As much as I like the idea, I don't think I will implement a good and easy to use CRC tool in MCT. I just don't have the time for it. Also, there are really good external tools for this. Check out reveng crc.

I really can't stand using an online CRC calculator on a mobile device.I was looking for a convenient and quick CRC calculator, but I didn't find it.Can you tell me if I have any software like this？

I understand, but unfortunately I don't know any good CRC calculator for Android. There is Hashr which can calculate CRC32 of files and text. But I don't think this will help you much.

You could also try to "download" an Javascript-based online CRC calculator with tools like HTTrack. I never tried it though.

I will keep this issue open as feature request for a CRC calculator tool. But I can't say if and when I will have the time to write such a calculator and what CRC algorithm it will support.

Much appreciated if you could include this

Which CRC version is needed? Classical CRC32, or something else?

Well, I was thinking of "all" typical checksums - cryptographic and non cryptographic. Much like the checksum tool of the popular HxD editor.

something like this would be perfect
