Invalidate JWT Token in NodeJS

放肆的年华 提交于 2019-12-11 03:04:17
问题 I followed this tutorial for using JWT token. The token expiry is set to only 5 minutes, but what if I wanted to invalidate the token after 1 minute of use? I want to be able to make an API call to /api/logout and that should delete my token. I'm using Express and Node. It seems like from what I could gather to do my option is to have a token db that stores the token. When I want to expire my token, I then expire/remove the token from the DB. I've also seen people casually say "remove" the

Paypal : invalid token only in DoExpressCheckoutPayment method

问题 I'm starting to work with PayPal and my first work is to debug it on our website. Actually when we go to the end of an order, it works fine but we get a stack in the logs : "Invalid token (#10410: Invalid Token)" . This happens when the doExpressCheckoutPayment is called and it seems like there's no token and no payerid so an error is thrown. All other information seem to be correctly filled. Here's the debug result calling doExpressCheckoutPayment : [DoExpressCheckoutPayment] => Array (

Create random, unique tokens upon account creation in Rails

谁说胖子不能爱 提交于 2019-12-11 02:57:16
问题 I have a Rails 4 app using Devise (the most recent) and am trying to create a random token for each user (like the ID, but longer, etc.) Using this answer I was able to come up with the follow code: # app/models/model_name.rb class ModelName < ActiveRecord::Base include Tokenable end # app/models/concerns/tokenable.rb module Tokenable extend ActiveSupport::Concern included do before_create :generate_token end protected def generate_token self.token = loop do random_token = SecureRandom

Token delegation using LOGON32_LOGON_NETWORK_CLEARTEXT

↘锁芯ラ 提交于 2019-12-11 02:35:36
问题 How safe is it to use LOGON32_LOGON_NETWORK_CLEARTEXT? We have the following scenario: Web server A is using Win32 LogonUser. Then it needs to invoke an asmx method on server B. If the used logon type is LOGON32_LOGON_INTERACTIVE it works well. However the customer rejects this because it requires interactive access. If we use LOGON32_LOGON_NETWORK this does not allow token delegation to the remote server and we get 401 (as expected, according to the MSDN). Attempting to use DuplicateToken to

Is an OAuth 2.0 token forever unique to the provider?

别来无恙 提交于 2019-12-11 02:26:39
问题 When an OAuth 2.0 provider issues a token, is that token value forever unique to the provider? Or is it possible that sometime in the future, presumably after the token expires, another token, potentially for a different user, could be issued with the same value? In searching I found much information about tokens expiring, but no details about if that token value could potentially be re-used in the future. 回答1: There's nothing in the core OAuth 2 spec that guarantees this. It is

问题 I want to preserve the special character in the token, meanwhile still tokenize special characters. Say I have the word "H&R Blocks" I want to tokenize it as "H", "R", "H&R", "Blocks" I read this post http://www.fullscale.co/blog/2013/03/04/preserving_specific_characters_during_tokenizing_in_elasticsearch.html . It explained how to preserve the special character. 回答1: Try using the word_delimiter token filter. Reading the docs on its use you an set the parameter preserve_original: true to do

JWT (上):认识 JSON Web Token

匆匆过客 提交于 2019-12-11 01:15:21
什么是 JWT? JSON Web Token(JWT)是一种开放标准(RFC 7519),它定义了一种紧凑且自包含的方式,作为JSON对象在各方之间安全的传递信息。这个信息可以通过数字签名进行验证并信任。JWTs 可以使用密钥(结合HMAC算法)或者 使用RSA、ECDSA加密的公钥私钥对进行签名。 尽管JWTs能够在各方之间也提供安全加密,但是仍专注于签名Token。当其他方隐藏了加密Token的某些声明时,签名Token可以验证声明的完整性。当Token使用公钥私钥对进行签名时,这个签名还能证明只有拥有私钥的一方才是签发它的一方。 什么时候使用 JWT ? 授权 :这是JWT最普遍的使用场景了。当用户登录之后,每次请求都包含JWT,允许用户访问那些只有携带token才能访问的路由、服务、资源。如今在单点登录中广泛使用了JWT,因为JWT体积小,且能够在不同域名之间被使用。 信息交换 :JWT是一种在各方之间安全传输信息的好方式。因为JWTs能够签名,比如使用公钥私钥对,你能够确定发送者的身份。另外,签名是使用header和payload计算而来,所以你也可以验证内容是否被篡改。 JWT的结构 jwt 包含三部分,之间以点(.)分隔 Header(头部) Payload(负载) Signature(签名) 一个典型的jwt如同下面这样: xxxxx.yyyyy.zzzzz

一、总体概述 本文主要介绍了由本人开发的、基于百度AI的云猫OCR软件的主要功能,性能评价及核心代码解读。因为是几个帖子合并成一个,所以篇幅较长,希望各位能耐心看完,当然也可以各取所需。 本文主要分为以下几个部分: 第一部分是云猫OCR软件介绍。 由开发者本人亲自介绍软件的主要功能。对标ABBYY等OCR软件,云猫OCR的功能更全面,使用更简单,关键的是云猫OCR目前是完全免费给大家用的。当然因为是试用版,可能存在一些bug,大家使用的时候不要乱按就行。云猫展示版本的下载地址见帖子: https://ai.baidu.com/forum/topic/show/955975 第二部分是云猫OCR基于百度OCR的具体实现方式说明。 同时也会对软件的部分核心代码进行展示,便于大家进行参考做出更有创意的产品。 第三部分是云猫OCR使用说明及效果评测。 但因为云猫OCR是2017年底左右开发的,所以用的不是百度OCR最新接口功能,如果云猫能得到大家的支持,我可以考虑开发新版接入更多百度最新的AI接口,希望大家能多多捧场。 本文的最后部分是附录,附上了我基于百度OCR进行开发的代码解读,使用的是最新的百度手写体识别接口,也一并打包给大家参考。 第一部分 云猫OCR的软件介绍 一、云猫OCR简介 云猫OCR是基于百度云OCR算法,由进击的狐狸进行开发的一款软件。本软件由C#语言进行开发
