Golang CRC (Cyclic Redundancy Check)

Comprehensive Go Language (Golang) CRC Library, Supporting CRC8, CRC16, CRC32 and CRC64.

CRC (Cyclic Redundancy Check) is an error detection algorithm that generates a checksum based on the data being transmitted. In Go (Golang), you can implement CRC using various algorithms, such as CRC-8, CRC-16, CRC-32 or CRC-64.

Get Started

• CRC-8 Usage

  1 - Importing package into main package

  import ("github.com/yousifnimah/Cryptx/CRC8")
  

  2 - Use algorithm name from the table below:

  Algorithm	Polynomial	Initial Value	XOROUT
  CRC-8	0x07	0x00	0x00
  ITU	0x07	0x00	0x55
  ROHC	0x07	0xFF	0x00
  SAE-J1850	0x1D	0xFF	0xFF
  SAE-J1850_ZERO	0x1D	0x00	0x00
  8H2F	0x2F	0xFF	0xFF
  CDMA2000	0x9B	0xFF	0x00
  DARC	0x39	0x00	0x00
  DVB_S2	0xD5	0x00	0x00
  EBU	0x1D	0xFF	0x00
  ICODE	0x1D	0xFD	0x00
  MAXIM	0x31	0x00	0x00
  WCDMA	0x9B	0x00	0x00

  In main.go:

  package main
  
  import (
  "fmt"
  "github.com/yousifnimah/Cryptx/CRC8"
  )
  
  func main() {
    Input := []byte("12345") //string to slice of bytes
    AlgorithmName := "ITU"   //CRC-8 algorithm name from supported table
    checksumHex := CRC8.ResultHex(Input, AlgorithmName)
    fmt.Println("Output:", checksumHex)
  }
  

  Result:

  Output: 0x9E
  

  You can get output in byte:

  Input := []byte("12345")
  checksumByte := CRC8.Result(Input, "ITU")
  fmt.Println("Output:", checksumByte)
