It’s a fairly small change, but one that may mean much. The versions I just pushed out include an icon on the toolbar, plus sometimes a special button, in order to download encrypted and decrypted files loaded in the box as a link. This gets around the file size restriction of the right-click and “save as…” method that was used until now, especially on Chrome. I’ve been able to load and save files over 1 GB in size. Then you can attach them to a regular email, for instance. This affects the following apps: PassLok Privacy, PassLok for Email, PassLok Universal, FusionKey, SeeOnce, and URSA.
It’s been a while without an update, but now here’s one that may be bigger than it appears at first. PassLok has moved to version 2.5, which allows users to share their Locks with friends nearby via a QR code. The picture here contains my Lock, in case you want to communicate with me through PassLok.
Besides the surface war in the Ukraine, another war is being waged in cyberspace. Both sides have zero-day exploits that they’ve been waiting for the right moment to use and you may be affected by some of the shrapnel. Here tell you some simple ways to be prepared for a personal cyber Holocaust.
Quite some time ago, I wrote an article discussing the practicability of using a file as a key for encrypting other files. As I am preparing a talk on what can you possibly do if you find your computer compromised, I thought I’d optimize the tool in that article. A couple weeks later, the result is considerably faster and more powerful than the original. At least, enough to warrant a new article. So here it is.
A while ago, I got very paranoid about my computer being bugged, and so developed a series of paper and pencil ciphers that I published on this blog. After letting them sit for a while, my favorites from the bunch are FibonaRNG, a stream cipher seeded from three words which has formed the basis for the Human encryption mode in PassLok, and Snake, which achieves something close to the absolute impregnability of the one time pad by using a simple piece of text. In this article, I go through additional calculations related to Snake, and find that this cipher appears to be even better than previously thought. Read More
Yesterday a friend came to me in a rather vehement state of frenzy because people were getting spam from his email account. A quick trip to haveibeenpwned confirmed that, indeed, his email address was listed in recently discovered breaches. Fortunately, his password had not been compromised so the damage was relatively minor. But when I checked my own “low security” password that I still use in a number of places, the test was positive. This means that a hacker could just waltz into those accounts and order ukuleles that I don’t want, or impersonate me in some forgotten forum that nevertheless still has followers (including the FBI), and get me into a heap of trouble. So I decided to change all of those passwords and get it over with. Read on if you’re curious as to what happened. The picture should give you a hint. Read More
For quite a while now PassLok Chat has been one of the ways you can set up a real-secure real-time online meeting. This was done through the Chat option in PassLok, which generated an encrypted link to PassLok Chat. But now you can also enjoy PassLok Chat without the encryption step. This little app will generate a new chat link every time you click its “Make Chat” button, without asking you for any passwords or accounts of any kind. Share the link to enjoy free, unlimited, direct peer-to-peer conferencing without any accounts or servers in-between.
Like many of you, I’ve spent several weeks locked up “working” from home, which I’m putting in quotes because it does feel quite a bit different. One of my favorite helpers is Zoom meetings, because it’s so easy to use. But apparently it’s not so secure when it comes to holding confidential meetings and conversations. I’ve researched a few alternatives, and in this post I show you how you can combine them with my own PassLok in order to achieve a moderately secure connection. I actually started writing this before updating PassLok Chat to version 2 (this is the real-time conferencing solution built into PassLok and compatible apps), so I had no particular interest in promoting one method over another, including PassLok’s built-in conferencing.

These days, lots of people are communicating with each other via video conferencing, but it seems a number of popular video conferencing services are less than secure. Zoom, in particular, has come under a lot of fire recently because of the ease with which interlopers can get into ongoing meetings. You probably know that PassLok has had its own way to create secure chats for quite a while, but now it has been completely redesigned for version 2. This version works more reliably than before, and now includes the option to initiate Jitsi chats. Read More
