Format-Transforming Encryption Library/Toolkit

LibFTE is the first general-purpose library that introduces a unifying framework for general-purpose development and deployment of FPE or FTE schemes using formats specified by regular expressions. LibFTE also overcomes some technical limitations of the prior FTE software.

Previously, ranking was performed using the Deterministic Finite Automata DFA representation of regular expressions, which means that format-abiding encryption was feasible only for regular expressions for which the DFA representation could be built.
