Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Asynchronous File Compression/Decompression with Encryption/Decyption using AES-256(CBC) based Encryption.

Gets the input stream from the file supplied as args. (This is piped to the cipher) Encypts the file using AES-256(CBC) 256-bit based Encryption. (This is piped to Zlib's Gzip/Gunzip) Makes use of node's zlib module to perform Gzip compression/decompressions. After chaining up the streams successfully, the content is then piped to the transform stream which then prints out every chunk of data it receives (Encrypted/Decrypted).

Output of the Compression process is going to be a .gz file with Encypted Content. Thereby, making it invulnerable to bruteforcing attacks since every individual file is compressed rather than the zip itself.

Dependencies are through2-map to make use of transform streams to print to stdout while chaining up the pipes. Installation: npm install through2-map --save

Usage:

  1. File Compression with Encyption: node index.js <ABSOLUTE_FILE_PATH> C <ENCRYPTION_KEY>

Eg: node index.js ./test.txt C testpassword123

  1. File Decompression with Decryption: node index.js <ABSOLUTE_FILE_PATH> D <DECRYPTION_KEY>

Eg: node index.js ./test.txtCompressed.gz D testpassword123
