Phasm

Hiding a message is easy. Surviving a chat app's #recompression isn't. Phasm's Armor mode survives WhatsApp's standard pipeline end-to-end. #Stego Verified. The receiving side only needs the passphrase. Insta, Snap, WeChat still destroy it. Working on it. phasm.link/fwpnPeGg

shadow passphrase it "Plausible" - I you wanna try…

Phasm has a mode called #ShadowMessages. One photo. Independent messages. Each locked with its own passphrase. If you're forced to unlock it, you give up one. The shadows leave no no statistical trace they were ever there. #PlausibleDeniability! #Stego phasm.link/rsrh0RSs

@cgaffga The password is "Plausible" :)

@PhasmStego But where is the shadow message?!? I don’t get it

#Encryption protects the *contents*. #Steganography hides the *existence* of a message. A border guard who finds a Signal App has a question to ask. Scrolling a camera roll of street photos doesn't. That's the threat model that matters in some places. phasm.link/rWO20FFz

Built on three things nobody's combined before: • Pure-Rust JPEG coefficient codec, Open Source • J-UNIWARD + syndrome-trellis coding (Ghost mode, stealth-first) • STDM + Reed-Solomon + Fortress sub-mode — the only stego we know of that survives WhatsApp
