The framework contains three components:
LowParse: At the core of EverParse is LowParse, a verified library of parsing and formatting combinators programmed and verified in F*.
3D: A frontend for EverParse to enable specifying data formats in an style resembling type definitions in the C programming language. We have used it to generate message validation code for use within several low-level C programs.
QuackyDucky: A frontend for EverParse that accepts data formats in a style common to many RFCs. We have used it to generate message processing code for several networking protocols, including TLS and QUIC.
