利用jsencrypt 做非对称加密

1、生成 private key

openssl genrsa -out rsa_1024_priv.pem 1024

2、生成public key

openssl rsa -pubout -in rsa_1024_priv.pem -out rsa_1024_pub.pem

3、根据public key对数据加密

let encrypt = new JSEncrypt();
encrypt.setPublicKey(__YOU_CREATE_PUBLIC_KEY__);
let encrypted = encrypt.encrypt(__YOU_ENCRYPT_DATA__);

4、根据private key对加密数据解密

let decrypt = new JSEncrypt();
decrypt.setPrivateKey(__YOU_CREATE_PRIVATE_KEY___);
let uncrypted = decrypt.decrypt(__YOU_ENCRYPTED_DATA__);
