I need to calculate the CRC
You still aren't answering the question of why you need this?
That is, the normal reason for calculating a crc is to detect transmission errors; but to do that, you need the crc as calculated prior to transmission to compare against. (Or if you are the transmitter; then a full description of the CRC algorithm expected by the receiver.
I'll be more specific: is the CRC algorithm you wish to use 'Rocksoft Model CRC Algorithm'?
If so, the full parameter set for teh algorithm should read something like:
By the way, as far as I understand, the digest::CRC consider the data as an ASCII string. Meaning it takes each char, gets it ascii value, and then convert it to BIN. This is not what I need.
To do that, you'll need to know whether the CRC should be calculated for the data bytes alone; or should the preceding addresses be included some how?
What format is the data file in? Ie. Where does it come from? What produces it?
