Announcing the Palm Strip Export Utility

2009-12-30 19:00:00 -0500


Back in 1997 we released the first version of our mobile password manager and data vault Strip (Secure Tool for Recalling Important Passwords) for PalmOS. It quickly grew to be one of the best and most widely recognized security applications for the platform, gathering accolades from the likes of ZDNet and CNN. A few years ago we dropped support for PalmOS Strip after the decline of the Palm platform. Then, last year, we resurrected Strip by bringing a completely redesigned system to the iPhone sporting a flexible data model and new open-source encrypted database engine.

Yet, many former PalmOS Strip users have let us know that they are still trapped on their old devices, in dire need of a way to export information from their Palm databases. Some people have switched to Strip for iPhone, others just want to back up their information in case of device failure.

Today we are pleased to release a free utility that can export your legacy PalmOS Strip databases out to a simple Comma Separated Value file. Once your databases are exported you can print them, open them in Excel or import them into a separate program. Most importantly, these export files will be directly importable to the iPhone when we release our first Strip desktop sync tool in the coming months.

How To Export

Note: This exporter only works with Palm Strip 1.0 or 2.0 Databases. If you are not running one of these versions you should upgrade first. This utility is not intended for use with the iPhone version of Strip (we will be releasing a iPhone sync package soon that will provide similar functionality).

Start off by downloading the exporter program:

Save the program to your computer and then run it:

  1. Enter the password for your Palm-Strip database. This is the same password you would enter into the program normally.
  2. Click the “Choose Directory” button, and navigate to the location of your Strip Databases. These will usually be in your Palm desktop install folder, usually something like C:\Program Files\palm\<username>\backups.
  3. Click the “Save As” button to choose the location to export the file.
  4. Click the “Export To File” button.

The system will then export your entire database out to a CSV file at the selected location. Your data will be left intact, with the exception that line breaks will be removed from Note fields to allow the export. Open your file in a spreadsheet like Excel or in a text editor like Notepad to verify the results.

Credits & Code

This new exporter tool is based on the pioneering work by David Dribin’s perl-strip, an early exporter for Strip databases. We’ve taken his great Palm::Zetetic::Strip module and forked it on GitHub. Our updates include the use of newer digest libraries and updates to support the full Strip 2.0 database format (including service types). We’ve also released the source to the palm-strip-export application on GitHub.

Gone Nomading? Try Coworking

2009-12-29 19:00:00 -0500

Terralien’s Nathaniel Talbott has an interesting article up on their blog about an activity they’ve termed nomading, or nomadic programming. Basically, Terralien is what you might call a remote company, in that a good number of their people work from geographically distinct locations, often not meeting in person but keeping in touch and coordinating their projects and work over the Internet. We work this way, too, so we’re always interested when other firms write about their experiences.

Talbott’s article is interesting in that Terralien is using this concept of nomading to help mitigate the problem of isolation one can experience remoting:

But no matter how much we appreciate the flexibility of working from wherever, we still often feel the need to spend some time in the same place with fellow geeks. The wife and kids can only take so many explanations of the latest cool hack we pulled off, and a change of scenery can really help get the creative juices flowing. As with so many other remote workers, we started heading out to a coffee shop on occasion, which was fun, but still didn’t quite cut it.

I can tell you from first hand experience that a year and a half of working out of my apartment was a pretty isolating and eventually depressing thing. I’m sure it’s not a problem for some people, but I think most people who try it for any considerable length of time run up against this problem. It comes down to a pretty simple notion — you need to get out of the house, and by the end of your work day, you’d ideally want to enjoy being home.

Terralien’s Matthew Bass, who coined the term nomading, describes how he arrived at his solution:

I don’t mind being alone to a certain extent, but after a few straight weeks it can get pretty lonely. Recently, I’ve started doing what I’ve termed “nomadic programming.” Namely, spending the day roaming between various wi-fi hotspots instead of working from home. This has worked really well for me. So well, in fact, that I think the concept needs to start spreading.

I actually disagree, having tried nomading when I started to get stir-crazy. While I do think it’s a good first step for anybody who’s been working in isolation, you quickly run into some problems doing this that make it a somewhat incomplete solution to the problem. There’s really nothing that comfortable about hanging out in one or more coffee shops all day long, buying obligatory coffees and snacks, using their power outlets under the glare of the manager, not being welcome for quite so long, flakey network connections, and finally, do you really want to leave that $2000 computer alone by itself in Cafe Grumpy while you go to the bathroom? Do you want to take it in there with you, for that matter?

