Js/vbs/vbscript encryption code:
Note: Copy the content to be encrypted to the If a running error occurs,
Step 2: perform a test to encrypt the above Code using js. The encryption effect is as follows:
In fact, we can decrypt the source code based on the above encryption source code. The Code is as follows:
At this point, our decryption is complete!Js/vbs/vbscript common decoding!
Download the ASP source code from the Internet with great enthusiasm. once a file is opened, tianshu-like encryption code is displayed. it's depressing. I found the decryption method on the Internet. I had to open, copy, paste, decrypt, copy, and paste a file one by one, save ...... if an ASP program has hundreds of files ???
There is a solution ..

Alibaba Cloud security guard is always suffering! After studying for a long time, I also consulted some netizens (the Mars giant panda of cnblogs), but was told that the official encryption algorithm of Alibaba Cloud security guard was upgraded and cannot be decrypted in the old way. C/C ++ programmers have little knowledge about the encryption and decryption principles, that is, they cannot decrypt the encrypted software. But later research found tha
An error occurred while deploying the report:The Report Server cannot decrypt the symmetric key used to access sensitive data or encrypted data in the database of the Report Server. You must restore the backup key or delete all encrypted content. For more information, see this document.
Solution: delete all symmetric key instances and all encrypted data in the database of the Report Server, and then recreate the encryption key.

The following code indicates the encrypted version. In addition, // 0046a does not indicate the encrypted version. The younger brother finds many loncube decodes on the internet and cannot use them. I don't know which eldest brother can give me some advice, it is better to have tools to share. thank you first.

Which of the following lines is incorrect? you can fix them by referring to other files.There should be no problem elsewhere.

You can try js:For example, JavaScript code involves three functions: escape, encodeURI, and encodeURIComponent. the corresponding three decoding functions are: unescape, decodeURI, and decodeURIComponent.
