  encoded, encodingError := strenco.Encode(plaintext)
  if encodingError != nil {
    println(encodingError.Error())
  } else {
    println(encoded) // %%7z;1tsk1JA!NbAFwzj j&{r(3#"+L%m*{<D%Wrh@iyB(qM!eG)>B/ox/%%
  }
}

Decode encoded string

package main

import "github.com/julyskies/strenco"

func main() {
  encoded := `%%7z;1tsk1JA!NbAFwzj j&{r(3#"+L%m*{<D%Wrh@iyB(qM!eG)>B/ox/%%`
  decoded, decodingError := strenco.Decode(encoded)
  if decodingError != nil {
    println(decodingError.Error())
  } else {
    println(decoded) // Lorem ipsum dolor sit amet, consectetur adipiscing elit.

Security

This module is not secure, since its main goal is to make the original value unreadable. There are no additional keys, passphrases or secrets required, meaning that anyone can decode encoded value. It is not recommended to store sensitive data encoded with this module.
