/**
* @file interest_nameA_crc32c.h
* @brief Interest with CRC validation
*
*
* Ground truth set derived from CRC RevEng http://reveng.sourceforge.net
* e.g. reveng -c -m CRC-32C 313233343536373839 gives the canonical check value 0xe306928e (the output will be backwards)
*
* You can also calcaulate CRC32C online at http://www.zorc.breitbandkatze.de/crc.html using
* CRC polynomial 0x1EDC6F41, init 0xFFFFFFFF, final 0xFFFFFFFF, reverse data bytes (check),
* and reverse CRC result before final XOR (check).
*
* you can get the packet dump from the "write_packets" command. here's the detailed steps.
* The -c size of 8 in steps 4 and 7 are chosen to make it easy to delete the right number of lines.
* there's nothing magic about the "8".
*
* 1) execute ./write_packets
* 2) xxd -r -c 8 v1_interest_nameA_crc32c.txt > y
* 3) Delete the first 24 bytes and last 8 bytes and display as a URI-escaped hex string
* head -c 57 y | tail -c +25 | xxd -p -c 256 | sed 's/[0-9a-f]\{2\}/%&/g'
* The string should be "00010015...00020000"
* 4) Copy the hex string to the website and use the settings specified above (don't use 0x in front
* of any hex strings). IMPORTANT: you need to %-escape each hex byte!! Click "compute!"
* 5) The answer should be 6AD7B1F2
* 6) Put the byte array from (5) in the Validation Payload.
