> It's all stolen from America?

No, it=92s not "all stolen from America", they have universities, Chinese c=
rypto conferences, their own crypto standards. Quite a long history indepen=
dent of the US. =


Cryptography is quite an open subject. There are quite a few good conferenc=
es where these things are shared publicly and the Chinese do attend. =

	http://www.iacr.org

Cryptographers of Chinese origin have made significant advances in western =
Cryptography. =

	Xuejia Lai: http://en.wikipedia.org/wiki/International_Data_Encryption_Alg=
orithm
	Xiaoyun Wang: The startling demise of MD5
	Andrew Chi-Chih Yao: Received the turing award for complexity-based theory=
 of pseudorandom number generation, cryptography, and communication complex=
ity.

> Good call though. Wonder if they have their own cyphers.

One algorithm that I know of, SMS4 has had public cryptanalysis. =

	http://en.wikipedia.org/wiki/SMS4
They offered it for a standard and was rejected even there has been no flaw=
 found. =


> Maybe their espionage works well. In that case they can know if the Ameri=
cans have tricks around their own cyphers, and they just use those that can=
't be broken. Or that can be broken, in those special cases.


Every country that has the means, has their own cryptography and cryptanaly=
sis capability.
