encoding/base32
关于 base32 的信息查看 wiki 和 RFC 4648。
两个 Encoding
- StdEncoding
- HexEncoding
例如：
package main
import (
"encoding/base32"
"fmt"
)
func main() {
msg := []byte("Hello world. 你好，世界！")
encoded := base32.StdEncoding.EncodeToString(msg)
fmt.Println(encoded)
// JBSWY3DPEB3W64TMMQXCBZF5UDS2LPPPXSGOJOEW46KYZ354QE======
decoded, _ := base32.StdEncoding.DecodeString(encoded)
fmt.Println(string(decoded))
// Hello world. 你好，世界！
encoded = base32.HexEncoding.EncodeToString(msg)
fmt.Println(encoded)
// 91IMOR3F41RMUSJCCGN21P5TK3IQBFFFNI6E9E4MSUAOPRTSG4======
decoded, _ = base32.HexEncoding.DecodeString(encoded)
fmt.Println(string(decoded))
// Hello world. 你好，世界！
}
