public string private_key_password { owned get; set; }
The password used to decrypt the private key specified in the NMSetting8021x:private-key
property when the private key
either uses the path scheme, or if the private key is a PKCS#12 format key.
Setting this property directly is not generally necessary except when returning secrets to NetworkManager; it is generally set automatically when setting the private key by the set_private_key function.
