【300分】求一个php解密算法

以前采集的一个站最近联系方式用图片来生成了,导致联系方法无法采集到。

http://www.guijob.com/securite.php?contact=AQUAChwGAAsABAQL
输出到图片的内容:0773-2181632

http://www.guijob.com/securite.php?contact=AQUAChw
输出到图片的内容:0773-

更多内容可以参考这个页面的:http://www.guijob.com/display/jobs/87859.htm

内容应该就是红色的部分,只是被混淆过了,大家随便输入字母会得到不同的图片内容

php只了解皮毛,不知道如何解密。


由于在php论坛等级不够,无法发300分的帖子,我会慢慢加上去的,不行发另外2个100分的帖子给提供思路的童鞋


------解决方案--------------------
直接将图片存入数据库?
------解决方案--------------------
有的时候是两个字母代表一个数字,有的时候是一个,两个字母有不同的组合也能代表一个数字
如果单独重复的输入ADADAD这样,结果也不是连续的数字
如果输入密码的后半截,输出也不是后半截数据,而是其他数据
暴力破解似乎不太好办,不是密码表,求解算法
------解决方案--------------------
与其花力气去解加密方法不如图片识别 这种图片识别率是100%...

人家的加密算法除非是写得简单了,若不然想轻松解出来并不容易.
------解决方案--------------------
掉坑里的路过,这玩意似乎是靠位数识别的
AQUAChwBCQQDCw4J是0773-5872990
AQUACAQBCQQDCw4J是077155872990
第6,7位的小写hw可以成为短横线,但也会影响到前面的数字,但不会影响后面的
------解决方案--------------------
测试了几把,应该是对ascii动的手脚,不过我不擅长加密解密。

提供下思路,看看有没有数学高手能找出规律。

楼主提供的:AQUAChw,对应结果为0773-
我尝试去掉w,尝试AQUACh,得到结果为0773
但是单独输入个w,什么结果也得不到,可见w !== -

因此我认为他很可能是整体处理的。

拿AQUACh来说,对应的ascii为65 81 85 65 67 104

我认为他可能是将这个数字列先用什么计算方法合并在一起,再得到0773这个数字的。并且我确信,这个转换也是得到ascii码后再找对应字符的,因为其中不止有数字,还有一些特殊字符。

What are the advantages of using a database to store sessions?What are the advantages of using a database to store sessions?Apr 24, 2025 am 12:16 AM

The main advantages of using database storage sessions include persistence, scalability, and security. 1. Persistence: Even if the server restarts, the session data can remain unchanged. 2. Scalability: Applicable to distributed systems, ensuring that session data is synchronized between multiple servers. 3. Security: The database provides encrypted storage to protect sensitive information.

How do you implement custom session handling in PHP?How do you implement custom session handling in PHP?Apr 24, 2025 am 12:16 AM

Implementing custom session processing in PHP can be done by implementing the SessionHandlerInterface interface. The specific steps include: 1) Creating a class that implements SessionHandlerInterface, such as CustomSessionHandler; 2) Rewriting methods in the interface (such as open, close, read, write, destroy, gc) to define the life cycle and storage method of session data; 3) Register a custom session processor in a PHP script and start the session. This allows data to be stored in media such as MySQL and Redis to improve performance, security and scalability.

What is a session ID?What is a session ID?Apr 24, 2025 am 12:13 AM

SessionID is a mechanism used in web applications to track user session status. 1. It is a randomly generated string used to maintain user's identity information during multiple interactions between the user and the server. 2. The server generates and sends it to the client through cookies or URL parameters to help identify and associate these requests in multiple requests of the user. 3. Generation usually uses random algorithms to ensure uniqueness and unpredictability. 4. In actual development, in-memory databases such as Redis can be used to store session data to improve performance and security.

How do you handle sessions in a stateless environment (e.g., API)?How do you handle sessions in a stateless environment (e.g., API)?Apr 24, 2025 am 12:12 AM

Managing sessions in stateless environments such as APIs can be achieved by using JWT or cookies. 1. JWT is suitable for statelessness and scalability, but it is large in size when it comes to big data. 2.Cookies are more traditional and easy to implement, but they need to be configured with caution to ensure security.

How can you protect against Cross-Site Scripting (XSS) attacks related to sessions?How can you protect against Cross-Site Scripting (XSS) attacks related to sessions?Apr 23, 2025 am 12:16 AM

To protect the application from session-related XSS attacks, the following measures are required: 1. Set the HttpOnly and Secure flags to protect the session cookies. 2. Export codes for all user inputs. 3. Implement content security policy (CSP) to limit script sources. Through these policies, session-related XSS attacks can be effectively protected and user data can be ensured.

How can you optimize PHP session performance?How can you optimize PHP session performance?Apr 23, 2025 am 12:13 AM

Methods to optimize PHP session performance include: 1. Delay session start, 2. Use database to store sessions, 3. Compress session data, 4. Manage session life cycle, and 5. Implement session sharing. These strategies can significantly improve the efficiency of applications in high concurrency environments.

How do you configure the session name in PHP?How do you configure the session name in PHP?Apr 23, 2025 am 12:08 AM

In PHP, you can use the session_name() function to configure the session name. The specific steps are as follows: 1. Use the session_name() function to set the session name, such as session_name("my_session"). 2. After setting the session name, call session_start() to start the session. Configuring session names can avoid session data conflicts between multiple applications and enhance security, but pay attention to the uniqueness, security, length and setting timing of session names.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
