Answer 1

OpenSSL

Answer 2

In general, data signed according to the pkcs12 specification can be stored in PEM format.
What is .rsa is not known. There is an RSA encryption algorithm. So, according to the pkcs12 specification, they can sign documents using this algorithm.
In your case, based on the openssl command, you simply get the content (-nocerts) from the signed document and for some reason call it xxxx.key
In general, PHP has functions for working with OpenSSL. Or you can call the necessary commands through shell_exec.
