It's been a while since I last updated this blog. School and CCDC have really been eating at my time. Contrary to the earlier style of the blog, I plan on keeping things more informal and casual. I'm transitioning this into more of an archival type of thing. A place to keep track of my notes and projects, as well as a place to document my thoughts at the time. Posts will be infrequent and likely quite random. For this post, I'm going to write about a little port scanner I wrote for an entry-level C course. As a little background, the only experience I have with C comes from C++ in a high school course some 7 years ago. So I was fairly excited to start this class and dig in a bit deeper. The Project For our final project, we needed to create a program and present on it. I wanted to combine what I was doing in my networking class and my C class, so I went with something I thought would be simple enough. A port scanner. Turns out, writing a port scanner when the most advanc
PGPy is a library for python that enables the creation, storage, and encryption/decryption of PGP keys and files in python. Recently, in a small project to reacquaint myself with python, I used PGPy for key generation and encryption and decryption. That project can be found in my github at https://github.com/lpowell . The goal of the project was to use command-line switches to control the program, and to provide basic encryption and decryption capabilities, along with rot13 and base64 encoding. First, to load in a key use key, _ = pgpy.PGPKey.from_file(keyfilename) . This loads the key from either a binary or ASCII armored file. You can swap out .from_file for .from_blob , if you plan on using a key stored in a string or bytes object rather than a file. In my example code, I pull the key from a file, as I found it to be the simpler method. Next, you'll need to open a file or create a string or bytes object that contains the message you wish to encrypt. We'll call this file
