Hey NSA, should we tell everyone yet?

 

When does SHA256 (ivec,block) = ivec?

ivec: 2EC557A2 0B6E2499 0CF13E72 2CDD2309 CD4AB124 B54D3298 9FBAAA26 595767F4

block: 4E617468 616E4D61 7269656C 73800000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000068

hash: 2EC557A2 0B6E2499 0CF13E72 2CDD2309 CD4AB124 B54D3298 9FBAAA26 595767F4

 

Note that SHA256 (ivec,block) = SHA256 (ivec,block,block) for example above. sha256mt.c, sha256inv.cpp, sha256fixedpoints.c, sha256collisions.c
