Base64 in every programming language
Encode Base64 in Python, Golang, PHP and others.
Python Base64 Encode and Python Base64 Decode: Base64 in Python programming language
Typically, Python is already available in your shell. You may just run python and get into Python REPL (Read–eval–print loop). In Linux you may need to install an additional package to run Python shell.
import base64
base64.b64encode('Example string'.encode('utf-8')) # will output b'RXhhbXBsZSBzdHJpbmc='
base64.b64decode(b'RXhhbXBsZSBzdHJpbmc=') # will output b'Example string'
PHP Base64 Encode and Base64 PHP Decode: Base64 in PHP programming language
Best way to play around with PHP is to use the official Docker image. To run interactive PHP shell from the Docker image, just run docker run -it --rm php bash -c "php -a". This command will download the latest Docker PHP image, then run container from this image in interactive mode, then run bash shell and the php -a command (PHP interactive mode) in this shell. Once > php interactive welcome appear, you’ll be able to play the code below.
$str = 'Example string'; echo base64_encode($str); # will output RXhhbXBsZSBzdHJpbmc= $encoded = 'RXhhbXBsZSBzdHJpbmc='; echo base64_decode($encoded); # will output Example string
Golang Base64 Encode and Golang Base64 Decode: Base64 in Go programming language
The following Golang program will encode to base64 the ‘Example string’ and decode the string back. Note the []byte(msg) and string(decoded) typecasts. EncodeToString expects the array of bytes as an input, and DecodeString outputs raw bytes, that’s why we have to apply conversion.
The official Golang documentation of the package base64
package main
import (
"encoding/base64"
"fmt"
)
func main() {
msg := "Example string"
encoded := base64.StdEncoding.EncodeToString([]byte(msg))
fmt.Println(encoded)
decoded, err := base64.StdEncoding.DecodeString(encoded)
if err != nil {
fmt.Println("decode error:", err)
return
}
fmt.Println(string(decoded))
}
