PKCS12_decrypt_skey() Decrypt the PKCS#8 shrouded keybag contained within bag using the supplied password
       pass of length passlen.

       PKCS12_decrypt_skey_ex() is similar to the above but allows for a library context ctx and property query
       propq to be used to select algorithm implementations.

PKCS12_decrypt_skey_ex() was added in OpenSSL 3.0.

       PKCS12_decrypt_skey, PKCS12_decrypt_skey_ex - PKCS12 shrouded keyBag decrypt functions

       Both functions will return the decrypted key or NULL if an error occurred.
