axios-sm-crypto

Axios wrapper for encrypting request parameters with SM4 and SM2, and decrypting response data from backend format.

Features

• Encrypts all request payload into a single encData field
• Supports SM4 symmetric encryption with SM2 public-key encryption of the SM4 key
• Automatically decrypts backend responses with code === 200
• Throws on code !== 200

Usage

import { createSMCryptoAxios } from 'axios-sm-crypto';

const client = createSMCryptoAxios({
  sm2PublicKey: '04...',
  sm2PrivateKey: '...'
});

const response = await client.post('/api/example', { foo: 'bar' });
console.log(response.data);

Request format

The request body will be rewritten as:

{
  "encData": "..."
}

Response format

Expects backend response like:

{
  "code": 200,
  "data": "xxxxx",
  "msg": ""
}

If code is 200, the package decrypts data and returns parsed JSON.
