Cyclic Redundancy Check (CRC) is a common technique for detecting errors in data transmission. In CRC error checking, the sending device calculates a number based on the data transmitted. The receiving device repeats the same calculation after transmission. If both devices obtain the same result, it is assumed the transmission was error-free. The procedure is known as a redundancy check because each transmission includes not only data but also additional, redundant values for error checking.

This Hpmbcalc CRC tool 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. To activate the tool, you can choose CRC Value Calculator... item From the Tools menu.

If you use a file as the source of input bytes, you can explicitly exclude certain byte ranges by selecting Ignore Ranges check box and enter the ranges in the associated edit box. This feature is useful to calculate the CRC-value for file in which the actual CRC-value is stored and thus should be excluded from the calculation.
