.log("getSKey flag: 2");
const publicKey = eccrypto.getPublic(SKey);
const pkey = publicKey.toString('hex');
localStorage.setItem('pkey',pkey);
//encrypt(SKey.publicKey.toHex(),"fuck this is shitty");
console.log("getSKey flag: 3");
//localStorage.setItem("pkey",window.btoa(JSON.stringify(publicKey)));
return publicKey;
}
我不确定出了什么问题,因为我确实提供了带有有效私钥的解密消息功能,据我所知,我首先正确地加密了消息,这就是我最终传递给解密消息的内容功能。我做错了什么?任何帮助和关闭对我来说都非常有用。谢谢。
