Quick Encryption/Decryption Utility

Need a quick program to encrypt or decrypt small amounts of text, such as passwords? Here’s a quick utility I wrote in Python using Google Colab, Google’s implementation of Jupyter Notebooks. You can run the program there or copy it to your own Google Drive first. Note that you’ll need a Google account to access it.

I personally use this utility to encrypt sensitive information in Google Keep, as shown in the screenshot below. I save the URL of the utility with the encrypted text so I can decrypt it quickly.

(For longer notes, I’d honestly recommend a proper password manager that can encrypt notes. I use the Premium version of Bitwarden, which I highly recommend.)

The instructions in the program should be adequate to run it on your own.

Bookmark it in your browser for quick access! (Ctrl-D on your PC or Command-D on your Mac)

Converting Lists of Data to CSV — Using a Colab Notebook Hosted in Gists

I’ve really been enjoying learning about data analysis lately. Part of what’s made it so enjoyable is the use of Colab, which is Google’s version of Jupyter Notebook.

I came across a need to convert some lists of data to a CSV (comma separated values) format so I could paste it into a Google Sheet. Not finding anything online to do I decided to write my own, and here is the product.

The Colab notebook I created has been saved as a “gist”, which is GitHub’s cousin for fast and easy file storage service. The Gist website is also very popular for sharing CSV files, which this search will attest to.

You’ll notice an “Open in Colab” button at the top, which is how you will open the document. A really nice feature is that it is fully usable without needing to save the file anywhere, but for those that do want to save their work, they can, into Google Drive.

When you first run it, you’ll get a scary message that was written by Google’s lawyers. You’ll see from the source code that the notebook’s not doing anything nefarious, so just trust me and click on “Run Anyway”. 😆

Google Colab Warning

This is a preview of the notebook. To open it, click here or on the filename on the bottom left corner of the preview.

Some Python programmers may want to remind me that I could have used Python’s built-in CSV library, but I felt Pandas would be faster, especially for large lists.

I hope some of you find this useful, although I’ll be happy if it gets some of you interested in Colab for Python programming or for data analysis, or even if it just introduces you to the Gist website.

Integrating Google Drive into Google Colab Notebooks

Why might we want to integrate Google Drive into Google Colab? The primary reason for this would be to easily access data files to use in your Colab notebooks. 

Here is a video that outlines the basic process. For written instructions, see below.

Integrating Google Drive into Google Colab is quite simple. The first step is to go to Google Colab, then open a new notebook.
