High Quality Content by WIKIPEDIA articles! Enigform is a Mozilla Firefox extension authored by Arturo `Buanzo` Busleiman which uses GnuPG to implement OpenPGP-signed HTTP requests. OpenPGP encryption began to be implemented in 2007. Some people believe it to be an alternative for the Secure Sockets Layer method for encrypting Hypertext Transfer Protocol (or HTTP) connections. However, the author never had such an intention in his mind. Guaranteeing the identity of a requester and the integrity of the request is Enigform`s primary goal, through the use of digital signatures. In this instance, requests are form submissions to web servers. Apache HTTP Server support via the mod_openpgp module currently supports request verification.
