I have a bunch of files in a cloud account that I have, at some point, encrypted before uploading them, but now I can't remember what I used to encrypt them. However the file (re-)naming system looks like other people might recognise what software I used... [more inside]
Is there a corporate grade storage device (NAS/SAN) that comes with functionality to prevent all data from being deleted and the only way to access the data is to export it and wrap it with a mandatory password security? More details inside [more inside]

I use Macs. I use a flash drive to carry powerpoint presentations and other documents that I need to access on PC's running various flavours of Windows, which are not mine and I will not have administrator access to. Is there a way that I can protect/encrypt the drive in a way that will let me use it on both systems, without having to pre-install software on the Windows system? I do not need government-grade encryption, just something that will stop casual snoopers accessing the data if I lose the drive.

I used to use Truecrypt to encrypt little enclosures so I wouldn't have to worry about my files so much when I, say, put them on a USB stick or backed them up to the cloud. There was a whole... thing with Truecrypt and now it's hard to say if I should use it anymore. Is there another program that's going to work well for this purpose? [more inside]

Recently I noticed a lot of controversy about whether Truecrypt is secure or not. It looks like their webpage is raising concerns about it, even to the point of suggesting that people migrate their data away from it. Arstechnica and others are following the story. What's going on? Might this be a hoax? Are truecrypt encrypted flashdrives not safe? If not, what level of security do they provide, if any? What would be a good alternative if we are to migrate away as quickly as possible?

I've only worked in a small business (15-20 employees) since I got out of school, and I've handled the technological necessities since I started because nobody else could. I've handled things on an as-needed basis: troubleshooting problems, setting up new computers, maintaining an iron grip on software installations, setting up the network and administering simple network devices, etc. However, I'm completely self-taught, and I have no idea if my hacked-together system looks anything like a properly-implemented corporate IT system. So I want to know what one looks like. Specifically, I'd like to know if there are any resources I can check out on my own that paint the picture of what I should be trying to achieve. NOTE: I'm NOT averse to hiring an outside IT firm or consultant to help with specification and implementation. However, I don't want to be at the mercy of a firm's "knowledge" and my own ignorance; you can waste a lot of money that way, regardless of scenario. [more inside]

Everywhere on the web there is discussion of B&N's great deal on the Nook HD+ for Father's Day. I took the bite and picked up the 16GB (comes w/micro sd port). So far, so good. My questions are: 1) Is there full tablet AES encryption for these? 2) Since B&N finally opened up the Nook and it's now compatible with Google Play's App Store, is there really a reason to root it? And a question about iMessage alternatives. (More inside) [more inside]

This envelope with a letter inside was found inside a large decaying bound edition of Shakespeare auf Deutsch in a junk shop in Bushwick that was only apparently open for a few months before disappearing. The letter, postmarked 15 March, 1939 - was sent to Paris by a Mr. Henri Wolf. The contents of the letter appear to be German shorthand. Included was small piece of what looks like code, there's nothing else on the back.The letter, envelope, postcard, etc in question are at this imgur album. Hivemind: What the hell is this?

Looking for a community/forum where I can learn more about networking, code, security, and OS-independent CS topics
I'm looking for a forum where I can ask questions about networking, security, coding, operating systems, web design, etc. There are many of these out there, but I'd like to find a single community which covers all these topics more or less equally (so it isn't a Linux forum with a small section on BSD, or a coding forum with a small section on networking). I'd like it to be the sort of forum where users stay around for several years as they learn and contribute at different levels, with high literacy and education-to-spam levels. Could I have your recommendations please?

A number of technology experts have criticized the iPhone's implementation of in-built hardware encryption. Apparently, circumventing it is a trivial matter of docking it to an Ubuntu system and making a drive image. For someone who knows what he is doing, it would take only a few minutes. How secure, however, is the "Erase all Content and Settings" option? If I understand correctly, this works by simply wiping the encryption key thus rendering all data useless to an intruder.

I'm tasked with attempting to build a secure virtual appliance. Problem is, I'm trying to stop people from gaining root access to the appliance via single user mode. This leads to a need for disk encryption, any ideas on how to create encrypted disk that wouldn't require someone to put in a password (plug in usb, interact with the boot process) to boot and still be relatively secure?

How are passwords stored in systems that require the user to enter specific digits of their password?
How are passwords stored in systems that require the user to enter specific digits of their password? I am familiar with encryption techniques such as MD5 hashes, but I can't see a way in which a system would store the entire encrypted password, and still be able to authenticate individual characters, unless the password is stored in plain text, which seems unlikely for a bank.

I need to password protect a section of the website I built (Mac OS X, Dreamweaver CS4) for my daughter's very small nursery school. Our web host is suggesting we buy a SSL certificate. The information I'm interested in protecting is the names, addresses, phone numbers and email addresses of about 60 people - do I go with 128-bit or 256-bit encryption? 256-bit is more than twice the cost of 128.
