I encountered a piece of PHP encryption, but I really don't know how to decrypt it. I want to ask the gods to have BASE64 and some garbled characters. I really don't know how to decrypt it.
Because a forum with special characters cannot be sent up, the network disk address will be sent.

Asp.net and java are used to encrypt and decrypt des, asp. netjavades
Recently, a new project was developed in java. The old project is asp.net, and the interface transmission requires des encryption and decryption. I checked some information on the Internet and most of the information can't be used, after debugging and processing, the specific code is as follows:
The key must be 8 bits.

Brief introduction
This article will teach you how to build a component that can add/decrypt data using Visual C + + and the ATL tools and Microsoft CryptoAPI.

This article uses microsoftreg; Cryptographic application Programming Interface (CryptoAPI) hides the bitter and difficult logic algorithm operations, and if you want to know more, see MSDN Library. If you want to know more about cryptography, I recommend you look at this book. Bruce

In this tutorial, we will first talk about available characters in PHP variables because we want to decrypt the program encrypted by Alibaba Cloud Security. Understanding the available characters in PHP variables is the primary condition for decryption, go directly to the topic and talk about the naming rules of php variables. Baidu will take the following measures:
(1) PHP variable names are case sensitive;
(2) the variable name must start with the d
