Cipher Pixel vs Phasm

Cipher Pixel: Hide Messages in Your Photos With Cipher Pixel, you can securely send hidden messages or keep them safely hidden within images in your gallery. Cipher Pixel makes it easy to hide secret messages in your photos. Using the ancient technique of steganography, this app conceals information within the pixels of your images. Unlike cryptography, which scrambles data into unreadable text, steganography hides data in plain sight, ensuring secrecy without drawing attention. Why Choose Cipher Pixel? Seamless Integration: Effortlessly hide messages in your photos without changing their appearance. User-Friendly Design: Encode and decode messages with ease using a simple interface. Advanced Security: Encrypt your secret messages using the AES algorithm before embedding them in your photos, ensuring that your hidden data is protected with an extra layer of security. How It Works: Encode: Input your message, and Cipher Pixel transforms it into bits. Encrypt: Secure your message with AES encryption before hiding it in the image. Embed: Select a photo, and let Cipher Pixel discreetly hide your encrypted message within its pixels. Share Securely: Share your photo confidently, knowing your hidden message is safe. Additional Note: Once you have created an image with a secret message hidden in the Cipher Pixel app, be careful not to resize or compress the image when sharing it. When sending an image using messaging applications, the image must be sent as a 'Document'. If you send it as an image, the saved message may be lost. This is because messaging applications change the image format.

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.
