Base32 是一种二进制到文本的编码，用字母 A-Z 和数字 2-7 表示字节。此工具使用带填充的 RFC 4648 字母表。
当编码数据需要不区分大小写，或需要避免视觉上易混淆的符号，同时仍保持纯文本形式时，Base32 很有用。
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
}
