Hi, all.
Yet another dumb question from me.
UEFI specification has Crc32 calculation service and uses Crc32 in
several places. but it only humbly mentions in the note somewhere in
the description of System Table about what exact one it wants. Namely
it states that the polynomial seed is 04c11db7. And that's all.
My question is - does really the specification means the 33-bit polynomial
104c11db7? And is the algorithm just a plain remainder calculation
without any additional pre/post processing of it? So that for example
Crc32 of the 4-byte sequence b16b00b5 would be
8c1f0a7c?
Thank you.
