CryptDrop — Browser-Based File Encryption
OwnStack Digital · March 2026
CryptDrop is a privacy-focused web application that lets users encrypt and decrypt files entirely in their browser. Built with OpenPGP.js, all cryptographic operations happen client-side — files never leave the user's device. Users can generate PGP key pairs, encrypt files for specific recipients, and decrypt received files. The interface is clean and straightforward, making strong encryption accessible to non-technical users.
Project Highlights
- Client-side encryption — files never leave your browser
- OpenPGP standard for interoperable encryption
