This fork add support for Standard Zip Encryption.
|
|
|
|
The work is based on https://github.com/alexmullins/zip
|
|
|
|
Available encryption:
|
|
|
|
```
|
|
zip.StandardEncryption
|
|
zip.AES128Encryption
|
|
zip.AES192Encryption
|
|
zip.AES256Encryption
|
|
```
|
|
|
|
## Warning
|
|
|
|
Zip Standard Encryption isn't actually secure.
|
|
Unless you have to work with it, please use AES encryption instead.
|
|
|
|
## Example Encrypt Zip
|
|
|
|
```
|
|
package main
|
|
|
|
import (
|
|
"bytes"
|
|
"io"
|
|
"log"
|
|
"os"
|
|
|
|
"git.internal/re/zip"
|
|
)
|
|
|
|
func main() {
|
|
contents := []byte("Hello World")
|
|
fzip, err := os.Create(`./test.zip`)
|
|
if err != nil {
|
|
log.Fatalln(err)
|
|
}
|
|
zipw := zip.NewWriter(fzip)
|
|
defer zipw.Close()
|
|
w, err := zipw.Encrypt(`test.txt`, `golang`, zip.AES256Encryption)
|
|
if err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
_, err = io.Copy(w, bytes.NewReader(contents))
|
|
if err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
zipw.Flush()
|
|
}
|
|
```
|
|
|
|
## Example Decrypt Zip
|
|
|
|
```
|
|
package main
|
|
|
|
import (
|
|
"fmt"
|
|
"io/ioutil"
|
|
"log"
|
|
|
|
"git.internal/re/zip"
|
|
)
|
|
|
|
func main() {
|
|
r, err := zip.OpenReader("encrypted.zip")
|
|
if err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
defer r.Close()
|
|
|
|
for _, f := range r.File {
|
|
if f.IsEncrypted() {
|
|
f.SetPassword("12345")
|
|
}
|
|
|
|
r, err := f.Open()
|
|
if err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
|
|
buf, err := ioutil.ReadAll(r)
|
|
if err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
defer r.Close()
|
|
|
|
fmt.Printf("Size of %v: %v byte(s)\n", f.Name, len(buf))
|
|
}
|
|
}
|
|
```
