Question

I Have basically calculated SHA512 hash and I get it in byte[], all I want to do is to store it in my DB, the current infrastructure is such that i need to create a XML of my data and this XML gets passed to a SP which inserts the data. So the flow becomes

byte[] -> string (using BitConverter) -> XML -> binary(64)(using OPENXML)

I think this can be improved, but unfortunately I cannot change the infrastructure, so the XML has to be in between, also what happens is that the XML data I had –

1031B4BFC79B4E6357FE271FF2313D37A90E29FCAAEC850E5C4044547C1184AE

becomes

0x31003000330031004200340042004600430037003900420034004500360033003500370046004500320037003100460046003200330031003300440033003700

in the db

This does not look like the binary form of original data. Any explanation on whats happening?

Answer 1

The string that comes out looks like little-Endian Unicode of the original hex string.

I.e., 0x3100 for ‘1’, 0x3000 for ‘0’, 0x3300 for ‘3’, 0x3100 for ‘1’, 0x4200 for ‘B’, etc.
