Ken Shirriff’s blog : Mining Bitcoin with pencil and paper : 0.67 hashes per day

Notes
(…)
[2] The source of the constants used in SHA-256 is interesting. The NSA designed the SHA-256 algorithm and picked the values for these constants, so how do you know they didn’t pick special values that let them break the hash? To avoid suspicion, the initial hash values come from the square roots of the first 8 primes, and the Kt values come from the cube roots of the first 64 primes. Since these constants come from a simple formula, you can trust that the NSA didn’t do anything shady (at least with the constants).

You’re insane, but amazing. This is fantastic.
