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.
The project got its initial funding from OWASP in 2007. A secure instant messaging system based on Enigform and HTTPS has been announced during the OWASP Ibero-American Web-Application Security Conference was announced in 2010.
Enigform was granted the Trusted status on the Mozilla Add-ons website in 2008.
On April 23, 2009, Enigform was declared a Finalist in the Security category of Les Trophées du Libre, and was awarded the second prize.
On April 2012, Enigform is now available for testing in the Firefox 12+ series.
Currently, the author has not received the prize money from the Les Trophees du Libre parent company, Cetril, and it seems that the company has vanished.
