Golang 1.2: Unzip password protected zip file?

Question

Looking at the latest release (1.2) zip package - how can I unzip a file that was password protected (using 7zip, AES-256 encoding)? I don\'t see where/how to add in that i

Answer 1

https://github.com/yeka/zip provides functionality to extract password protected zip file (AES & Zip Standard Encryption aka ZipCrypto).

Below is an example how to use it:

package main

import (
    "os"
    "io"
    "github.com/yeka/zip"
)

func main() {
    file := "file.zip"
    password := "password"
    r, err := zip.OpenReader(file)
    if nil != err {
        panic(err)
    }
    defer r.Close()

    for _, f := range r.File {
        f.SetPassword(password)
        w, err := os.Create(f.Name)
        if nil != err {
            panic(err)
        }
        io.Copy(w, f)
        w.Close()
    }
}

The work is a fork from https://github.com/alexmullins/zip which add support for AES only.
