OcodX — Encrypt Text & Images

OcodX is a client-side encryption platform that processes all cryptographic operations exclusively within your browser. No unencrypted data is transmitted to any server. ENCRYPTION ENGINE • AES-256-GCM symmetric encryption with PBKDF2 key derivation (100,000 SHA-256 iterations) • Built on the Web Crypto API — no third-party cryptographic libraries • Optional time-limited keys that render ciphertext unrecoverable after expiration • Keyless Mode applies Base64 obfuscation for low-sensitivity content • Password strength evaluation powered by Have I Been Pwned breach database lookups TEXT ENCRYPTION • Encrypt and decrypt text messages using a shared password • Output is a portable ciphertext string that can be copied and shared through any channel • Five free daily operations; additional operations available via credits or subscription • Works fully offline after installation IMAGE ENCRYPTION • Select or capture an image, encrypt it with a password, and receive a 6-character sharing code • Recipients enter the code and password to decrypt and view the original image • Encrypted images are stored with configurable expiration (1 hour to 7 days) • Automatic cleanup removes expired data EPHEMERAL ROOMS • Create or join real-time encrypted chat rooms using a 6-character room code • All message history is permanently deleted when the last participant leaves • Room creators can lock rooms to prevent new participants from joining • Creator moderation tools: remove participants and report users • Rooms automatically expire after 24 hours • Each participant is assigned a random color identifier — no usernames or personal data CREDIT ECONOMY • Earn credits by completing brain-training games: — Memory Challenge: match pairs of cards across 7 difficulty levels — Symbol Match: catch falling symbols matching a target set within 45 seconds — Flash Number: memorize and reproduce number sequences of increasing length • Credits fund premium operations: text encryption (2 credits), image encryption (5 credits), image decryption (3 credits), room creation (10 credits) • Game progress resets daily, providing a renewable credit source • Optional subscription removes all credit requirements (soon ). PRIVACY ARCHITECTURE • Zero-knowledge design: the server never receives passwords, keys, or plaintext • No analytics, tracking pixels, or advertising SDKs • No user profiles, friend lists, or social graphs • Blocked user lists and preferences stored locally on your device • Content moderation operates entirely client-side • Account deletion permanently removes all server-side data Built for users who require verifiable, transparent encryption without account-based data collection.
