Filescrypt

Utilities

$3.99

Encrypt files, photos, messages, scan, audio and videos, and sign your PDFs with a key that can't be stolen, locked by Face ID. Resistant even to quantum computers. The vault even you can't force open. What if the only key capable of unlocking your most sensitive files literally existed nowhere — except inside a chip that can never be extracted from your own iPhone, iPad or Mac? That's exactly what Filescrypt does: an all-in-one that protects your files and photos as well as your most sensitive messages — and signs your PDF documents. A KEY THAT NEVER LEAVES YOUR DEVICE Filescrypt doesn't lock your files with a password someone could guess, steal or crack. Your classical private key is generated and locked inside the Secure Enclave — the dedicated chip that protects banking and biometric data on Apple devices. It can never be extracted, not even by you. Your post-quantum key is protected by the device's encrypted keychain and your biometrics. STATE-OF-THE-ART ENCRYPTION, RESISTANT EVEN TO QUANTUM COMPUTERS Hybrid scheme: ECDH P-256 + ML-KEM-768 + AES-256-GCM — at the cutting edge of what exists today. It's the approach adopted by the most advanced encrypted messaging systems: combining classical and post-quantum cryptography, so an attacker would have to break both sides to read anything. FACE ID OR TOUCH ID: YOU ARE THE KEY Forget passwords. A glance or a fingerprint is all it takes to decrypt. An optional auto-lock asks for authentication again every time you return to the app, like banking applications. FILES, PHOTOS, MESSAGES, SCAN, AUDIO, VIDEOS Encrypt any file, one photo and video or several at once — they're then bundled into a single archive. You can also type a message directly in the app, or dictate it, then encrypt it with one tap: the result can be copied or emailed without ever creating a file. PDF DOCUMENT SIGNING Sign a PDF with the same hybrid post-quantum security, and apply a visual stamp — name, place, date and key identifier — exactly where you choose by tapping the document. A preview shows its actual size before you confirm, and the stamp is fused into the page: it can't be selected or erased in a PDF reader. Add your company logo if you wish. Hybrid post-quantum digital signature, with no certification authority: authenticity is verified by comparing key fingerprints directly between the parties. SEVERAL SIGNERS, IN ORDER Set the number of signers at the first signature, then pass the document around: each person adds theirs wherever they choose. Each signature cryptographically commits the ones before it — nobody can be inserted, removed, or sign twice. VERIFY A DOCUMENT YOU RECEIVE Simply open the PDF in the app: it confirms that the signatures are authentic, that the chain is intact and that the text is unchanged since signing, then lists the details of each signer. SECURE SHARING BETWEEN USERS Exchange your public key with anyone you choose — attachment, copy-paste or email — and encrypt documents meant only for that person. Only the holder of the matching private key will be able to open them. A short identifier shown for each key lets you confirm out loud that the key received is the right one. AT A GLANCE - Private key that is physically non-extractable (Secure Enclave) - Hybrid post-quantum encryption (ECDH P-256 + ML-KEM-768 + AES-256-GCM) - Unlock with Face ID / Touch ID, optional auto-lock - Encryption of files, batches of photos and messages - PDF signing with an indelible stamp and authenticity verification - Multi-signer support, in a tamper-proof order - Secure multi-user sharing via public key - Bilingual interface: French / English - iPhone, iPad No account, no server, no data in transit: everything happens on your device. Filescrypt: because the best key is one that exists nowhere to be stolen.
