Jsencrypt框架
NPM Jsencrypt
1). npm安装
npm i jsencrypt
2). 导入
import 'jsencrypt';
3). 使用Git控制台创建私钥
# 创建
openssl genrsa -out rsa_1024_priv.pem 1024
# 查看私钥
cat rsa_1024_priv.pem
4). 使用Git控制台创建公钥
# 创建
openssl rsa -pubout -in rsa_1024_priv.pem -out rsa_1024_pub.pem
# 查看
cat rsa_1024_pub.pem
5). JS代码加密
let encrypt = new JSEncrypt();
encrypt.setPublicKey(PUB_KEY);
let encrypted = encrypt.encrypt('要加密的数据');
6). JS代码解密
let decrypt = new JSEncrypt();
decrypt.setPrivateKey(PRIV_KEY);
let decrypted = decrypt.decrypt('公钥加密后的数据');
