Portable folder encryptor? Crack it - China DOS Union Forum

I happened to see a folder encryption tool online, which was boasted very powerfully, as follows

 A high-strength folder encryption software, which can conveniently encrypt any folder, and supports USB flash drive encryption and mobile hard disk encryption.

This software has a simple interface, simple operation, powerful functions, and super performance. It is the best encryption software to ensure your data security.
Usage introduction:
1. Adopt the latest encryption technology, which can conveniently and quickly encrypt any folder, USB flash drive and mobile hard disk
2. The mature 256-bit BlowFish encryption algorithm can effectively protect your important data
3. The encrypted folder has characteristics such as anti-deletion, anti-copy, and anti-size viewing
4. Multiple encryption strengths can meet the encryption needs of different levels of users
5. After encrypting the USB flash drive or mobile hard disk, it can be decrypted on other computers without installing this software

The software is simple to operate, excellent in performance, and the encrypted folder has functions such as anti-copy, anti-deletion, and anti-size viewing. I believe it is a boutique software worth collecting.

I thought it was really a high-tech product, but unexpectedly, after a test, it was just the usual techniques we often use. It felt really naive and completely cheated the general public. Despise it! Now I will post a cracking batch processing. I did the experiment with its latest version 5.42. I have no mood to look at other versions, and looking at them is also garbage. If a certain comrade is using this program, please be careful. One day I will compile a truly high-strength encryption software for everyone.

The encryption software that are free online are basically operations of moving folders. WinRAR can be simply cracked. The landlord can try this. microsoft private folder

Looking forward to the big work of the LZ owner on the encrypted folder. It would be best to have source code for everyone to study, discuss and improve... Hehe. Although currently there are strong encryption software, like winrar, PGP desktop

When I wrote it, I didn't pay attention to choosing the encryption method. I tested it with the default lowest level method, which means the batch script posted in the post can directly restore it. This is my mistake; Recently, a netizen contacted me on QQ, saying that the entire disk was encrypted with a "higher" strength encryption method. Only then did I re-examine this software and wrote a VBS script to decrypt it, which is the second file in the attachment. As for the third one you mentioned, I had an idea at that time to directly modify its password, so that the latter two encryptions can be restored with his own software, but I haven't had time to do it yet. I'm busy with work these days. I will try it when I have time.
