func EqualSumCastagnoli ¶
EqualSumECMA compares CRC32 hash using crc32.Castagnoli table. It returns if the sum matches to the hash of b.
func EqualSumIEEE ¶
EqualSumIEEE compares CRC32 hash using crc32.IEEE table. It returns if the sum matches to the hash of b.
func EqualSumKoopman ¶
EqualSumECMA compares CRC32 hash using crc32.Koopman table. It returns if the sum matches to the hash of b.
func SumCastagnoli ¶
SumCastagnoli returns CRC32 hash using crc32.Castagnoli table. It uses hash/crc32.New.
Example ¶
package main
import (
"encoding/hex"
"fmt"
"github.com/aileron-projects/go/zhash/zcrc32"
)
func main() {
// Calculate CRC32 hash using [crc32.Castagnoli] table.
// Validation data can be generated with:
// - https://www.sunshine2k.de/coding/javascript/crc/crc_js.html
// - https://crccalc.com/?crc=Hello%20Go!&method=CRC-32&datatype=ascii&outtype=hex
sum := zcrc32.SumCastagnoli([]byte("Hello Go!"))
encoded := hex.EncodeToString(sum)
fmt.Println(len(sum), encoded)
}
Output: 4 c83c2422
func SumIEEE ¶
SumIEEE returns CRC32 hash using crc32.IEEE table. It uses hash/crc32.New.
Example ¶
package main
import (
"encoding/hex"
"fmt"
"github.com/aileron-projects/go/zhash/zcrc32"
)
func main() {
// Calculate CRC32 hash using [crc32.IEEE] table.
// Validation data can be generated with:
// - https://www.sunshine2k.de/coding/javascript/crc/crc_js.html
// - https://crccalc.com/?crc=Hello%20Go!&method=CRC-32&datatype=ascii&outtype=hex
sum := zcrc32.SumIEEE([]byte("Hello Go!"))
encoded := hex.EncodeToString(sum)
fmt.Println(len(sum), encoded)
}
Output: 4 48e1410f
func SumKoopman ¶
SumKoopman returns CRC32 hash using crc32.Koopman table. It uses hash/crc32.New.
Example ¶
package main
import (
"encoding/hex"
"fmt"
"github.com/aileron-projects/go/zhash/zcrc32"
)
func main() {
sum := zcrc32.SumKoopman([]byte("Hello Go!"))
encoded := hex.EncodeToString(sum)
fmt.Println(len(sum), encoded)
}
Output: 4 1f83620a
