What type of encryption does PicSafe use?

Other FAQs

PicSafe uses RNCryptor for all encryption. RNCryptor is a cross-language AES Encrypter/Decrypter data format.

The data format includes all the metadata required to securely implement AES encryption, as described in "Properly encrypting with AES with CommonCrypto," and iOS 6 Programming Pushing the Limits, Chapter 15. Specifically, it includes:

  • AES-256 encryption
  • CBC mode
  • Password stretching with PBKDF2
  • Password salting
  • Random IV
  • Encrypt-then-hash HMAC

The broad support of this format makes it easier for hospitals and institutions to integrate PicSafe into their medical record systems. There are implementations of RNCryptor in Swift, Objective-C, C, C++, C#, Erlang, Go, Haskell, Java, PHP, Python, Javascript, and Ruby.
