That was just a naming convention. When asked why it was called NSAKEY, Microsoft said this: >This is simply an unfortunate name. The NSA performs the technical review for all US cryptographic export requests. The keys in question are the ones that allow us to ensure compliance with the NSA's technical review. Therefore, they came to be known within Microsoft as "the NSA keys", and this was used as a variable name for one of the keys. However, Microsoft holds these keys and does not share them with anyone, including the NSA.
