I have always shared the idea of this tool class, just because I don't have time to sort it out, so I haven't posted the code. This is an easy-to-use method.MD5+ Salt-encrypted tool class. Some codes are searched on the Internet, and some of them are modified and added. This tool class is very simple. You can get the passwd password from the front-end and direct

Introduction to ASP original code encryption toolThere will always be very many ways to expose the ASP's original program. Because the password path of the database can be easily got by others, it is a good solution to encrypt the ASP program.

Create a dingtalk encryption/Decryption tool in Python and decrypt it in python. I haven't written a technical blog for a long time. Because I have been learning knowledge recently and have not summed up anything worth sharing, I have been suspended. Recent work and dingtalk development have been handed over. The official website does not provide any Python SDK, so you can only write it on your own. Now I w

The business secrets contained in Oracle stored procedures are sometimes unwilling to be seen by third-party personnel. They can be achieved through encryption of stored procedures. There are two methods to encrypt the stored procedure: here we will focus on wrap: WRAP is an operating system-level command provided by Oracle. The principle of its encryption is to first perform LZ compression on the source co
