## Description

crypt.fyi lets you share sensitive information securely. The service encrypts secrets in your browser using ML-KEM post-quantum cryptography before they ever reach the server, so the operator never sees plaintext or keys. Secrets can be set to burn after a single read, after a number of failed attempts, or when a time-to-live expires. Optional password protection, file uploads, IP allow-lists, read limits, and webhook notifications are built in. A CLI and Chrome extension provide alternative ways to create and retrieve secrets. The stack runs as an API server, a static web front end served by nginx, and Redis for ephemeral storage. You can deploy it yourself with Docker Compose or the provided Railway template.
