Haskell Implementation of the RNCryptor spec

This library implements the specification for the RNCryptor encrypted file format by Rob Napier.

Current Supported Versions

• V3 - Spec

Requirements

The library uses by default a fast C layer to compute the PBKDF2, but that requires the presence of the OpenSSL libraries on the target system. In case this is a too rigid requirement, you can switch back to a pure (slower) Haskell implementation by turning off the fastpbkdf2 cabal flag.

TODO

• Key-based test vectors
• Key-derivation test vectors

Contributors (Sorted by name)

• Alfredo Di Napoli (creator and maintainer)
• Rob Napier (gave me the key insight to use the previous cipher text as IV for the new block)
• Tim Docker (Added decryptEither and gave us momentum in turning decrypt into a total function)
• Tom Titchener (added support for HMAC validation)
