about the data
hello,
i only need to verify the data after i received it
the packet is of size 144 byte : message 140 byte +crc 4 byte
the messege received is a simple string and the crc send is a hexadecimal and received the same.
now i need to add the string and hexdecimal (so need to convert them both to same format)lets say convert the string to decimal (ascii value ) and hexdecimal to decimal.
and add the both......
then divide it by key .......i get the remainder zero if the message is not corrupted.
should this be the way to check the the packet validation of the data with the crc at the receiver end.
assume that i have received the data in the afore said format
thanking you

Eventually, it made more sense to associate a CRC-Digest with each colouring.
