About

Kryptodian Cold Signer

Read full description

Kryptodian Cold Signer is a companion app designed to work with the Kryptodian web application. The app securely generates a cryptographic keypair using the Secure Enclave on the device for the organization’s Admin. It leverages the private key to sign requests initiated from the Kryptodian website, ensuring secure and authenticated communication. The signed requests are then sent back to the Kryptodian API, allowing the Admin to approve or reject actions directly from their device. We are adding an extra layer of security for the Admin of an organization that manages significant cryptocurrency balances. Many critical requests initiated within the organization require verification and approval from the Admin. To enhance the security of these approvals, we chose to build this application specifically for Apple devices, leveraging the Secure Enclave and the trusted security features provided by Apple hardware and iOS.

Password managers ask you to trust them with everything. One breach β€” and your whole digital life is exposed. Cipher works differently: you store hints, not passwords. The passwords stay in your head. HOW IT WORKS Keep two or three base patterns in your head. They are never written down anywhere. For each service, save only a hint about which pattern and which rule you used: "Bank β€” pattern B, caps, +2024" That hint is useless to anyone else. The password itself never leaves your head. WHAT YOU GET - Hints, notes and text files encrypted with AES, each protected by a passphrase you choose - Passphrases are never stored β€” not on the device, not in the cloud - Works fully offline, no account required - Optional cloud sync with your Apple or Google account, if you want your hints on every device - Import text files, search across your encrypted items - Also fits crypto seed-phrase hints and any private note WHO IT IS FOR People who do not want to hand every password to a single vault. If you have hundreds of random passwords, a password manager is the right tool. If you rely on patterns in your head and keep forgetting which rule you used where, Cipher is for you.
