NoiseCrypt encrypts a file into a .ncry container and can turn that container into an ordinary video file, so it survives being uploaded to a platform that re-encodes everything it is given. Download the video later and the original file comes back.
Encryption is hybrid post-quantum: X25519 combined with ML-KEM-768, both secrets folded into a single key-derivation transcript, so the result holds as long as either one does. Content is sealed in chunks rather than under one authentication tag, and the video layer carries two levels of error correction with a checksum per frame, because a re-encoded video is a channel that damages data in two unrelated ways.
This is encryption, not steganography. It offers no deniability: a NoiseCrypt video looks exactly like what it is.
Right-click any file to encrypt it or decrypt it, or use the graphical interface, which opens in your browser and is served by the program itself on this machine only. The installer is per-user by default and needs no administrator rights. FFmpeg is required only for the video commands; all the encryption works with nothing else installed. NoiseCrypt has no account, no server and no telemetry.
What's new in 0.7.2
No change to the program since 0.7.0: 0.7.1 and 0.7.2 only update the build pipeline and the website. 0.7.0 added right-click decryption of an encrypted file directly from Explorer, and right-click encryption of any other file to this machine's own identity instead of a passphrase.
