Encrypting Text Messages and Email Content with Paranoia Text #Encryption (PTE) #FOSS #free

Objective: Securely encrypt your email message content and/or information in GoogleDocs word processing, or text messages. This works on your Windows, Mac, Linux, Android or iOS devices.
Step 1 - Get Text Encryption (PTE) Tool  for Your Device Get the iOS (iPad/iPhone) version of PTE Get the Android version of PTE (built-into SSE) Get the Mac/Windows/Linux version of PTE
Encrypting text is pretty easy. You can type it up in a word processor, email window, or text editor, then copy-n-paste it into the PTE window (the top one, as shown below, with decrypted text).
Tip: You wouldn't want to type up your secret to-be-encrypted text in any cloud service since it's automatically saved on cloud servers. This is true for Evernote, Gmail, GoogleDrive, etc.
Step 2 - Launch PTE and begin Encryption Process To accomplish the encryption, click on ENCRYPT and you'll get the encrypted text. Note that although there are various choices for encryption algorithm, I'm going to use AES (256 bit)…

Encrypting Files and/or Folders with Secret Space Encryptor (SSE) #FOSS #free #encryption

Objective: Securely encrypt your private and confidential files or whole folders. Wiping (secure delete) feature is included for computer and Android versions.
Step 1 - Get Secret Space Encryption (SSE) for Your Device Mac/Windows/Linux computer?Get the cross-platform version of Secret Space Encryptor (SSE). Android device?Get Secret Space Encryptor (SSE) for Android from Google Play store. Note that Secret Space Encryptor isn't available for iOS (e.g. iPhone/iPad) devices, so you'll need to take that into consideration.
Step 2 - Encrypt and Decrypt Files with SSE To encrypt files--that you add or attach to email or store on various media (e.g. hard drive of computer, external USB drive, network backup), you can use the Secret Space Encryptor (SSE). You can choose to encrypt files individually or drop them all into a folder and encrypt them all at once as ONE file.
All encrypted files have the filename extension of enc so you will know when they are encrypted.
When you launch Secret S…

In a series of tweets in response to my post--Not Alone: Inflexible CIOs = Failure-- yesterday about Tim Stahmer's entry about CIOs and Technology Departments blocking curriculum educators from using Chromebooks yesterday, these two statements were made:

Tim Stahmer@timstahmer@jeannereed1 For whatever reason, we tend to forget students when discussing many parts of education, tech included.

@mguhlin@timstahmer Does over-worked, under paid IT staff lead to forgetting about helping students? Crazy.
To speak to Jeanne's question first, Are over-worked, under-paid IT really the problem in the scenarios described in Not Alone? When you consider Tim's scenario, it's not about Chromebooks, how easy they are to manage. Rather, it's an issue of control. 
The CIO and Tech Department aren't refusing to support Chromebooks because they are difficult (I don't know any CTOs who would argue that Chromebooks are difficult to manage), but rather, becaus…

Not Alone: Inflexible CIOs = Failure

Over at Assorted Stuff blog, Tim Stahmer (@timstahmer) shares a real story--Chipping Away at the IT Barriers--about how IT staff--led by the CIO--didn't want to support a particular mobile device. However, this time, the leaders in charge didn't take "No!" for an answer and did an end-run around the entire Technology Department, obtaining support to buy the equipment.
A small group of principals here in the overly-large school district decided to bypass the usual bureaucratic channels, along with all the IT denials, and took their case for Chromebooks to directly our Deputy Superintendent (with a great deal of support and encouragement from our little cheering section).
To our surprise, he approved their proposal to purchase a limited number of the Google-based devices to test in their schools. The initiative only involves a few classrooms in five six schools so we certainly aren’t talking about any major shifts in thinking. But potentially it does represents a big …

School Talk: When Communications Fail @Telegram to the Rescue

Communication apps are transforming how we interact, keeping us in touch, helping us share learning and ideas as they happen, as well as engage safeguarding communications from governments and others. At the bottom of this blog post, you will also find a chart created by Texas Area 13 school districts that shared their insights into what tools they use for communication.

One app that I've embraced, both for family communications as well as at work for emergency communications, is Telegram. If you're not familiar with Telegram, it's a cross-platform app that allows for audio/text group chats, broadcast messages, as well as one to one encrypted communications. In my family, we use the no-cost Telegram as an alternative to WhatsApp and SMS messaging. And, when secure communications are needed, Telegramgets the job done, too.

In one school district, here's how I've advocated its use:
Thank you for your attention to this information. As you know, the District occasionall…
