juneandgreen / sm-crypto Goto Github PK

你好：
请问一下webpack babel-polyfill 打包后ios10 （含ios10）以下系统不能使用，是我什么地方配置有误么？

用sm3计算100kb的内容差不多要1秒多，这个怎么优化？

现在看说明公钥和私钥是通过generateKeyPairHex生成的，有办法从pem文件或者p12之类的文件中读取到吗？

这个我不知道是加密导致的，还是我base64或者buffer等转换中导致。pdf加密，然后以表单上传到后端，下载，解密，生成pdf.
解密下载后的pdf可以打开，但是会提醒我修改了，用ultraEdit查看，最后一行EOF消失了。

这个issue可以打个question标签

doDecrypt似乎期待解码出来的是utf8的数据，如果明文是二进制的，会报错 Malformed UTF-8 data。
有办法开选项返回个Buffer、Uint8Array之类的吗，还是我应该直接改代码？

`let sigValueHex6 = sm2.doSignature("这是加密123456", privateKeyWeb, {
hash: true,
publicKeyWeb,
userId: '1234567812345678',
})
console.log(sigValueHex6);

let verifyResult6 = sm2.doVerifySignature("这是加密123456", sigValueHex6, publicKeyWeb, {
hash: true,
userId: '1234567812345678',
})

console.log(verifyResult6);`

错误如下 ：

这个问题很懵啊 所有的签名都能过去 但就是 验签 过不了 都会报** Cannot read property 'multiply' of null**

var sm2 = require('sm-crypto').sm2;
var sm3 = require('sm-crypto').sm3;
var sm4 = require('sm-crypto').sm4;
var assert = require('assert');

var plainMsg = 'hello world!';
var keypair = sm2.generateKeyPairHex();
console.log('keypair:' + keypair);

var i = 0
for (;;) {
i++;
if (i == 1000) {
i = 0;
}
var encryptData = sm2.doEncrypt(plainMsg, keypair.publicKey);
console.log('encrypt result:' + encryptData);
var decryptData = sm2.doDecrypt(encryptData, keypair.privateKey);
console.log('decrypt result:' + decryptData);
assert.equal(plainMsg == decryptData, true, 'error');

// var hashResult = sm3(plainMsg);
// console.log('sm3 hash:' + hashResult);

}

createPoint(x, y) {
let publicKey = '04' + x + y;
let point = _.getGlobalCurve().decodePointHex(publicKey);
return point;
}

SM2自己签名验签应该没啥问题，但是和别的语言是不通的

目前很多后端语言的SM4算法都已支持CBC模式, 比如: java的bouncycastle
期待作者支持一下SM4的CBC模式加解密

通过npm install @types/sm-crypto --save
安装成功，文件中也成功import，但是项目启动的时候报错：
Module not found: Error: Can't resolve 'sm-crypto' in 'D:\idea workspace\XXX\src\app'

angular 2+和react 项目都一样。

后端我用的bouncycastle，有时候生成的密钥能解开，有时候就解不开。

私钥：f4e08d945183fc9fa6425561e4799efa8facfe0b715cb93c2db8a8142aad6f24

调用方法：sm2.doSignature(待签名字符串,私钥)

结果：

发现一个现象, 前端用sm4加密, 原文包含emoji表情,以字符串形式传入, 后端解密发现emoji表情信息为乱码, 其余内容正常
前端自己加密, 自己解密, emoji正常;
后端对相同原文自己加密自己解密, emoji正常;
不进行加解密, emoji正常;

调试了一下发现, 如果原文入参转成数组, 比如 Buffer.from("😃"), 后端可以正常处理,
对后端包含emoji表情的密文, 解密后以数组输出, 再用Buffer.from("解密后的数组").toString(), 也可以正常显示了

感觉 utf8ToArray()以及arrayToUtf8()这两个函数对于emoji的处理需要优化支持一下
非前端开发, 能力有限, 只是找到了一个暂时解决的办法.

sm-crypto:0.3.6
后端采用java 公钥进行sm2加密，前端使用私钥进行解密。
前端解密时，计算出c3与checkC3校验时因字母大小写，导致验证失败。无法解密。
前端js加解密无此问题。
应加上字符串转为小写，判断是否一致。
104行
if (checkC3 === c3) { #此处修改为 if (checkC3.toLowerCase() === c3.toLowerCase() ) {
return output === 'array' ? msg : _.arrayToUtf8(msg)
} else {
return output === 'array' ? [] : ''
}

ec.js 源码引用到工程使用报错，将88行代码修改为 this.z = z === undefined ? BigInteger.ONE : z 后即可正常使用。

