To Whom It May Concern:

This is a request under the Freedom of Information Act. I hereby request the following records:

I request an index of documents from 1970 through 1990 - including name of each document and the date it was produced or published internally - on the Walburn and Saville cryptographic algorithms and/or their use in encrypting telephone communications. Within the index, please include any contracts or communication between the NSA, GCHQ, US Army, NATO, and the company Phillips Usfa (which built encryption devices Spendex-40 and Spendex-50 known as cryptophones).

I also request that, if appropriate, fees be waived as I believe this request is in the public interest. The requested documents will be made available to the general public free of charge as part of the public information service at MuckRock.com, processed by a representative of the news media/press and is made in the process of news gathering and not for commercial usage.

In the event that fees cannot be waived, I would be grateful if you would inform me of the total charges in advance of fulfilling my request. I would prefer the request filled electronically, by e-mail attachment if available or CD-ROM if not.

Thank you in advance for your anticipated cooperation in this matter. I look forward to receiving your response to this request within 20 business days, as the statute requires.
