Show HN: FileVeil · Hide Any File Inside Another File
FileVeil is a browser-based tool that lets users hide any file inside another file—such as a photo, video, or document—so the cover file remains functional while containing AES-256-GCM-encrypted hidden data. Everything runs locally without uploads or servers.
Background
FileVeil is a browser-based steganography tool — it lets you conceal one file (encrypted) inside another ordinary-looking file, like a photo or video. The result appears to be a normal file and functions normally, but actually contains hidden data.
