CRC Calculator is an online tool to compute CRC checksum using all implementations of CRC-8, CRC-10, CRC-11, CRC-12, CRC-13, CRC-14, CRC-15, CRC-16, CRC-24, CRC-31, CRC-32, CRC-40 and CRC-64. This hash can be used to verify the integrity of the data during transmission. You can provide the expected hash and compare the calculated CRC checksum with it. The CRC hash can be generated in Base64, Hex or Integer formats. The input can be provided in Plain Text or Base64. Hit the Calculate button to generate and check the CRC value.

CRC is an old & widely used algorithm to verify the integrity of data during transmission. It has been used in networks & storage devices to detect data corruption. CRC stands for Cyclic Redundancy Check. It has two variants CRC-16 and CRC-32. They use different number of bits in the algorithm. The former uses 16 bits while the latter uses 32 bits.

The result of CRC-10 to CRC-16 is not correct with the magic check value (always 8-bit).
It seems like the other MSB bits are hidden, could you please have a check?

The check parameter represents the checksum obtained on feeding "123456789" ASCII input to the algorithm. As such, it is a constant value irrespective of the input.
Chau Huynh Copy Link
As I said, for CRC-10 to CRC-16, if the input is ASCII 123456789, the CRC result is not correct.
For an example of CRC-10, the result is 0x99 while 0x199 is expected as magic check value.
The MSB bit is not included in the final CRC result.

Can i get the exe of the same crc calculator for CRC-16. By using that exe, we can pass the file as input and get the CRC16 result.
