I found this bit of interesting information on the net, it seems OS X has a built in command to calculate CRC's but it's in decimal only! A nice person made some code that you can add into your .bash_profile and have the hexadecimal value instead. Here's what you need to do:
1. Open terminal then type the following:
touch ~/.bash_profile
open -e ~/.bash_profile
2. This will open your .bash_profile, most likely it will be empty. Then you need to add this as a single line of code:
function crc32 { cksum -o3 "$@"|ruby -e 'STDIN.each{|a|a=a.split;printf "%08X\t%s\n",a[0],a[2..-1].join(" ")}'; }
Close .bash_profile and save changes. When you're done open Terminal, type crc32 and then drag over a file from your desktop, hit return. You will be given the crc32 in all it's glory.
I like this because it allows me to verify the file is indeed the same one (if the CRC32 is given) they had online (whoever). Good luck!
