Kryptomate vs Kryptodian Cold Signer

Kryptomate is an app to help you en- or decode small text snippets through either Caesar or Vigenère cipher. Be it for a puzzle (e.g. for a Geocache) or for fun with your friends. The caesar cipher is probably the simplest and most well-known cipher out there. It works by shifting each letter of the given phrase forward in the alphabet by a given number. It is named after Julius Caesar, who was known for encrypting sensitive military information with a shift of three. The caesar cipher is often used to teach the basics of cryptography, as it's purpose and function is easily understood. The vigenère cipher works using the same principle, but is significantly younger and it took quite a while for the first person to break it. It uses a key instead of a single shift to determine a different shift for each letter of the given phrase. Doing so makes it a lot harder for a single person to try and break it by guessing the shift. The ciphers used in Kryptomate are in no way something you should use to keep actual data safe. Even the newer of the two methods is over 450 years old. The caesar and vigenère ciphers are both very simple concepts and often used in puzzles. Both are not secure for modern purposes. Please note that Kryptomate will only work with alphabetical characters (A-Z, a-z). Punctuation, numbers and other special characters will stay the same.

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.
