我想将其转换为der和pem并用它签名文件，以便另一端可以使用其公钥来验证签名.

and I would like to convert it to der and pem and sign a file with it so that other side can verify the signature with their public key.

我正在尝试使用openssl和xxd在bash脚本中执行此操作，并且我正在考虑尝试使用python进行操作，但目前我无法使其正常工作.

I am trying to do it in a bash script using openssl and xxd and I'm considering to try with python maybe but somehow for now I can't make it work.

如果有人有任何想法，我很乐意听到.

If anyone has any ideas I would be happy to hear them.

例如，我可以使用 https://holtstrom.com/michael/将十六进制转换为pemtools/hextopem.php 在线转换器，我用----- BEGIN/END RSA PRIVATE KEY -----页眉/页脚将其保存在private_key.pem文件中，如果我检查专用模数和匹配项，它们匹配的公共密钥，但是我无法在任何地方加载该密钥以用于签名OpenSSL，也不会加载该密钥，因此我想我丢失了一些东西.

For instance I can convert hex to pem using https://holtstrom.com/michael/tools/hextopem.php online converter and I save it in private_key.pem file with -----BEGIN/END RSA PRIVATE KEY----- header/footer and if I check modulus of the private and matching public key they match but I can't load that key anywhere to use it for signing OpenSSL also won't load the key so I guess I'm missing something.

推荐答案

使用十六进制输入文件(rsa-key-hex.txt)，您可以执行以下操作-

With your hex input file (rsa-key-hex.txt), you can do the following -

将其转换为二进制文件(实际上是DER格式)-

Convert it to binary (which is actually DER format) -

xxd -r -ps rsa-key-hex.txt rsa-key.der

打印DER私钥-

openssl pkey -in rsa-key.der -inform der -noout -text

将其转换为PEM-

openssl pkey -in rsa-key.der -inform der -out rsa-key.pem -outform pem

使用私钥对某些输入进行签名-

Sign some input using the private key -

echo "Some Input" | openssl dgst -sha256 -sign rsa-key.pem > signature.dat

提取公钥-

openssl pkey -in rsa-key.pem -pubout -out rsa-key-pub.pem

使用公钥检查签名-

echo "Some Input" | openssl dgst -sha256 -verify rsa-key-pub.pem -signature signature.dat

或者，直接使用私钥检查签名-

Alternatively, check signature using the private key directly -

echo "Some Input" | openssl dgst -sha256 -prverify rsa-key.pem -signature signature.dat
