Hi,

I have a private key file and aim to retrieve the private key for 
utilization in other functions. In PHP, there exists a function 
named 'openssl_pkey_get_private' for this purpose. Is there a 
corresponding function available in D to achieve the same outcome?

Long story short, you need to understand OpenSSL BIO's and call into 
``PEM_write_bio_PKCS8PrivateKey`` with the ``EVP_PKEY`` already loaded 
which isn't the easiest thing to do.

My version of the code:

You'll also need an OpenSSL binding such as:
