Show HN: I made a zero-knowledge tool to request clients' secrets

I found that many people like myself who run tech companies, agencies, or other types of businesses will often need to ask their clients for various secrets (env files, passwords, access codes, fried chicken recipes...), and there was no tool out there that felt like it was made for that job.

I explored password managers, "one-time link"-type sites, self-hosted, SaaS... none of them had the simplicity I was looking for, for myself and for my clients.

So, I spent my Christmas annual leave building this. keyhold.io is a zero-knowledge custody of secrets platform with a fixed monthly rate, designed not to compete with password managers, but to have alongside a traditional password manager exclusively for client-owned secrets.

Clients can submit secrets into your team's Hold, fully end-to-end encrypted, and they can auto-expire or be deleted on-demand by your client.

This is my first proper go at being a business man/founder/techbro, so I'd love any and all feedback (even if it rips me to shreds). I'm sure I've got a lot of lessons to learn!
