Base64 encoding

Context

The encoding/base64 package encodes and decodes Base64. Use StdEncoding for standard Base64, URLEncoding for URL‑safe.

Example

Encode and decode a string.

Code example

package main

import (
    "encoding/base64"
    "fmt"
)

func main() {
    data := []byte("hello world")
    encoded := base64.StdEncoding.EncodeToString(data)
    fmt.Println(encoded)

    decoded, _ := base64.StdEncoding.DecodeString(encoded)
    fmt.Println(string(decoded))
}

Output

aGVsbG8gd29ybGQ=
hello world
