DieFi uses the strongest encryption algorithms and techniques available, combined with Blockchain and AI technologies. Our FIPS 140-2 compliant end-to-end encryption design ensures that only you have access to your data and no one else — not even FortKnoxster can access any data. In fact, the only thing we can see is your email address used for signing up. The DieFi cryptography consists of AES-GCM 256-bit symmetric encryption, RSA-OAEP/RSA-PSS 4096-bit encryption with SHA-512, and Elliptic Curve ECDH/ECDSA P-521 encryption.
The decentralized Dead Man’s Switch feature consists of strong end-to-end encryption combined with a decentralized Key Management System (KMS) approach. DMS is using proxy re-encryption for secret key sharing with timed-based policy encryption through blockchain smart contracts on the Polygon Blockchain.
DieFi consists of various decentralized components, such as decentralized storage, blockchain technology, and decentralized KMS to protect time-based encrypted data with proxy re-encryption (PRE).

DieFi uses a zero-knowledge authentication scheme in which the user’s password never leaves the user’s device, keeping you in control of your private keys and confidential security information. FortKnoxster never transmits or stores passwords in plain text, as these are protected with hash-based encryption for zero-knowledge authentication.
FIPS 140-2 is a mandatory standard for the protection of sensitive or valuable data at government and military level systems. FortKnoxster uses FIPS 140-2 compliant encryption for securing customer data and communication at rest and in transit, with hardware security modules (HSM).
FortKnoxster has developed a unique peer-to-peer encryption protocol between users’ client devices and DieFi crypto nodes to protect against MITM attacks and prevent unauthorized account access beside the TLS layer. All critical user actions, such as fetching contacts and their public keys, account synchronization, and user settings (like account recovery, password change, and two-factor authentication), are both encrypted and cryptographically signed bidirectionally between the user device and the crypto nodes.
Our source codes are open-sourced on GitHub and allow security researchers to fully evaluate the DieFi end-to-end encryption implementation and security.
All DieFi related smart contracts have all been security audited prior to deployment on the Ethereum and Polygon Blockchains.
We are looking forward to working with the security community in order to keep our app as safe as possible. If you are a security-researcher, white-hat hacker or developer and want to report a vulnerability, please visit our contact page.
