Task

Demonstrate a method of deriving the Cyclic Redundancy Check from within the language.



The result should be in accordance with ISO 3309, ITU-T V.42, Gzip and PNG.

Algorithms are described on Computation of CRC in Wikipedia.
This variant of CRC-32 uses LSB-first order, sets the initial CRC to FFFFFFFF16, and complements the final CRC.

For the purpose of this task, generate a CRC-32 checksum for the ASCII encoded string:

 The quick brown fox jumps over the lazy dog


package main
 
import (
    "fmt"
    "hash/crc32"
)
 
func main() {
    s := []byte("The quick brown fox jumps over the lazy dog")
    result := crc32.ChecksumIEEE(s)
    fmt.Printf("%X\n", result)
}
