#1 I wonder if the taking of the P3 intelligence aircraft contributed to the Chinese advances in code breaking. I don't think the crew had a chance to destroy all of their equipment.

#2 Wouldn't be surprised, Jonathan, and James Dunnigan reported here (StrategyPage) on Chinese cyberwarfare ... this **** is heating up real fast ... I'd feel more confident if we knew for sure how much farther ahead the US is than China, but that's not known to civilians for a good reason.

#3 That's not Signal Orange. That's some Ft. Lauderdale designer color.

#5 I've been out of the business for 6 years, but SHA is just a hashing algorithm. Does "breaking" it simply mean you found a way to know what changes in the text will produce what changes in the hash? You can't run the sausage grinder backwords, since the hash is only 20(?) bytes long.

This could be used to tamper with digitally signed documents, I guess. But it can't be used to actually forge the signatures or timestamps. Though I suppose you could dink with the message until a hash came out that corresponded to one that your target did sign. But the timestamp would still be wrong.

As I said, I left the field in 1999.

#6 Why do they need to break the codes? Plenty of Chinese and ABC who have more loyalty to China than their adopted homeland. Just steal the data.
