{{DISPLAYTITLE:_NSAKEY}}
'''_NSAKEY''' was a [[variable (computer science)|variable]] name discovered in [[Windows NT 4]] [[Windows_NT_4.0#Service_Packs|Service Pack]] 5 (which had been released unstripped of its [[Debug symbol|symbolic debugging]] data) in August 1999 by Andrew D. Fernandes of Cryptonym Corporation. That variable contained a 1024-bit [[public key]].

== Overview ==
[[Microsoft]]'s [[operating system]]s require all [[cryptography]] suites that work with its operating systems to have a [[digital signature]]. Since only Microsoft-approved cryptography suites can be installed or used as a component of Windows it is possible to keep export copies of this operating system (and products with Windows installed) in compliance with the [[Export Administration Regulations]] (EAR), which are enforced by the [[US Department of Commerce]] [[Bureau of Industry and Security]] (BIS).

It was already known that Microsoft used two keys, a primary and a spare, either of which can create valid signatures. Microsoft had failed to remove the debugging symbols in ADVAPI.DLL, a security and encryption driver, when it released Service Pack 5 for [[Windows NT 4.0]] and Andrew Fernandes, chief scientist with Cryptonym of Morrisville, North Carolina found the primary key stored in the variable _KEY and the second key was labeled _NSAKEY.<ref>{{cite web |title=Microsoft, the NSA, and You |publisher=Cryptonym |date=1999-08-31 |url=http://www.cryptonym.com/hottopics/msft-nsa/msft-nsa.html  |accessdate=2007-01-07 |archiveurl = http://web.archive.org/web/20000617094917/http://www.cryptonym.com/hottopics/msft-nsa/msft-nsa.html |archivedate = 17 June 2000}} ([[Internet Archive]] / [[Internet Archive#Wayback Machine|Wayback Machine]])</ref>  Fernan(contracted; show full)
