Cryptography import/export limits

[laurensb]

Hello,

I am currently doing research into cryptography export limits and have searched Google extensively but have not found a conclusive answer to my question.

A while back the United States relaxed it's import and export laws regarding encryption which is why software such as Firefox and Internet Explorer could provide 128-bit ciphers outside of the U.S. I have however heard that the same does not hold true for software that is not freely available. What if I were to use RSA encryption? Would I have to limit the cipher strength if I would want to communicate with the U.S.?

Thanks!

Wow I typed "us cryptography" and export restriction laws was number one on google's "auto fill" list. As such here is the official government page on the topic.
