I think the Captcha is part of NSA's profiling plan. One try - born after 1990. Two to five tries - born before 1990. More than five tries - born before 1960.
I can get past it the first time and I was born before 1990.
NSA weakened every single security product made in USA, otherwise they do not give export permission. It include PGP in 1997 with weakened key and 3rd party key, sort of recovery key introduction. What is interesting that even after that happens Tim Zimmerman swears, that there is no backdoor in PGP till I'm here. That gives some clues how much you can trust his current secure phone project.