前端用Java后端传递的16进制公钥正常加解密，后端拿到前端给的密文无法解密。
但是用https://github.com/Saberization/SM2所生成的密文，后端可以正常解密。但是没有前端解密的方法。
密文是 16进制格式

sm2 前端去掉 04 后端加上 04 可以相互加解密，sm3 加密结果也是一致的。但是进行 sm4 加解密时候就出现没办法解密的问题，前端传给后端的代码后端解密不了，前端解后端的加密最后也输出的空......最后又找了一个 gm-crypto 解密的。请问这是什么原因啊 QAQ

sm4加密的时候如果需要加密的串太短且当padding为none时不进入加密循环 while (restLen >= BLOCK)，使得outArray为空，加密出来为空

建议webpack中的 libraryTarget: 'window',改成 umd
这样支持多种前端的模块使用场景

2222

function doSignature(msg, privateKey, { pointPool, der, hash, publicKey } = {}) {
let hashHex = typeof msg === 'string' ? _.parseUtf8StringToHex(msg) : _.parseArrayBufferToHex(msg);

if (hash) {
    // sm3杂凑
    let publicKey = publicKey || getPublicKeyFromPrivateKey(privateKey);
    hashHex = doSm3Hash(hashHex, publicKey);
}

修改为：

function doSignature(msg, privateKey, { pointPool, der, hash, publicKey } = {}) {
let hashHex = typeof msg === 'string' ? _.parseUtf8StringToHex(msg) : _.parseArrayBufferToHex(msg);

if (hash) {
    // sm3杂凑
    let pubKey= publicKey || getPublicKeyFromPrivateKey(privateKey);
    hashHex = doSm3Hash(hashHex, pubKey);
}

dist 中SM2随机出错，加密的数据 别的加密机或解密卡不能解密（自己加自己解没有问题，自己加的数据送到加密机不能解密 出错率 10%左右）以下抓取了一条出错数据：

我再前端纯html 脚本引用dist目录文件中sm2.js 文件 但是我再页面上无法引用其方法 不知道该怎么去引用 还望指引感谢！


目前 我以上的方式不太行
麻烦 作者帮忙 指引指引

ie不兼容

实际开发中遇到个问题，想请教下大佬们：

Go和Java均能解密出原文，但是用sm-crypto解密后结果是空的。。

有实现基于sm2的秘钥交换算法吗？

最近做项目遇到一个问题，我是用硬件里面的sm2加密（解密），使用sm-crypto解密（解密），发现大多数情况下都能成功，但是也存在不成功的时候。但是只使用硬件加密解密都能成功（测试1000次），使用sm-crypto加密解密也能成功（测试1000次），但是用交互使用的时候就存在不能解密的可能。请教一下这个问题是怎么回事？

这边测试，数据为200k左右时，sm.js返回的时间需要7s左右

测试发现 key 不是 16 位的长度直接会无法加解密, 待解加密字符串低于16位也无法加解密，大于16位仅加密16 位

测试代码：

const sm4key = [0x01, 0x23, 0x45, 0x67, 0x89, 0xab, 0xcd, 0xef, 0xfe, 0xdc, 0xba, 0x98, 0x76, 0x54, 0x32, 0x10]
// const sm4OriginData = [0x01, 0x23, 0x45, 0x67, 0x89, 0xab, 0xcd, 0xef, 0xfe, 0xdc, 0xba, 0x98, 0x76, 0x54, 0x32, 0x10]
const sm4OriginData = 'abcdefghijklmnopqrstuvwxyz'.split('').map(x => x.charCodeAt(0))
let sm4EncData = sm4.encrypt(sm4OriginData, sm4key)
console.log(sm4EncData)

let sm4DecData = sm4.decrypt(sm4EncData, sm4key)
console.log(sm4DecData.map(x => String.fromCharCode(x)).join(''))

output:

[
    5,  96, 145,
   84, 199, 170,
   36, 101, 198,
  106, 212,  61,
    8, 117, 167,

能给个demo吗，比如我想加密字符串"test"，要怎么做？谢谢

用 bouncycastle 实现的加解密（SM2/SM4-cbc）和本项目实现的加解密不兼容，互相无法解密另一方加密的内容。
目前的 SM4 加解密模式是 ecb 模式，实际上很多其他语言都是用cbc 模式来做…希望能支持cbc模式

如题，希望获取33位的压缩公钥，请问是否有办法提供

#1 因为我是直接引入网页使用，所以被这个问题折腾了好几天，既然dist目录提交到git了，还是更新一下吧:joy:

能实现下sm2的密钥交换算法吗？请求参考。

let sm2 = require('sm-crypto').sm2是会报错C1C2C3 is not defined

这里SM2是通过generateKeyPairHex()方法获取的公私钥，现需要使用别的语言生成的pem格式的公私钥，如何读取啊
