Question

是否可以从密钥中获取任何用户可读数据，如下所示

uchar DELTA_PUB_KEY[]  = {
0x7c, 0x5b, 0x31, 0x88, 0x25, 0x64, 0x43, 0xaa,
0x34, 0x97, 0x6b, 0x7d, 0x22, 0x9a, 0x56, 0xdd,
0x5e, 0xab, 0x2f, 0xd6, 0x10, 0x34, 0x12, 0x6b,
0x12, 0xfa, 0x34, 0x54, 0x33, 0xee, 0x32, 0xde,
0x13, 0x54, 0x12, 0x23, 0x98, 0x7e, 0xe6, 0xee
0x34, 0x72, 0x91, 0xfb, 0x67, 0x98, 0x56, 0x34
};

我要求查看与上面类似的密钥内部有什么内容。

以下命令

我应该得到什么信息

To print out the components of a private key to standard output:

     openssl rsa -in key.pem -text -noout

该命令是否会用于获取所需数据？我认为不可能从密钥中读取任何信息，但我需要你的意见。请帮我从密钥中获取数据。

Answer 1

如果您有结构化格式的密钥，例如PEM编码的RSAPrivateKey ASN.1对象，那么您可以使用OpenSSL等工具打印一些信息。通常，这只是密钥的标记部分。

例如，运行openssl rsa -in key.pem -text -noout会产生类似于：

您提供的示例数据似乎不是ASN.1，因此我不确定您可以从中获取哪些信息。它只有40个字节，所以也许它是320位RSA公钥的模数？如果是这样，那就非常弱，并且不值得使用。

是否可以从密钥中获取数据？
