24 alternatives to Portable Secret – Open-Source HTML files that self-decrypt offline
Hey HN, We've decided to open-source our Portable Secret. It's a free tool that generates self-contained HTML files which decrypt locally in your browser. Check it out at https://alcazarsec.github.io/portable-secret/. Source code: https://github.com/alcazarsec/portable-secret The project is inspired by an old post (https://news.ycombinator.com/item?id=34083366) by mprimi, who coined the term "Portable Secret." I really liked the idea and wanted to improve the security of the KDF and the UX. I hope he's honored that so many people have…

Finally open sourced an internal tool we've been using for managing secrets. It's similar to SOPS, but more opinionated, easier to configure/use correctly, and produces nicer git diffs. It also supports one-way encryption, so you don't have to know the private key to add secrets.

Retriever (https://retriever.corgea.io/), an open-source research project to help users receive secrets and sensitive information without needing a server in the middle. It works by using Public-key cryptography to coordinate the message sharing between the two devices. Read more on why we built it here: https://retriever.corgea.io/why.html

TLDR, Let's Seal gives the finger to Adobe and every doc signing tool (docusign, google, etc) who pay to play with the Adobe Approved Trust List and then charge you for something that should be free. Currently even the person checking if a document/contract is sealed or code is authentic has to also be inside the same Adobe walled garden too. Verification, the part that should be free is the part everyone charges for. Thats the shape Let's Encrypt fixed for TLS, and I wanted the same thing for documents and files. The core idea therefore needed to go a bit beyond e signatures and i…

I have written a passwords/secrets manager for my personal needs. Maybe it solves some of your problems too. It is written in Go and is a self-contained executable for a small web-app: https://github.com/jarmo/secrets-web There is also a CLI version if that is your taste: https://github.com/jarmo/secrets-cli To read about more technical details, look into the core repository at https://github.com/jarmo/secrets Any questions/comments/suggestions are welcome in here or via GitHub pull requests.

On the 40-day anniversary of the Portable Secret Show HN (https://news.ycombinator.com/item?id=34083366), I introduce PrivacyProtect. Portable Secret's mprime1 has little time for upkeep, so, with his blessing, PrivacyProtect picks up where he left off and incorporates the following updates, - Improved security - SHA-512 and 2,100,000 iterations instead of SHA-1 and 1,000,000 - Generate IV and salt at encryption time to prevent reuse - Clear forms on submit - CLI: still WIP, but have a proof of concept working of using NodeJS's WebCrypto APIs to create the HTML files without…

Hey everyone, English is not my native language. This post was polished with AI, but the content is mine. I run a small dev agency in Germany. Every week someone shares database credentials, API keys, or a .env file via Slack or email. Not because they don’t care: because there’s no frictionless alternative. Vault setups are heavy. Enterprise tools are expensive. I just needed: upload → share link → done. But encrypted before leaving the browser. So I built SecretDrop.dev. What it does Files encrypted client-side (AES-256-GCM, PBKDF2 600k iterations) Built entirely on WebCrypto No…

I built SecretMemoryLocker (https://secretmemorylocker.com), a file encryption tool that generates keys dynamically from your answers to personal questions instead of using a static master password. This makes offline brute-force attacks much more difficult. Think of it as a password manager that meets mnemonic seed recovery, but without storing any sensitive keys on disk. Why? I kept losing master passwords and wanted a solution that wasn't tied to a single point of failure. I also wanted to create a "digital legacy" that my family could access only under specific conditions. The…

AxKeyStore▲31Hi HN, I built AxKeyStore, an open-source CLI tool for managing secrets that uses your own private GitHub repository as encrypted storage. The idea is simple: → All encryption happens locally. → Secrets are stored as encrypted blobs in your private repo. → GitHub is treated as untrusted storage. → No plaintext secrets ever leave your machine. → No plaintext secrets are stored on disk. Most secret managers either require a hosted backend, a self-hosted server, or trusting a SaaS provider. I wanted something that: → Requires zero infrastructure → Uses tooling developers already have → Keeps…
