In [[cryptography]], '''format-transforming encryption''' (FTE) refers to encryption where the format of the input plaintext and output ciphertext are configurable. Descriptions of formats can vary, but are typically compact set descriptors, such as a [[regular expression]].<ref>{{cite book |date=November 2013 |pages=61–72 |doi=10.1145/2508859.2516657 |chapter-url=https://eprint.iacr.org/2012/494.pdf |language=EN |author1=Kevin P.

Format-transforming encryption is closely related to, and a generalization of, [[format-preserving encryption]].

FTE is used by the Tor Project to circumvent [[deep packet inspection]] by pretending to be some other protocols.<ref name="Tor Project: Pluggable Transports">{{cite web|title=Tor Project: Pluggable Transports |url=https://www.torproject.org/docs/pluggable-transports.html.en |work=torproject.org |accessdate=2016-08-05}}</ref> The implementation is {{tt|fteproxy}}; it was written by the authors who came up with the FTE concept.<ref>{{cite web |last1=Dyer |first1=Kevin P. |title=kpdyer/fteproxy |website=[[GitHub]] |url=https://github.com/kpdyer/fteproxy |date=27 February 2020}}</ref>
