Since this topic is about BSD/OpenBSD I found an interesting article but not sure how credible this is since I didnt do my own research. But do take a look at this very interesting article: http://cryptome.org/2012/01/0032.htm
i know very well this legend to discredit OpenBSD, read this little article on Wikipedia:
http://en.wikipedia.org/wiki/OpenBSD#Alleged_FBI_backdoor_investigatedIt was a FBI's lie to scare the BSD's users, because the system is too secure... and the FBI doesn't like this!!!
Don't worry, BSD is the safest system on the world!!! (even if there isn't the perfect system)
PS: BSD Magazine is not only about OpenBSD but about all the BSD family systems (OpenBSD, FreeBSD, NetBSD, PCBSD, DragonflyBSD, FreeNAS, etc...)
Yeah, there's long been allegations of backdoors in OpenBSD's IPsec stack, among other components, for usage by the FBI. Supposedly a detailed code audit was performed by Theo de Raadt and the OpenBSD team with nothing being found, but I tend to stay away from OpenBSD.
PPS: FreeBSD and NetBSD are better than OpenBSD!!!
