Reviewing the two core files (secrets.c and openpgp.c) will not require
weeks, as they are both about 500 lines of code thanks to the very
good work you've kindly done already with cryptlib.

While static code analysers will work with C code, they might be less
valuable when it comes to reviewing the ksh scripts. These scripts
represent the logic of the message encryption scheme and a review
needs to focus on the security of the ideas, they're based on.

I think I'd add a few rows to my Lotto ticket ;-)
