Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

wxmp-rsa

1、简介

前端rsa加解密工具。

  • 基于jsencrypt修改扩展功能。
  • 兼容小程序环境,压缩后60kb左右的大小,节省小程序空间。
  • 支持超长文本加解密。
  • 支持中文字符的加解密。

2、安装

npm i wxmp-rsa -S

3、使用方式

(小程序使用之前需先使用开发者工具构建npm

// 导入包
import WxmpRsa from 'wxmp-rsa'

// 实例化rsa
const rsa = new WxmpRsa()

// 定义待加密的字符串
const str = '{"name":"neo"}'
// 定义公钥
const publicKey = `
  -----BEGIN PUBLIC KEY-----
  MIGeMA0GCSqGSIb3DQEBAQUAA4GMADCBiAKBgFnWSUwsmGawhMJ30z6y5li2jcf1

  iDBzUMqW3Kgehk2TAgMBAAE=
  -----END PUBLIC KEY-----
`
// 设置公钥
rsa.setPublicKey(publicKey)
// 加密
const cryptStr = rsa.encryptLong(str)
console.log('加密后的结果:', cryptStr)

// 定义私钥
const privateKey = `
-----BEGIN RSA PRIVATE KEY-----

// 设置私钥
rsa.setPrivateKey(privateKey)
// 解密
const originalStr = rsa.decryptLong(cryptStr)
console.log('解密后的原始数据:', originalStr)

其他api参考jsencrypt插件

4、注意事项

  • 填空方式默认pkcs1,目前暂不支持其它填空方式。

5、更新提示

  • 之前偶现的加密异常的问题已于v2.0.0+版本中修复。
  • 之前偶现的解密后部分中文乱码的问题已于v2.1.0+版本中修复。

6、测试对比

推荐两个第三方rsa工具,仅供参考。

  • 在线生成rsa公私钥:http://travistidwell.com/jsencrypt/demo/ (推荐1024长度的密钥)
  • 在线rsa加解密:http://www.toolzl.com/tools/testrsa.html (117超长加密,128超长解密)
