What does it mean? Encrypted document.?

Question

I found a document on my pc (belongs to my brother, since we share pc) and the document status says: 'this document is encrypted and may use security features that prevent you from modifying certain aspect of it'. What does it mean really? Sorry, i'm not really good on this computer stuff.

Answer 1

Encryption is used to prevent access by other users. http://en.wikipedia.org/wiki/File/folder_encryption

Answer 2

I know I've mastered the ability to walk, talk and read. There's nothing much left to learn in these fields, and I can do it all with complete ease. Doesn't mean I never stub my toe, slur a few words, or stumble on a sentence now and then, but I've reached a point where it's completely causal. I'm not an olympic sprinter, or a public speaker, or a speed reader -- those are all entirely separate skills -- but what I learned is plenty to get through life. I never forget that the martial arts are called an art, whether or not that's an Eastern interpretation, but in the West this does have a purpose. An art couldn't be something you perfect. Music, painting and sculpting all have near limitless potential, but stages of development that you would have to "master" to get better. A black belt, as we've explained before on here, is about having a firm understanding of the fundamentals, or "All basic movements and techniques, can be applied with extended force and proper application in basic combination." The key words here would be "all basic movements and techniques" and "extended force and proper application". I would say there is a mastery of having LEARNED the requirements and KNOW how to put them to use, just not anything further from the basics. I think people go a little too far with the word, using it mostly erroneously, but the intent of comfortably and casually using what you've learned is what they're all implying. As for the martial arts as a whole, that I believe is impossible, especially as an art.

Encryption is a process where the data of a file is scrambled and a specific key and process is needed to unscramble the data. Windows is telling you that the file you tried to open has been scrambled and you don't have the key to open it.

Likely this document was in his MyDocuments directory or a similar User Specific location. Windows can be setup to not allow other users access to your personal documents. It is quite possible that your brother has no idea that his files are encrypted. He would not have to do anything special to un-encrypt them and use them.

Answer 4

It means that this document is protected from unauthorized viewing, and/or modifying. The document is saved in a way that only the owner (in this case would be your brother) can access it without limits.

- There are several encryption/decryption (decryption leaves de document unprotected) methods, in order to encrypt or decrypt a document , a password or keyword is usually needed. -

Answer 5

An encrypted document is one which has been passed through a mathematical algorithm in order to alter the contents of the document to make it unreadable.
A knowledge of the algorithm and an associated key(password) is required to decrypt the document in order to read it.

Answer 6

Your brother "Save file as..." Encrypted (jumbled data) and used a password, so others can't open the file.
