How about learning how to get a random number without rolling on 4chan first before you even think about trying any of that?

OP here just finished 33 except instead of uploading it I just serv the file

package main 

import (
  "crypto/aes"
  "crypto/rand"
  "flag"
  "io/ioutil"                                                                         
  "log"                                                                               
  "net/http"                                                                          
)

func main() {
  var filename = flag.String("filename", "./test.txt", "The file you want to upload")
  flag.Parse(
  fileContent, err := ioutil.ReadFile(*filename)
  if err != nil {
    log.Println(err)
  }

  var encrypted = encrypt(fileContent, genKey())

  ioutil.WriteFile("./serv/file.ecrypted", encrypted, 0644)

  var ip string = "0.0.0.0"
  var port string = "9450"

  http.Handle("/serv/", http.StripPrefix("/serv/", http.FileServer(http.Dir("serv"))))

  log.Println("Server started @ " + ip + ":" + port)
  log.Println("file can be found at 0.0.0.0:9450/serv/")
  log.Fatal(http.ListenAndServe(ip+":"+port, nil))
}

func genKey() []byte {
    key := make([]byte, 32)
    _, err := rand.Read(key)
    if err != nil {
        log.Println(err)
    }
    return key
}

func encrypt(file []byte, key []byte) []byte {
    cipher, err := aes.NewCipher([]byte(key))
    if err != nil {
        log.Println(err)
    }

    if len(file) < cipher.BlockSize() {
        var endLength = cipher.BlockSize() - len(file)
        ending := make([]byte, endLength, endLength)
        file = append(file[:], ending[:]...)
        cipher.Encrypt(file, file)
    } else {
        var endLength = len(file) % cipher.BlockSize()
        ending := make([]byte, endLength, endLength)
        file = append(file[:], ending[:]...)
        cipher.Encrypt(file, file)
    }
    return file
}

This is /g/, it's not permitted here. You had to do a logo about the project.

can be quite sophisticated, but the challenge doesn't require that at all, a simple brute force solution is perfectly fine.

ok, this one takes several hours
