vList Xtra VLIST XTRA HELP: EXPORT OF AES ENCRYPTION  
 

Tabuleiro is a Brazilian company and not subjected to restrictions in the sale and export of products capable of strong encryption. However, many countries including the United States restrict the export of products that contain strong encryption. The US export restrictions were relaxed quite a bit in fall 2000, but current US regulations still restrict sale of products that include 128-bit AES encryption, to customers residing in pre-approved countries only.

If you create a project that makes use of the AES encryption features of vList, your country may have regulations that apply to the export of your product. Some countries, including the United States, have more relaxed export rules for 64-bit or shorter keys, so a customer planning to export a product that does not require a 128-bit key, may prefer to use weaker encryption.

Previous releases of vList distributed by updateStage, Inc were available in two different versions, one using 64-bit keys and the other using 128-bit ones, in order to comply with US export laws that affected updateStage, Inc. Version 1.8.6 and later however includes a new method, vList_encryptionStrenght(64), that can be used by the developer to restrict the cryptographic capabilities of vList at runtime. If you live in a country that limits the export of products using strong encryption, you may want to use this function to effectively reduce encryption strenght in vList, thus making your final product that uses vList compliant with export regulations that permit weaker keys.

Export legislation is constantly being revised and is different for each country, so if you have any legal questions regarding your particular situation please consult your lawyer.
