The seeds of the NIST elliptic curves (P-256, P-386, etc.) were selected by the NSA and are rumored to be like
SHA-1("Jerry and Alice deserve a raise. 1398")
However, Jerry Solinas, who picked them, forgot them and then passed away this year.
We should crack them!
I'm announcing a $8,192 bounty (tripled if donated to charity) for anyone cracking these hashes and solving this mystery.
