About

DCT is a cryptographic identity and data protection extension designed to secure user-controlled data through strong, policy-bound cryptography. Its primary purpose is to manage cryptographic keys and apply protection to data before it is sent, stored, or verified.

DCT does not replace applications or services. Instead, it adds a security layer by using a single cryptographic identity to protect data across different environments while keeping full control in the user’s hands.

The same cryptographic identity used to protect messages and files can also be used to control digital assets on supported networks. Assets are linked directly to identity keys, balances are shown for reference only, and every action requires explicit user approval. Asset support exists strictly as part of identity ownership and protection, not as a trading or financial service.

To enforce security and policy integrity, DCT uses a two-part key architecture. A local key (K1) is derived from the user’s private key and never leaves the device. A second key component (K2) is derived only after policy verification. The final protection key is generated by combining both components:

Master Key = K1 + K2

Policies are verified before protection is applied and contribute to key derivation in a way that prevents bypass or tampering. Any modification to a policy results in decryption failure, and only valid, verified policies can unlock protected data. All cryptographic operations remain strictly bound to the user’s identity.

Using a single cryptographic identity, DCT can protect messages before they are sent, email content before sending, files before upload or storage, digital assets linked to the identity, and web data that requires identity verification. Protection is always applied before data leaves the user’s device.

DCT does not manage inboxes or social feeds, does not read or analyse user data, does not trade or sell assets, and does not replace messaging, email, or cloud services. Its role is limited to cryptographic protection and identity verification only.

By combining identity-based key management with policy-bound protection, DCT provides a clear and focused security model. Users retain full control over their keys and actions while applying consistent protection across data and assets without bundling unrelated functionality.
