PGPMenu Implementation Issues and Decisions

Derek Atkins

The major goal of PGPMenu was to make it easy to implement, easy to modify, and easy to use. This brought about the concept of using some script language for the implementation. I also thought about the security of the system, and decided that using a graphical language, like tcl, would make it difficult to destroy the user passphrase on request. As a result, I chose to implement PGPMenu in PERL, and allow PGP to grag the passphrase itself. Another choice could have been to write a special C program that would integrate with a TCL script to grab the password securely and stuff it into PGP, but I decided that I didn't have enough knowledge of X programming to do that well.
