Decrypt PEM containing key and certificate

Question

I have a .pem file which contains both my certificate and encrypted private key, ie:

Bag Attributes
....
-----BEGIN CERTIFICATE-----
....
-----END CERTIFICATE-----
Bag Attributes
....
-----BEGIN ENCRYPTED PRIVATE KEY-----
....
-----END ENCRYPTED PRIVATE KEY-----

And I need to instead have a .pem file containing both the certificate and the decrypted private key. How can I achieve this on linux, preferrably utilising the openssl application?

Answer 1

To decrypt a private key from a pem file you would do something like this with a subcommand (rsa pkcs8, pkcs12):

openssl rsa -in inputfilename -out outputfilename

Your input file is different because you concatenated both keys in one file. But you can simple edit the pem file to split it in 2 files.
