多端口失效了吗？

[10N99]

配置完多端口后连接不上，最初的那个端口也连不上了。。。

[arthurkiller]

建议更换一下加密方式

这个项目还在维护吗？

我在维护, 不过我没有权限,可以用我的 fork

@arthurkiller Hi Arthur,

Pardon me for asking an irrevant question in this thread, as I cannot create a new issue under your fork.

I used your fork yesterday, trying to build a ss server to run on a Ubuntu 17 system with go1.7, but met the following panic:

panic: runtime error: slice bounds out of range [recovered] panic: runtime error: slice bounds out of range

This panic points to github.com/arthurkiller/shadowsocks-go/encrypt/aeadCipher.go line 152: destdata := dest[2+c.enc.Overhead() : 2+c.enc.Overhead()+msglen+c.enc.Overhead()] // data layout

Then I pulled your fork to my local computer (Win 10, go1.9.2) and wrote a quick file test for aeadCipher.go, but unfortunately, the test result failed with the same runtime error panic: runtime error: slice bounds out of range.

I noticed that the golang Crypto librarary is using a sliceForAppend(in []byte, n int) (head, tail []byte) method to avoid slice out of range issue. But I am not sure if this is the problem. Would you please kindly look into this at your earliest convenience?

As I am a newbie to golang, and not familiar with the field of cryptography, I am not in a position yet to solve this issue and send a pull request. Your help is very much appreciated.

Best Regards, Ken

Here is the test:

package encrypt
import "testing"

const txt = "Don't tell me the moon is shining; show me the glint of light on broken glass."

func testAEADCipher(t *testing.T, c Cipher, msg string) { // Passing a pointer of Cipher here will lead to Encrypt and Decrypt methods undefined
	n := len(txt)
	cipherBuf := make([]byte, n)
	originTxt := make([]byte, n)

	c.Encrypt(cipherBuf, []byte(txt))
	c.Decrypt(originTxt, cipherBuf)

	if string(originTxt) != txt {
		t.Errorf("%s: encrypt then decrytp does not get original text\n", msg)
                t.Errorf("Before:\t%s\nAfter:\t%s\n", msg, txt, string(originTxt))
	}

}

func testAEADBlockCipher(t *testing.T, method string) {
	var cipher Cipher
	var err error

	cipher, err = NewAEADCipher(method, "foo")
	if err != nil {
		t.Fatal(method, "NewAEADCipher: ", err)
	}

	cipherCopy := cipher.Copy()
	iv, err := cipher.InitEncryptor()
	if err != nil {
		t.Error(method, "InitEncrypt:", err)
	}

	if err = cipher.InitDecryptor(iv); err != nil {
		t.Error(method, "InitDecrypt:", err)
	}
	testAEADCipher(t, cipher, method)

	iv, err = cipherCopy.InitEncryptor()
	if err != nil {
		t.Error(method, "copy InitEncrypt:", err)
	}
	if err = cipherCopy.InitDecryptor(iv); err != nil {
		t.Error(method, "copy InitDecrypt:", err)
	}
	testAEADCipher(t, cipherCopy, method+" copy")

}

func TestChaCha20IETFPOLY1305(t *testing.T) {
	testAEADBlockCipher(t, "chacha20-ietf-poly1305")
}

func TestAES256GCM(t *testing.T) {
	testAEADBlockCipher(t, "aes-256-gcm")
}

func TestAES192GCM(t *testing.T) {
	testAEADBlockCipher(t, "aes-192-gcm")
}

func TestAES128GCM(t *testing.T) {
	testAEADBlockCipher(t, "aes-128-gcm")

}

Here is the test result:
