Abstract

A system and method for determining export requirements for a content file may include examining a content file to identify content used by or included in the content file that is subject to export control, determining, in response to the identified content, export requirements that are applicable to the content file, and providing an indication of the determined export requirements.

Claims

1. An article of manufacture storing computer readable instructions thereon to examine a software program to identify an encryption algorithm used in the software program, the article of manufacture comprising:

instructions for identifying a first portion of the software program that is similar to a portion of a comparison software program;

instructions for determining that the first portion is associated with an encryption algorithm;

instructions for determining a key length used by the encryption algorithm; and

instructions for providing an indication that the software program uses the identified encryption algorithm.

2. The article of manufacture of claim 1, wherein instructions for determining that the first portion is associated with an algorithm comprises instructions for identifying characteristics of the algorithm.

3. The article of manufacture of claim 1, further comprising:

instructions for identifying a second portion of the software program that is similar to a portion of the comparison software program; and

wherein the instructions for determining that the first portion is associated with an algorithm comprises instructions for determining whether the first portion and the second portion are associated with the same algorithm.

4. The article of manufacture of claim 3, wherein the first portion comprises an interface and the second portion comprises computer code.

5. The article of manufacture of claim 3, wherein the first portion comprises constants associated with the algorithm and the second portion comprises computer code.

6. The article of manufacture of claim 3, wherein the first portion comprises a subroutine call, and the second portion comprises computer code.

7. The article of manufacture of claim 3, wherein the first portion and the second portion are each selected from the group consisting of:

an interface;

computer code;

character strings;

static data; and

a subroutine call.

8. The article of manufacture of claim 3 wherein the indication comprises information for use in completing a document.

9. The article of manufacture of claim 3, wherein the instructions for identifying a first portion of the software program that is similar to a portion of a comparison software program comprises instructions for identifying an interface, computer code, character strings, static data, a subroutine call, or some combination thereof.
