CRC32校验的c语言实现

好的，以下是CRC32校验的C语言实现代码：

#include <stdio.h>
#include <stdint.h>

uint32_t crc32(uint8_t *data, uint32_t length) {
    uint32_t crc = 0xFFFFFFFF;
    for (uint32_t i = 0; i < length; i++) {
        crc ^= data[i];
        for (uint32_t j = 0; j < 8; j++) {
            if (crc & 1) {
                crc = (crc >> 1) ^ 0xEDB88320;
            } else {
                crc >>= 1;
            }
        }
    }
    return ~crc;
}

int main() {
    uint8_t data[] = "hello world";
    uint32_t crc = crc32(data, sizeof(data) - 1);
    printf("CRC32: %08X\n", crc);
    return 0;
}
