How to convert PKCS8 to PKCS1?

[scissorband]

I tried the command:

$ openssl pkcs8 -in server.key.pem pkcs1 -out newserver.key.pem -nocrypt

But the results of the new key are the exact same as the old PKCS8 formatted one.

I don't think you will be able to do this because the two PKCS standards are designed to do different functions:

PKCS1 is designed for encrypting and signing Public Keys

PKCS8 is designed for dealing exclusively with Private Keys


So, I don't think you could just convert one to the other.....but I'm not an expert.

Try the openssl community for more details.
