Why I Built a Browser-Based Cryptography Toolkit for Developers

As a developer, I kept running into the same problem: jumping between multiple websites just to handle everyday cryptography and security tasks.

One site for JWT decoding.
Another for AES encryption.
Another for RSA key generation.
Another for bcrypt hashing.

Over time, that workflow became frustrating and inefficient, so I decided to build a single browser-based toolkit focused on speed, simplicity, and developer productivity.

That project became Cipherly: http://cipherlyapp.com/

Current Features
Cipherly currently includes:
• AES encryption/decryption
• RSA utilities
• JWT decoding and inspection
• bcrypt hashing
• Base64 encoding/decoding
• SHA hashing utilities

Why Browser-Based?
A major goal was minimizing unnecessary server-side processing.
With cryptography-related tools, privacy and responsiveness matter.
Running operations directly in the browser helps:
• reduce latency
• improve responsiveness
• minimize unnecessary data transmission
• create a smoother development workflow

Why I Built It
The primary motivation was workflow efficiency.
During authentication, encryption, and debugging tasks, developers often keep multiple utility websites open at the same time. Cipherly aims to centralize those tools into one lightweight and accessible interface.
Looking for Feedback

I’d genuinely appreciate feedback from developers and security engineers on:
• missing tools
• UX improvements
• performance issues
• feature ideas
