Have you ever wanted to hide a secret message inside a photo? With Steganography, you can encode a message or image in a picture and then save it or send it to a friend. The message can only be decoded using the same app, but if you want to ensure that only the intended receiver can read the message. Steganography is the best steganographic app available for iOS. Send messages and images without anyone knowing. Steganography is the practice of hiding data in plain sight. Pictograph works by changing the least significant bits in each pixel in a specific way so that a message can be hidden. Because Pictograph only changes the least significant bits in a pixel, the change is imperceptible to human eyes. Steganography Premium plans with No commitment. Cancel anytime.

About

Sesam

Sesam protects what is yours: your messages, your photos, your papers, your passwords, your crypto. Everything is encrypted on your phone. Nothing leaves for a server — there is none. MESSAGES NO ONE ELSE CAN READ Write your message: Sesam turns it into an unreadable block. Send it anywhere — SMS, WhatsApp, email, it doesn't matter. Only the person who holds your key can read it. That key was exchanged in person, by scanning a QR code. It never went through the internet: there is nothing to intercept. Photos and videos included. And the Sesam keyboard encrypts what you type without leaving the app you're in. A KEY YOU CONTROL A safety number, compared out loud, confirms no one slipped in between you. One key can bring a group together — and be replaced when someone leaves. In doubt? Renew it in one gesture; the old one stops working instantly. THE MESSAGE THAT DOESN'T LOOK LIKE A MESSAGE Your encrypted message can hide inside an ordinary conversation you write yourself. On screen, everyday sentences. The secret travels between the letters, invisible. A TRUE COLD WALLET Bitcoin, Litecoin, Ethereum and EVM networks — Polygon, Base, Arbitrum, Optimism, BNB Chain, Avalanche. The key is born on your phone and never leaves it. Receiving needs no connection: the chain records. To send, paste the transaction prepared on a connected device: Sesam shows it IN THE CLEAR — network, recipient, amount, maximum debit — and signs only after Face ID, offline. No more blind signing. Your balance? A watch-only export to scan in a connected app: it sees everything, can spend nothing. And your 24 words stay encrypted in the vault, checked as you type — a copy error shows immediately, not the day it's too late. A SAFE IN YOUR POCKET Photos, videos, documents, notes, passwords: everything behind your code. Your credentials live in masked cards, copied to a clipboard that erases itself. A scanner straightens your papers without touching the photo roll. And from any app: Share, then Sesam — encrypted, filed, and the original can disappear for good. NO ONE KNOWS SESAM EXISTS Sesam can take the appearance of another app — about fifteen disguises, with the real icon and the real interface. Which ones? That's exactly what we don't say. A second code opens a decoy vault, filled with conversations you wrote yourself. A third erases everything. FOR THE HARD MOMENTS Before a border, travel mode takes the key out of the phone: your files remain, but become unreadable. The access log tells you who tried to open, and when — with their photo if you wish. Too many failures, or too many days without opening: everything is erased. NOTHING IS EVER LOST Twenty-four words, written on paper, are enough to recover everything on a new phone — and only they can. A printable sheet keeps them safe from a breakdown. A sealed archive under a secret phrase carries everything — without a server. ON YOUR WRIST, AND ON YOUR MAC Read a message on Apple Watch, iPhone still in your pocket. On the Mac, Sesam waits in the menu bar and encrypts what you just copied. DON'T TRUST US. VERIFY. Switch to airplane mode: everything still works. Then open Settings, Privacy, App Privacy Report: iOS records every connection of every app there. Next to Sesam, the list stays empty. That's not a promise. It's a record kept by your own phone. FOR EXPERTS • Cascade AES-256-GCM then XChaCha20-Poly1305, two authenticated layers • Argon2id, 64 MB per attempt — beyond OWASP recommendations • Wallet: BIP-39/32/44/84, PSBT, EIP-1559 — verified against reference implementations • No account, no server, no usage analytics
