RSA encryption and decryption is simple to use

The business scenario is very simple:

Enter the password at the front end, which is encrypted and transmitted to the background, and used after decryption.

The first step is to generate a key, see http://blog.csdn.net/gengxiaoming7/article/details/78505107

I only use the first two commands

openssl genrsa -out rsa_private.key 2048

openssl rsa -in rsa_private.key -pubout -out rsa_public.key

The front end should be encrypted with js, and used to

https://github.com/rzcoder/node-rsa

This is used in the webpack environment

https://github.com/ziyan/javascript-rsa

This is used in the general web, directly importing js files

 

Backend uses php

$prikeyid = openssl_get_privatekey($private_key);

openssl_private_decrypt(base64_decode($cipher_text), $decrypted, $prikeyid));

echo $decrypted;
