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.
