SSH Keys Don’t Scale. SSH Certificates Do.

Most teams traditionally use SSH public key authentication which becomes unscalable with more users and hosts, leading to operational and security risks.
SSH certificate-based authentication offers a more scalable approach and is already used by companies like Meta, Uber, and Google.
SSH key management sprawl, unclear access boundaries, and maintenance challenges arise with traditional SSH key authentication.
SSH certificates enable a centralized, auditable, and secure SSH access model with short-lived credentials.
Setting up SSH certificates requires initial engineering effort but simplifies user access management to hosts.
SSH certificate-based authentication relies on CA-signed certificates for users and hosts, forming a mutual trust model.
Users are configured to trust host certificates, and hosts only allow access to users with valid certificates.
Infisical SSH offers a solution to abstract the complexity of setting up SSH certificate-based access for teams and infrastructure.
Infisical SSH simplifies the setup process by handling CA management, trust configuration, and SSH certificate issuance.
Users can register on Infisical SSH to establish secure SSH certificate-based connections with hosts.

How I Built a TUI Without Leaving the Terminal

TUI, which stands for Terminal User Interface, allows users to interact with software features directly from the terminal using a keyboard-driven approach.
TUI tools are fast, scriptable, lightweight, and favored by developers, sysadmins, and minimalists for their efficiency and simplicity.
The author built a music streaming TUI named Sparklines-TUI on a custom backend built on JioSaavn, leveraging React and Ink for the interactive command-line app.
The tech stack included NodeJS, TypeScript, Ink, mpv for music playback, and custom backend on top of JioSaavn, making it suitable for Termux (Android), though unstable.
The UI development using React and Ink was streamlined, allowing the author to utilize previous web development knowledge with minimal learning curve.
Challenges in the project included implementing music playback with mpv, handling logs, managing custom commands with NodeJS, and working on UI perfection and modularization.
The TUI project features functionalities like controlling music, login/register, API key-based interaction, continuous playback, custom shortcuts, search, recommendations, and more.
A help menu offers useful commands like navigation shortcuts, play/pause, volume control, seeking, speed adjustment, and display options within the TUI.
The author views the project as a personal experiment to push the limits of terminal UI in JS and values the process of learning and experimentation more than external recognition.
The TUI project showcases the potential of leveraging terminal interfaces for personalized applications, emphasizing the importance of self-motivated projects in driving innovation.
This informative article was originally published on https://blog.samay15jan.xyz, delving into the author's journey of building a music streaming TUI within the terminal environment.
