encryption

I see they have a program that can break or compromise web security. http://www.theguardian.com/world/2013/sep/05/nsa-gchq-encryption-codes-security Assuming I use GPG to generate a 2048-bit key with a good pass phrase, and do all my encryption/decryption offline to produce email attachments...

Is there some kind of encryption that would cause documents to become permanently corrupted if they were copied onto another drive? Or something similar? I don't need to do this, I'm curious about it for a storyline, and I'm not savvy enough to be able to figure out the possibilities...

In trying to understand asymmetrical encryption, I thought of a way to do it that doesn't involve large prime numbers. If someone can explain to me why it isn't done in the way I thought of, I'll have a firmer grasp of the way it's actually implemented. So, Person A wants to send a secret email...

Does someone in here know how to burn down working TrueCrypt [*.tc] files? I burned a DVD with my private encrypted Data by burning down the *.tc - file itself. Now after doing so I mounted the *.tc file on my DVD but if I try to access the mounted volume via the WinXP Explorer all I get is an...

Here's a bit of a different twist on email security, and I'm asking if anyone is familiar with a program to do what I want it to do. I have a friend of mine that does taxes and wants to send tax drafts out to his clients, but wants them to be secure. I am familiar with digital signed messages...

I downloaded and installed the latest version of WinPT today. I generated a new key pair, and figured out how to encrypt/decrypt files using the file manager. But when I encrypt a file, the original remains. What am I supposed to to with that? Throw it in the trash? LOL, that would make it...

It seems to me someone is always breaking the encrypted description for the contents of the remote viewing locker. I sent Mr. Randi the following, and it would be interesting to see what others had to say about it.

I bought one of those small usb "drives" to bring files back and forth from work, and some of the files I use with it, budgets and stock info, I'd rather keep private. Does anyone know of an encryption program that could be run from the portable drive and does not have to be installed on the...

Come on with these silly "codes" Randi! Enough of this ISBN and your trick-letter cyphers. There are plenty of people here who can break codes. This one better be better than ENIGMA, because, you know, some of us on here KNOW how to use COMPUTERS and MATH. Just use public-key encryption and...
