    Novel Insight Inner Circle

    Novel Insight Inner Circle

    Graphical message and file encryption tool

    ...The encryption uses AES-256 twice so it is harder to crack than the industry standard pure AES 256bit implementation (theoretical key size is 512 bit). The software writes encrypted data in ASCII text format which can be cut'n'pasted to messaging apps or to emails and back to Inner Circle when decrypting data. IMPORTANT: The software requires new OpenJDK 16 (Not Oracle's J2RE 1.8) to run. Install, for example, AdoptOpenJDK for Windows. NOTE: By using encryption twice the implementation is (in theory) vulnerable to Meet-In-The-Middle attack reducing key size to 256bit but the attack still requires 2^256 bytes of memory making it impossible in practice.

    Key Transparency

    Key Transparency

    A transparent and secure way to look up public keys

    ...The architecture separates operators from verifiers: even if the service is compromised, independent clients can audit inclusion and consistency proofs to maintain trust. APIs and reference components demonstrate how account lookup, update, and auditing flows fit together for messaging or identity systems. By making key state globally visible and tamper-evident, the project reduces the need to blindly trust a single directory operator. It serves as a blueprint for building end-to-end encryption ecosystems that remain transparent and accountable at Internet scale.
