package hash/crc32
New creates a new hash.Hash32 computing the CRC-32 checksum using the polynomial represented by the Table.
MakeTable returns the Table constructed from the specified polynomial.
Golang hash/crc32.New and MakeTable functions usage example
package main
import (
"fmt"
"hash/crc32"
)
var castagnoliTable = crc32.MakeTable(crc32.Castagnoli) // see http://golang.org/pkg/hash/crc32/#pkg-constants
func main() {
crc := crc32.New(castagnoliTable)
crc.Write([]byte("abcd"))
fmt.Printf("Sum32 : %x \n", crc.Sum32())
}
Output :
Sum32 : 92c80a31
