Cert Decoder

NotionLock

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

NotionLock appears to be a niche utility tool designed to add password protection to Notion pages, which is useful since Notion doesn't natively offer granular password protection for shared pages. It's a good solution if you need a lightweight way to restrict access to specific Notion content without building custom authentication systems.

Why this product is good

Fills a genuine gap since Notion lacks native password protection for individual shared pages
Simple setup process that doesn't require technical or coding knowledge
Affordable alternative to building custom access control systems
Useful for protecting sensitive content like client portals, internal docs, or paid content shared via Notion

Recommended for

Freelancers and consultants sharing client-specific Notion pages
Creators selling gated content or digital products via Notion
Small teams needing basic access control without upgrading to enterprise Notion plans
Educators or coaches sharing course materials with paying students
Anyone needing a quick, no-code password layer for public Notion links

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
