- Get the private key from the key pair.
- Get the public key of the key pair.
- You need to do some modification to the private key -> pkcs8 format.
- Get those files.

Can I get a public key from a private key?
So in most practical implementations of RSA you can get the public key from the private key.
How do I get a public key certificate?
There are a couple of ways to do this. If for some reason you have to use the openssl prompt, just enter everything up to the “>”. OpenSSL will then print the public key information to the screen. You can then copy this and paste it into a file called pubkey.
Can a private key be recovered?
If you have a private key but you’re not sure it matches the certificate you received from the certificate authority, simply go here to check. In case the RSA key is deleted from the server and there is no way to restore it, Reissue is the only way out. You will need to generate a new CSR code/RSA key pair.
How do I find the key of a .PEM file?
Generation of a private EC key
- Generate an EC private key, of size 256, and send it to a file named key.pem: openssl ecparam -name prime256v1 -genkey -noout -out key.pem.
- Extract the public key from the key pair, which can be used in a certificate: openssl ec -in key.pem -pubout -out public.pem read EC key write EC key.
the .key file corresponds to the private key itself. If you open your .key file in a text editor, you will see that they have —–BEGIN RSA PRIVATE KEY—– as a prefix and —–END RSA PRIVATE KEY—– as a suffix. See below for example: The command you shared generates a public key pair from the existing private key.
Extracting certificate and private key information from a Personal Information Exchange (.pfx) file with OpenSSL: Open Windows File Explorer. Copy your .pfx file to a computer that has OpenSSL installed, making a note of the file path. Certificate.pfx files are usually password protected. Get the password for your .pfx file.
How can I get the public key from server.key?
I searched and found that I can get the public key by openssl rsa -in server.key -pubout -out key.pub How can I get the private key from server.key? the .key file corresponds to the private key itself.
Extract the private key from PFX. The following command will extract the private key from the .pfx file. A new private-key.pem file will be created in the current directory. This command required a password set in the pfx file. Open the output file (private-key.pem) and copy the text between —–BEGIN PRIVATE KEY—– and —–END CERTIFICATE—– and the final text.
