Base32 is a binary-to-text encoding that represents bytes using the letters A-Z and digits 2-7. This tool uses the padded RFC 4648 alphabet.
Base32 is useful when encoded data must be case-insensitive or avoid visually confusing symbols while remaining plain text.
Hello -> JBSWY3DP
JBSWY3DP -> Hello// npm install hi-base32
const base32 = require('hi-base32');
const encoded = base32.encode('Hello');
console.log(encoded);
// Output: JBSWY3DP
const decoded = Buffer.from(base32.decode.asBytes('JBSWY3DP')).toString('utf8');
console.log(decoded);
// Output: Hello
package main
import (
"encoding/base32"
"fmt"
)
func main() {
encoded := base32.StdEncoding.EncodeToString([]byte("Hello"))
fmt.Println(encoded)
// Output: JBSWY3DP
decoded, _ := base32.StdEncoding.DecodeString("JBSWY3DP")
fmt.Println(string(decoded))
// Output: Hello
