In an e-mail sent to BSD project leader Theo de Raadt, former NETSEC CTO Gregory Perry has claimed that NETSEC developers helped the FBI plant "a number of backdoors" in the OpenBSD cryptographic framework approximately a decade ago.

Perry says that his nondisclosure agreement with the FBI has expired, allowing him to finally bring the issue to the attention of OpenBSD developers. Perry also suggests that knowledge of the FBI's backdoors played a role in DARPA's decision to withdraw millions of dollars of grant funding from OpenBSD in 2003.

The e-mail became public when de Raadt forwarded it to the OpenBSD mailing list on Tuesday, with the intention of encouraging concerned parties to conduct code audits. To avoid entanglement in the alleged conspiracy, de Raadt says that he won't be pursuing the matter himself. Several developers have begun the process of auditing the OpenBSD IPSEC stack in order to determine if Perry's claims are true.
