I just wanted to build something simple with Rust and this idea just popped into my mind. I explored some other CLIs written in Rust, understood the working and then decided to make Secli as a part of learning. Few days into building, I realised that this can potentially have a large user base so I decided to make a logo and banner and also launch it on Producthunt :)
You can see how to use Secli in the project's README
