Not able to strip password from private key

I am following this blog to create a mdm server link.

In the 7th step they are stripping password from the private key by running this command 

openssl rsa -in key.pem -out private.key

But when I run this command on my terminal I am getting error

unable to load Private Key 
routines:PEM_read_bio:no start line:pem_lib.c:703:Expecting: ANY PRIVATE KEY

I am working on mac. All the steps before that worked fine. In the previous step they asked to enter passphrase I pressed enter without passphrase, is this the reason for this error.

Hope you understand the problem

Thanks

Solution

  • I pressed enter without passphrase, is this the reason for this error.

    Yes, you are correct — since you didn't use a passphrase there's nothing to strip out in that step.

    Unfortunately the tutorial failed to mention anything about that before you arrived at your conclusion. A passphrase shouldn't (normally) be necessary anyway, as the important private key extracted earlier should be all that you would need.
