ODTC Case: CJ 081-94
YOUR LETTER DATED: March 9, 1994

REQUEST FOR COMMODITY JURISDICTION DETERMINATION FOR: "Applied Cryptography Source Code Disk"

Your commodity jurisdiction (CJ) request was referred to the Departments of Commerce and Defense and the National Security Agency for their review and recommendations. As a result, the Department of State has determined that the subject source code disk is subject to the licensing jurisdiction of the Department of State in accordance with the International Traffic in Arms Regulations (22 CFR 120 through 130). This article is designated as a defense article under category XIII(b)(1) of the United States Munitions List. Licenses issued by this office are required prior to export.

The text files on the subject disk are not an exact representation of what is found in "Applied Cryptography." Each source code listing has been partitioned into its own file and has the capability of being easily compiled into an executable subroutine. The subject disk contains source code listings for each of the following cryptographic algorithms: Vigenere, Beauford, Enigma, DES, Lucifer, NewDES, FEAL-8, FEAL-NX, REDOC III, LOKI 91, IDEA, N-HASH, MD5, Secure Hash Algorithm (SHA), and Secret Sharing. Also, the subject disk contains source code listings for certain algorithms that would not be exportable if they were incorporated into a product.

The intended use of this source code disk, as stated in your CJ request, is to provide code for those who wish to incorporate encryption into their applications. There are fourteen (14) separate source code files that amount to thousands of lines of easily executable code contained on the subject disk. This is certainly an added value to any end-user that wishes to incorporate encryption into a product.

Should you require further assistance on this matter, please contact Tom Denner at (703) 875-7041.

					Sincerely,
