This program will create a ZIP archive, so we have an archive to use with our steganography experiments. The Go standard library has a zip package, but it also supports TAR archives with the tar package. This example generates a ZIP file with two files: test.txt and test2.txt. To keep it simple, the contents of each file is hard-coded as a string in this source code:
package mainimport ( "crypto/md5" "crypto/sha1" "crypto/sha256" "crypto/sha512" "fmt" "io/ioutil" "log" "os")func printUsage() { fmt.Println("Usage: " + os.Args[0] + " <filepath>") fmt.Println("Example: " + os.Args[0] + " document.txt")}func checkArgs() string { if len(os.Args) < 2 { printUsage() os.Exit(1) } return os.Args[1]}func main() { filename := ...
