This is really complicated~

The Unicode corresponds to 0xFEFF, the Unicode BIG ENDIAN corresponds to 0xFFFE, and the UTF-8 corresponds to 0xBFBBEF. These several bytes are called BOM (byte order mark). If a file has a BOM, Notepad directly uses it to determine the encoding; otherwise, it determines the encoding according to the content of the file.

From last year to this year, this post just doesn't sink. It seems that everyone is really concerned about encryption.

I also really want to learn, but after browsing all the posts, I find that none can really achieve encryption.

But the method similar to "variable encryption" like a key should be the most perfect development direction, but no one has made a mature thing yet.

I hope experts can make a tool for key encryption!

Wonderful....

Hey~~ I don't know, when will this little bird of mine finish digesting?

Previously seen, this code seems to be able to encrypt batch processing

Can't download.. Depressed because points are insufficient

Can't download. Depressed because of insufficient points

Is there any better method?

Is there any better way?

Wow. Why are all the posts repeated!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I'll also give it a boost. Recently, I wrote hundreds of lines of code and also want to encrypt it.
