我使用OpenSSL的命令对消息进行签名 “测试”，用hexdump都为什么我使用openssl和golang生成的RSA签名有所不同？

# echo "Test." | openssl rsautl -inkey privite.key -sign -hexdump 
0000 - 09 1b ce e2 4b 69 86 be-d7 b1 fb f0 ec e4 53 0e ....Ki........S.

十六进制字符串091bcee24b69输出...

生成签名与Golang

去运行这段代码，fo llowing输出： 52e1cce3810c1a89693cf6965d1035618820a9e3a7b95203d885c4153dc3f7424b98e3ba628a186f1074d672bb59a1c0788a9c2064951ca2326eb1bf8e3e49e9

但我认为它应该是：

091bcee24b69 ...

哪里是我的错吗？由于
