Phasm vs Danmaku Scroll

Hidden in plain sight. Phasm turns ordinary photos into secret messengers. Your photo looks exactly the same — but it carries encrypted messages and files that only someone with the right passphrase can reveal. TWO MODES FOR TWO NEEDS • Ghost Mode — Maximum stealth. Advanced adaptive algorithms make hidden data virtually undetectable, even by statistical analysis tools. Deep Cover auto-activates for non-JPEG photos with ~43% more capacity. Supports file attachments alongside your message. • Armor Mode — Maximum durability. Your hidden message survives recompression, re-encoding, and mild cropping. Fortress sub-mode auto-activates for short messages and handles aggressive compression from popular messaging apps. SERIOUS ENCRYPTION • AES-256-GCM-SIV authenticated encryption — always on, not optional. • Argon2id key derivation — resistant to brute-force and GPU attacks. • Post-quantum safe — 256-bit symmetric keys remain secure against quantum computers. • No backdoors. No key escrow. You hold the only key. PRIVACY BY DESIGN • All processing happens on your device. Nothing is uploaded. • No account. No sign-up. No tracking. No ads. • Open-source Rust cryptographic engine — auditable by anyone. • Built for journalists, researchers, activists, curious tinkerers — or just for fun. ONE PHOTO. MULTIPLE SECRETS. Shadow Messages let you hide several independent messages in a single photo — each locked with its own passphrase. Send the same picture to five friends; each one discovers a different message using their name as the key. Nobody knows the others exist. Under pressure to reveal your passphrase? Hand over the primary one. Your shadow messages stay invisible — no header, no marker, no proof they were ever there. MAGIC WAND — ONE TAP TO OPTIMIZE Tap the wand and your photo is silently tuned for better steganographic embedding. Imperceptible texture is added to smooth regions like skies, bokeh, and flat backgrounds — boosting capacity by 10–35% with no visible change. The photo looks identical. The math works better. SHARE YOUR WAY • Share via AirDrop, Messages, email, or any app that handles images. • phasm.link — generate a short link so recipients can decode instantly in the browser or via App Clip. No install needed. • For guaranteed delivery through messaging apps, use "send as file." BUILT FOR iPHONE AND iPAD • Native app optimized for iPhone and iPad. • Supports JPEG, PNG, GIF, WebP, and HEIC — auto-converted for embedding. • Real-time decode progress with integrity scoring. • 38 languages supported. HONEST ABOUT LIMITATIONS • Platforms that resize or re-encode photos may destroy hidden data. Use direct sharing or "send as file." • Capacity depends on image resolution — larger photos carry more data. • Steganography hides the existence of a message. Encryption protects its content. Phasm gives you both.
