Hex Byte CRC: Displays the CRC of your file (or selection) before XORed with Final XOR Value.For a 16-bit CRC, its low 16 bits will be used for a 32-bit CRC, the whole 32 bits will be used. Final XOR Value: Enter the value to be XORed with the final value of the CRC algorithm, in hex.Initial Value: Enter the initial value of the CRC algorithm, in hex.Note that the MSB of the polynomial must always be set.

Enter coefficients: This is a space for you to define a 16-bit or 32-bit CRC generator as a comma-separated list of polynomial coefficients.

Uncheck it to shift the MSB (bit 7) in a byte into the CRC algorithm first.

Bit Reflected: Check it to shift the LSB (bit 0) in a byte into the CRC algorithm first.

For example, enter the string '1024.2048, 0x4096, 512' will exclude the 1024 bytes starting at address 1024, the single byte at 0x4096, and the single byte at 512. Multiple addresses can be indicated using commas or semicolon, and a range of addresses can be indicated using '.' between two addresses.

Ignore Ranges: Select it to enable explicitly excluding centain byte ranges and enter the byte ranges in the associated edit box.

This option is disabled when no bytes is selected. Selection: Select it to apply a CRC algorithm to the current selection only. Whole File: Select it to apply a CRC algorithm to all bytes in the file. This feature is useful to calculate the hash value for file in which the actual hash value is stored and thus should be excluded from the calculation.

You can also explicitly exclude certain byte ranges by selecting Ignore Ranges check box and enter the ranges in the associated edit box. Otherwise, select the Selection radio box in the dialog will apply the CRC algorithm to the selected bytes only. If no bytes are selected when the CRC Value Calculator is activated, the CRC algorithm will be applied to the whole file. To activate the tool, you can choose CRC Value Calculator.

The CRC Value Calculator can be used to calculate a 16 and 32-bit CRC result or used to test and evaluate a variety of 16 and 32-bit CRC algorithms based on the parameters you specified. The procedure is known as a redundancy check because each transmission includes not only data but also additional, redundant values for error checking. If both devices obtain the same result, it is assumed the transmission was error-free. The receiving device repeats the same calculation after transmission. In CRC error checking, the sending device calculates a number based on the data transmitted.
