Given enough cpu time, and knowing you'll find the identity of spies, I think China and Russia would be more than capable to crack quite a bit of encryption even with brute force.
- semi-extrinsic 11y agoYeah... That's not how encryption works. If I use AES-256 to encrypt "I'll be late for dinner" padded with a paragraph of Lorem Ipsum, even the US/Russia/China are incapable of breaking that even in a hundred years of supercomputer crunching. Unless they have a backdoor of course.

- Radim 11y agoWell if you start out by assuming you know the secret message already, then there is exactly 1 possibility and "cracking it" takes exactly 0 seconds.

- vidarh 11y agoThat's just not how it works. To confirm you have the right message, you will need to guess the key and confirm it results in the same encrypted message. Note that he said (and I misread this too) to pad the message with lorem ipsum, not to use lorem ipsum as the key. If you want to go the other way, and guess the plaintext and then confirm it, you've now made what was an "impossible" problem massively more difficult.
