Does uniapp generate keys?

Uniapp is a cross-platform application development framework that can develop applications for multiple platforms such as iOS, Android and Web at the same time. In the development of applications, keys are often needed to perform data encryption and decryption, identity verification and other related operations. So, can keys be generated in Uniapp? Let’s introduce it below.

The Uniapp framework itself does not provide the function of generating keys, but it can be achieved using the uni-app plug-in and third-party libraries. Next, they will be introduced separately.

1. uni-app plug-in

There is a plug-in called uni-crypto-js in the Uni-app plug-in, which can implement encryption and decryption algorithms using JavaScript. The plug-in supports symmetric encryption algorithms, hash algorithms and asymmetric encryption algorithms. At the same time, it can also generate related content such as keys, private keys, and public keys.

Before using this plug-in, you need to install it first. You can execute the following command directly in the application root directory to install:

npm install --save uni-crypto-js

After the installation is complete, introduce the plug-in into the code:

import CryptoJS from 'uni-crypto-js'

Then you can use CryptoJS objects to perform related operations.

2. Third-party library

In addition to using plug-ins, we can also use third-party libraries to achieve the function of generating keys. It is recommended to use the jsencrypt.js library here. It is a JavaScript library for using RSA public key encryption on the front end. The library is capable of generating RSA key pairs and public keys, supporting both encryption and decryption operations.

Before using this library, you need to install it first. You can execute the following command directly in the application root directory to install:

npm install --save jsencrypt

After the installation is complete, introduce the library into the code:

import JSEncrypt from 'jsencrypt'

Then use the JSEncrypt object to generate the key, private key and public key. key.

const encrypt = new JSEncrypt({default_key_size: 2048})
const privateKey = encrypt.getPrivateKey()
const publicKey = encrypt.getPublicKey()

The above are the two ways to generate keys in Uniapp. By using uni-app plug-ins and third-party libraries, encryption, decryption, and key data protection can be quickly achieved. Of course, when using these libraries and plug-ins, you need to ensure the security of the code to prevent data from being stolen by malicious attackers.
