I spent a whole night writing this.Code, A little messy. Sorry.
The first is the abstraction of encryption and decryption, because. net implements 3DES very well and does not support string, so we must encapsulate it as a 3DES Encryption Class that can use string as key, IV, input and output. This is very important, encryption and decryption of cookies and encryption and decryption of URLs depend on it.

encrypted DVD files. This copy stores all extended VOB files in the hard disk for decryption. Because the video is not encrypted during playback, the files stored on the hard disk are not encrypted.
With DeCSS technology, we can copy a DVD disc to a hard disk regardless of whether it is encrypted or not, but the software that uses DeCSS technology needs to be used to encrypt the copy of the DVD. The software in this area includes DeCSS1.21b, CladDVD, De-MPAA, SmartRipper 2.41, and DVD
Recently, I want to add a JS prompt box on the homepage of the main site. After searching for a long time, I finally found a very helpful JS prompt box;
The implementation is very simple, and the effect is great. Now, I hope to help you.
The content of the boxover. js file is:

In the ESD format, Microsoft began using a new system image file compression format in Windows8, a higher compression rate than WIM, but currently only DISM supports the processing of ESD files. In addition, most of the ESD files are encrypted and DISM cannot be processed directly. So the best way to do this is to decrypt the ESD file and convert it into a WIM or an ISO format image file that contains a WIM.

if (!this. Locky) this. Drag.style.top = itop + "px";
Horizontal and vertical locking: You can restrict the top and left properties for the Lockx and Locky properties by judging them.

Drag and Drop lock]
There are three types of locks: horizontal lockx, vertical locky, and full lock ).This is relatively simple. for horizontal and vertical locking, you only need to determine whether to lock in move and then set left and top.
