代码

使用了jsencrypt这个库 jsencrypt 其实非常简单

前端

$('#submit').click(function() {
// Encrypt with the public key...
var encrypt = new JSEncrypt();
encrypt.setPublicKey(public_key);
document.getElementById("passwd").value = encrypt.encrypt($('#passwd').val());
 });

后端解密

    def decrypt_password(passwd):
        privkey = rsa.PrivateKey.load_pkcs1(app.config['RSA_PKEY'])
        try:
            data = rsa.decrypt(passwd, privkey)
            return data
        except:
            print("[DECRYPT] Password decrypt error.")
