Geocache Description:


Your task is to find the salt for the CRC32 on site at the start of this multi.

You are looking for two hex numbers - but one is enough, since the first part are the same in both. You need the equal part.

The numbers:
ab:cd:ef:04:78:8F
ab:cd:ef:A6:41:F7

p: can be any char from "0".."Z". You need to compute the right one.
Salt = "abcdef" + p

Assuming final are stored in the format: "N55 yy.xxx" and "E12 yy.xxx" you need to match:

CRC32 for salt + N: 1198225983
CRC32 for salt + E: 2556988131


Example:

Number: 12:34:56:04:78:8F
Salt = "123456" + p

If salt = "123"
CRC32 for salt + "Tirsdagsholdet" are: 3726293802
