Encrypt files & Hide encrypted data

A privacy-focused steganography toolkit that helps you hide encrypted messages inside everyday images and audio without raising eyebrows.

Privacy-first notepad: Argon2id + AES-256-GCM, hidden-volume plausible deniability (N notebooks per URL), optimistic concurrency, dead-man's switch, drand/tlock time-locked notes, and one-shot encrypted send. Next.js frontend, Firebase Functions, auditable Firestore rules. MIT.

Hide any data in any file. Steganography tool that never modifies the carrier - transmits only encrypted positions. X25519 + ChaCha20 with forward secrecy.

Encrypt and decrypt your data securely using custom security questions — with all processing handled entirely offline

Secure Optical Air-Gap File Transfer via QR-Code GIFs Hiss secrets into yarn balls 😼 — cat-meme QR GIFs built for camera loss (fountain codes) and fail-closed crypto.

False Bottom Encryption constructs a symmetric scheme (in the sense of using the same key to encrypt and decrypt) that shares the properties of both honey encryption and deniable encryption.

Tool to encrypt and hide files in other files

We introduce the notion of oblivious secret sharing as an enhancement of (conventional) secret sharing with the added possibility of (plausibly) denying that some shares even exist.
