Decrypt not handle illegal string error

[JiajunDou]

Hello,

I encountered an issue with the following code:

func Decode(s string) (string, error) {
	cipher := dongle.NewCipher()
	cipher.SetMode(dongle.CBC)      // CBC、CFB、OFB、CTR、ECB
	cipher.SetPadding(dongle.PKCS7) // No、Zero、PKCS5、PKCS7
	cipher.SetKey(c.AUTH_KEY)       // key must be 16, 24 or 32 bytes
	cipher.SetIV(c.IV_KEY)
	e := dongle.Decode.FromString(s).ByBase62()
	if e.Error != nil {
		return "", e.Error
	}
	raw := e.ToBytes()

	f := dongle.Decrypt.FromRawBytes(raw).ByAes(cipher)
	if f.Error != nil {
		return "", f.Error
	}
	return f.ToString(), nil
}

_, mustError := Decode("123")
if mustError != nil {
	fmt.Println(mustError.Error())
}

golang version: 1.19

dongle version: 0.2.0

I expected to get:

Error.Error()

But I actually get:

 (*cbcDecrypter).CryptBlocks: panic("crypto/cipher: input not full blocks")
go/pkg/mod/github.com/golang-module/dongle@v0.2.0/cipher.go:126 (0xddbec1)

Thanks!