Coworking has been the ideal solution for us here at Zetetic, as we’re now working out of two coworking locations, Williamsburg Coworking in Brooklyn, NY and Indy Hall in Philadelphia. One of our guys is planning to open a new space soon with some partners (so I can’t reveal any details), and our founder Stephen Lombardo has been thinking for some time of starting one in central NJ (if you’re in central NJ and you are interested, get in touch!). It makes us really happy, keeps us extremely productive, and we can’t recommend it enough.

We pay monthly fees to use our spaces — it’s a lot cheaper than renting commercial office space. We have ergonomic chairs, we have personal storage areas where we can keep keyboard trays and the like. We have a fridge, a kitchen, wifi, and a really fantastic social group of thinkers, artists, programmers, writers, you name it. Distractions are low, productivity is high, we have people to bounce ideas off of who’ve become our friends, we even prepare lunches together sometimes to save money (and because it’s fun, Zane’s a great cook). We even have an excellent library of somewhat “alternative” reading materials.

When I started working here, my productivity shot up like woah. In addition, I’ve learned how to screen print and pickle vegetables. I’ve made some great friends and I get to bounce ideas off extremely smart people. And this is a very large community — our space is part of a network of locations all over the world, and any of us is welcome at those spaces if we’re traveling (read more about Coworking Visa). I think the main reason people here get along so well is that there’s no one here who doesn’t want to be here, it’s the total opposite of being trapped in an office. And having done a bit of nomading myself, it’s a lot less stressful.

These coworking spaces are popping up all over the country, the world, and they work. They’re even potentially lucrative businesses, although I prefer our space’s non-profit setup. If you’re considering nomading, we encourage you to try coworking as well, you can find many locations by searching the wiki.

How to encrypt a plaintext SQLite database to use SQLCipher

2009-12-28 19:00:00 -0500

Note: the content in this post is outdated. Please use our new recommendations for how to encrypt a plaintext database with SQLCipher.

We’ve fielded several questions on the SQLCipher mailing list recently about how to convert a standard SQLite database to an encrypted SQLCipher database. This is a pretty common requirement for applications with existing databases that need to be converted to use SQLCipher full database encryption.

Attached Database (Recommended)

SQLCipher 1.1.1 added support for attaching an encrypted database to an unencrypted database to copy data between them. For instance, assume you have an standard unencrypted SQLite database called unencrypted.db with a single table, t1(a,b). To create an encrypted copy you could open up the databases and run the following:

ATTACH DATABASE 'encrypted.db' AS encrypted KEY 'secret'; -- create a new encrypted database
CREATE TABLE encrypted.t1(a,b); -- recreate the schema in the new database (you can inspect all objects using SELECT * FROM sqlite_master)
INSERT INTO encrypted.t1 SELECT * FROM t1; -- copy data from the existing tables to the new tables in the encrypted database

It is fairly trivial to get a list of all schema objects from the sqlite_master table you would just repeat the CREATE TABLE / INSERT cycle once for each table. Then you can delete the unencrypted database and re-open the encrypted version with the sqlite3_key or PRAGMA key. This approach requires more work that just calling rekey, but it is be much more stable across versions.

In the mean time, we are working on finding a way to improve the built in rekey functionality in future versions. Keep an eye out here, or join the SQLCipher mailing list to keep up to date on the latest development.

Improvements to SQLCipher - cross platform SQLite Encryption

2009-12-27 19:00:00 -0500

We’ve been really busy over the past week finishing up some big enhancements to SQLCipher, the open-source full-database SQLite encryption extension that powers Strip, our Data Vault for the iPhone.

The latest version SQLCipher 1.1.1, is based on the most recent release of SQLite (3.6.21), which has a many improvements and bug fixes. In addition the new SQLCipher features include:

  1. Code clean up to allow compilation with VS.NET on windows.
  2. Enhancements to the codebase to allow encrypted databases to be attached to unencrypted database for the purpose data migration
  3. Resolution of a minor memory leak in the pager subsystem
  4. Documentation and test enhancements

The newest build makes SQLCipher truly cross-platform – it’s now been used successfully under Mac OS X, iPhone, Linux, and Windows (across MinGW, Cygwin, and native VS.NET). The new version is a drop in replacement for previous releases, so we’re recommending that all SQLCipher users upgrade to the latest.
