Re: An unbreakable backdoor would be nice
"Currently, any encryption algorithm using a key, or key pair, wider than 1024 bits falls under ITAR, and is considered munition. It cannot be exported to any country without prior permission from the US Department Of Commerce - Bureau of Industry and Security."
I'm sorry, but after reviewing your link, I'm just not able to confirm your assertion. It seems to even directly contradict it:
"There is no "unexportable" level of encryption under license exception ENC. Most encryption products can be exported to most destinations under license exception ENC, once the exporter has complied with applicable reporting and classification requirements."
