关于RSA签名验签官网示例用openssl无法验证的问题
我想用openssl签名，用Go验签，在网上搜到了源码页，但源码页的结果和我的无法对应，如下
源码页
https://golang.org/src/crypto/rsa/pkcs1v15_test.go
其中的签名和验证代码：
```
// These vectors have been tested with
// `openssl rsautl -verify -inkey pk -in signature | hexdump -C`
var signPKCS1v15Tests = []signPKCS1v15Test{
{"Test.\n", "a4f3fa6ea93bcdd0c57be020c1193ecbfd6f200a3d95c409769b029578fa0e336ad9a347600e40d3ae823b8c7e6bad88cc07c1d54c3a1523cbbb6d58efc362ae"},
}
func TestSignPKCS1v15(t *testing.T) {
for i, test := range signPKCS1v15Tests {
h := sha1.New()
h.Write([]byte(test.in))
digest := h.Sum(nil)
s, err := SignPKCS1v15(nil, rsaPrivateKey, crypto.SHA1, digest)
if err != nil {
t.Errorf("#%d %s", i, err)
}
expected, _ := hex.DecodeString(test.out)
if !bytes.Equal(s, expected) {
t.Errorf("#%d got: %x want: %x", i, s, expected)
}
}
}
func TestVerifyPKCS1v15(t *testing.T) {
for i, test := range signPKCS1v15Tests {
h := sha1.New()
h.Write([]byte(test.in))
digest := h.Sum(nil)
sig, _ := hex.DecodeString(test.out)
err := VerifyPKCS1v15(&rsaPrivateKey.PublicKey, crypto.SHA1, digest, sig)
if err != nil {
t.Errorf("#%d %s", i, err)
}
}
}
// 私钥在页面最底部
// In order to generate new test vectors you'll need the PEM form of this key:
// -----BEGIN RSA PRIVATE KEY-----
// MIIBOgIBAAJBALKZD0nEffqM1ACuak0bijtqE2QrI/KLADv7l3kK3ppMyCuLKoF0

var rsaPrivateKey = &PrivateKey{

},
}
```
将上面的私钥写到文件key
用命令
echo -e "Test.\n" | openssl rsautl -sign -inkey key | hexdump -C
输出的是签名后的结果，如下：
```
00000000 89 e3 18 40 74 8b b0 cf 92 eb f4 65 57 ef 54 f5 |...@t......eW.T.|
00000010 f3 a0 2e 7f 7a f4 66 02 4f a6 18 62 2e b8 37 56 |....z.f.O..b..7V|

00000040
```
其中有效部分为 89e318...........
而官网示例中为 a4f3fa6ea93b........
openssl与上面源码中，签名后的结果对应不上，请问社区有无做过RSA的，帮忙看下.......
