About JWTSecrets

A free, open, client-side toolkit for JWTs and the cryptography around them — built by developers, for developers, with nothing sent to a server, ever.

Our story

JWTSecrets started the way most useful developer tools do: out of friction. Generating a secure JWT secret, checking a key's entropy, or decoding a token mid-debug shouldn't mean pasting sensitive key material into some rando website and hoping for the best. So we built the tool we wanted to exist — one that runs entirely in your browser using the Web Crypto API, with the source and logic fully inspectable, and nothing about your keys or tokens ever leaving your machine.

The team behind JWTSecrets is also the team behind arcloops.ai — we spend our working hours helping companies think clearly about AI: auditing where it actually fits, training teams to use it well, and building AI-driven consulting and solutions work, mostly for enterprises across Bangladesh and increasingly the UAE. JWTSecrets isn't an arcloops.ai product line — it's something separate we maintain because we're engineers and security-minded people first, and we think the same instinct that makes good consulting work — being precise, being honest about tradeoffs, not overcomplicating things — applies just as well to a free tool for the developer community.

What we believe

Privacy isn't a feature, it's the default.

Every generator, encoder, and validator on this site runs client-side. We don't want your secrets, so we never see them.

Good tools explain themselves.

Alongside the tools, we write real guides — not filler — on how JWTs, key generation, and secure secret storage actually work, because we'd rather you understand what you're generating than just click a button and hope.

Free means free.

No account, no paywall, no “sign up to copy your key.” If we ever build something that needs a business model, that’ll be a separate, clearly labeled product — not a bait-and-switch on the free tools.

Behind the tools

We're based in Bangladesh, and building for a global developer audience — the same instinct driving arcloops.ai's work with enterprises here and in the UAE also shows up here: be grounded, be precise, and build things that hold up under real use rather than just looking good in a demo.

We're actively expanding what JWTSecrets offers — more cryptographic tools, deeper guides, and (down the line) some enterprise-focused features like key rotation APIs and JWT lifecycle tooling for production teams. If there's a tool or guide you wish existed, tell us — most of what's here started as exactly that kind of request, even when the request was our own.
