前端js sm2实现加密简单代码举例

npm install sm-crypto # 或者 yarn add sm-crypto或者pnpm install sm-crypto

// 在需要加密的组件或者文件中引入
import smcrypto from 'sm-crypto'

const signIn = async () => {
  const userlogin = {
    username: formData.username,
    password: '04' + smcrypto.sm2.doEncrypt(formData.password, publicKey.value),
    code: code.value,
    captcha: formData.captcha,
    publicKey: publicKey.value
  }
 loginApi(userlogin)
    .then(async (res) => {
...})
}

这里是直接使用加密，也可以封装成函数

npm install sm-crypto --save

// utils.js

import smcrypto from 'sm-crypto';

    // SM2 加密
  export function  encrypt (plaintext, publicKey) {
        try {
            const cipherMode = 1; // 1 - C1C3C2，0 - C1C2C3
            const cipherText = smcrypto.sm2.doEncrypt(plaintext, publicKey, cipherMode);
            return cipherText;
        } catch (error) {
            console.error('SM2 encryption error:', error);
            return null;
        }
    }

import { encrypt } from '@/utils/smcrypto.js';

        // 获取加密私钥
        getPublicKey() {
            api.publicKey().then((res) => {
                this.param.rsaToken = res.data.rsaToken;
                this.rsaKey = res.data.rsaKey;
            });
        },

//登录请求参数

      let data = {
                        password: this.param.password,
                        username: this.param.username,
                        captchaCode: this.param.captchaCode,
                        captchaId: this.param.captchaId,
                        rsaToken: this.param.rsaToken,
                        // authCode: this.param.authCode,
                        checked: this.param.checked
                    };
                    data.password = encrypt(this.param.password, this.rsaKey);
//发起登录请求
//...
