High Security
Apps that make poor choices when implementing tough encryption algorithms can leave your data exposed. We didn’t roll our own, Codebook uses the open-source SQLCipher project and the peer-reviewed OpenSSL implementation of 256-bit AES encryption to store all of your data. This is security you can trust.
