Cert Decoder
SecretDrop.dev

Cert Decoder is a free online tool that helps you decode X.509 SSL/TLS certificates in PEM format. It instantly shows important information like the issuer, expiry date, SAN entries, and fingerprint. All data is processed locally in your browser, so nothing is ever sent or stored elsewhere.

SecretDrop is a zero-knowledge secret sharing tool for developers. Files are encrypted in the browser using AES-256-GCM before they ever reach the server. The server stores only encrypted blobs and can never read your content, filenames, or passwords. Upload files, set a password, share a link....

SecretDrop.dev

Overall verdict

  • Cert Decoder appears to be a free online tool for decoding and inspecting SSL/TLS certificates, CSRs, and related cryptographic data, making it useful for quick, no-install certificate analysis, though it should be used with awareness of general web tool privacy considerations when handling sensitive certificate data.

Why this product is good

  • Provides quick, browser-based decoding of certificates without needing to install software
  • Useful for troubleshooting SSL/TLS certificate issues on the fly
  • Simple interface aimed at both technical and semi-technical users
  • No cost to use for basic certificate decoding tasks

Recommended for

  • System administrators needing to quickly verify certificate details
  • Developers debugging SSL/TLS configuration issues
  • IT support staff troubleshooting website certificate errors
  • Students or professionals learning about certificate structure and encoding

Overall verdict

  • SecretDrop.dev appears to be a niche utility for securely sharing sensitive text or secrets via a self-destructing, one-time link, offering a simple and useful solution for temporary secure sharing rather than a full-featured product with broad ratings or reviews available.

Why this product is good

  • Enables sharing sensitive information without leaving it in chat logs or emails
  • Typically employs one-time-view links or expiration timers to reduce exposure risk
  • Simple, lightweight interface focused specifically on secure secret sharing
  • Reduces risk of sensitive data lingering in inboxes or messaging platforms
  • Free or low-cost tools of this type are generally easy to adopt for quick use cases

Recommended for

  • Developers needing to share API keys, tokens, or passwords temporarily
  • Teams wanting a quick way to send credentials without permanent storage
  • IT support staff sharing one-time credentials with clients or colleagues
  • Anyone needing a simple, ephemeral method to transmit sensitive text
  • Users who want an alternative to pasting secrets into chat or email

Questions & Answers

As answered by people managing Cert Decoder and SecretDrop.dev.

What's the story behind your product?

Cert Decoder's answer

I built certdecoder.com over the weekend for my own needs. Sometimes in my work, I need to verify and check certificate details.

SecretDrop.dev's answer:

Built by a dev agency founder in Germany who got tired of watching teammates share database credentials and API keys over Slack every week. Not because they didn't care about security — because there was no frictionless alternative. SecretDrop was built to fill that gap.

Which are the primary technologies used for building your product?

Cert Decoder's answer

certdecoder.com was built using just JavaScript and HTML—simple, fast, and with all processing happening locally in your browser, so no certificate data is sent to any server

SecretDrop.dev's answer:

React 19, Vite 6, Tailwind CSS 4, and shadcn/ui on the frontend. NestJS 11 with TypeScript on the backend. Astro 5 for the landing page. Supabase for auth, database, and storage. Web Crypto API (AES-256-GCM, PBKDF2) for all encryption. Polar for billing.

How would you describe the primary audience of your product?

Cert Decoder's answer

certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.

SecretDrop.dev's answer:

Developers, freelancers, and small dev teams who need to share API keys, .env files, and credentials quickly and securely without spinning up a Vault instance or paying for enterprise tooling.

Why should a person choose your product over its competitors?

Cert Decoder's answer

Simple, fast, and reliable. Some similar tools can’t even decode basic certificates. I rigorously tested my tool with many real-world certificates and covered several edge cases where competitors fall short.

SecretDrop.dev's answer:

The real competitor is "paste it in Slack." Vault is heavy, enterprise tools are expensive and require setup. SecretDrop gives you zero-setup, encrypted-by-default sharing with a free tier — no accounts for recipients, no credit card, no infrastructure to manage.

Who are some of the biggest customers of your product?

Cert Decoder's answer

certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.

SecretDrop.dev's answer:

SecretDrop is an early-stage product — there's no public customer list to share. It's built for and used by indie developers, freelancers, and small agencies.

What makes your product unique?

SecretDrop.dev's answer:

True zero-knowledge encryption that happens entirely in the browser using only the Web Crypto API — no third-party crypto libraries, no server-side access to your data. It's as simple as upload, set password, share link — but with enterprise-grade cryptography underneath.

  • Banana.dog back from the dead
    Why? Because I built certdecoder.com and couldn’t find a decent place to submit it. So I said screw it — I’ll build my own. With blackjack and hookers. - Source: dev.to / over 1 year ago
