The service provider has informed us that the testing site crysm.com must be shut down at the end of September. Students still interested in completing the program after that date should contact the Institute. We can make alternate arrangements for you to complete your requirements.
September 29, at 11:59 PM, GMT, is the cutoff time for taking and completing tests. In the continental US, that time falls in the evening of September 29: on the east coast, it falls at 6:59 PM.
Cryptosmith Institute now offers a second option for earning an NSTISSI 4011 training certificate:
- The original option: Complete exams on the 17 chapters in Elementary Information Security plus a final exam covering all material in the textbook.
- Students who have already taken a college-level cybersecurity course may skip the separate chapter exams and earn the certificate by taking the final exam.
Students interested in the second “streamlined” option must upload a college transcript showing the relevant course before they take the exam.

I am offering a Cybersecurity elective for students registered in the University of Minnesota’s Master of Science in Software Engineering program. As I described in the class on Friday, the course uses the textbook I wrote and does a lot of lab work with security tools, including Wireshark, nmap, Gnu Privacy Guard, and vulnerability scanning.
Here is a link to the 2015 syllabus.
The text attached to this post was submitted as a web site comment. No doubt some spambot was supposed to select randomly from the text to produce a unique-looking spam message. I know I’ve received lots of spam comments that this script might have generated: personal-sounding messages that are content-free.
I’ve used similar scripts to show how one could generate several different texts that all mean the same thing but contain different digital content.

Matthew Green published an entertaining rundown on the cryptographic back door in ANSI and NIST standards. He focuses on how it got there and why it’s still there, as opposed to its technical details.
I started collecting digital content in the 1980s. Before that I was satisfied to print things out, bind them, and put them on a shelf. My graduate research produced about three linear feet of printed papers sorted by author. I wrote my first book mostly from printed references, though all the writing was online. When I started my second book, Authentication, I decided to collect, catalog, and save my references digitally. I stored everything in a tree of folders, one per author, stored alphabetically.
My library now contains several thousand items, from Gutenberg ebooks to marketing brochures to technical papers. It uses over 8 GB of storage, including catalogs and metadata. I used to read classic fiction on Palm Pilots and early smartphones. Now I read everything from fiction to technical reports on a tablet, either Android or iOS. This environment poses a whole set of challenges. I’ve found some tools to make my library work, more or less: Calibre, OPDS, and DRM-free books.
My main objective is Get it Once, Organize it Once, and Read it Anywhere.

Phishing emails can be tiresome. Sometimes, though, they are classically bad. Even better, this one uses an old-school strategy to get you to click on a suspicious link.
The domain name is “nytijmes.com” which at first glance appears to go to a more-or-less legitimate news site. The extra “j” in “nytimes” is easy to overlook.

A few weeks from now I’ll throw the switch and redirect Cryptosmith web traffic to its new home.
For now, cryptosmith.com still goes to the old site, though popular content and the RSS feed go to the new site at b.cryptosmith.com.
It’s ironic that I’m moving to WordPress. My first site with a modern content management system was a self-hosted WordPress site several years ago. I migrated to Drupal a year or two later. I’ve had a terrific time with Drupal as a plaything, but I’m tired of maintaining it. My son Alex did web software for a few years and tried hard to move me back to WordPress.

I am moving my Cryptosmith web site to WordPress.com. This will give me a lot more time to work on content while wasting a lot less time on mucking with the site.
There are things I love about Drupal, but I hate having to manually replace a bunch of files each time they revise the core modules. I’m terrified to think that I might need to migrate from Drupal 7 to Drupal 8 someday. It was awful migrating from 6 to 7. So I’m jumping ship.
Cryptosmith.Com will now reside at WordPress.com. I couldn’t find a Drupal service that was anywhere as cost-effective as WordPress.com.
The old stuff is available at old.cryptosmith.com and cryptosmith.org.
