Struct ipworksencrypt::DPAPI

Properties Methods Events Config Settings Errors

The DPAPI struct allows you to protect and unprotect data.

Syntax

ipworksencrypt::DPAPI

Remarks

On Windows, the struct supports the classic Microsoft Windows Data Protection API (DPAPI) or CNG DPAPI implementation. The use of use_cng determines which implementation is used. Support for macOS is also available via the macOS keychain.

The classic DPAPI functionality protects data on a single system. The CNG DPAPI is designed with modern use cases involved. In many cases, especially with cloud computing, protection and unprotection may be done on different systems. With this in mind the Microsoft CNG DPAPI allows encrypting to a set of principals that can be used to unprotect the data on other systems after authenticating. On macOS, a key is saved in the Keychain which is used to protect and uprotect data.

Protecting Data

protect protects the specified data.

When using classic DPAPI (use_cng is False), the following optional properties are applicable:

data_description
password
prompt_title
prompt_user

When using CNG DPAPI (use_cng is True), the following properties are applicable:

protection_descriptor (required)
EscapeDescriptor
UseStreamMode

On macOS, the following settings are applicable:

UseSystemKeychain
KeychainServiceName

Input and Output Properties

The struct will determine the source and destination of the input and output based on which properties are set.

The order in which the input properties are checked is as follows:

input_file
input_message

When a valid source is found, the search stops. The order in which the output properties are checked is as follows:

output_file
output_message: The output data is written to this property if no other destination is specified.

Code Example (Classic DPAPI - use_cng is False)

//Protect DPAPI dpapi = new DPAPI(); dpapi.InputMessage = "test"; dpapi.Protect(); byte[] protectedData = dpapi.OutputMessageB; //Unprotect dpapi = new DPAPI(); dpapi.InputMessageB = protectedData; dpapi.Unprotect(); Console.WriteLine(dpapi.OutputMessage); //outputs "test"

Code Example (CNG DPAPI - use_cng is True)

//Protect DPAPI dpapi = new DPAPI(); dpapi.UseCNG = true; dpapi.ProtectionDescriptor = "LOCAL=user"; dpapi.InputMessage = "test"; dpapi.Protect(); byte[] protectedData = dpapi.OutputMessageB; //Unprotect dpapi = new DPAPI(); dpapi.UseCNG = true; dpapi.InputMessageB = protectedData; dpapi.Unprotect(); Console.WriteLine(dpapi.OutputMessage); //outputs "test"

Code Example (macOS)

//Protect DPAPI dpapi = new DPAPI(); dpapi.Config("UseSystemKeychain=false"); dpapi.Config("KeychainServiceName=nsoftware OSDP User Key"); dpapi.InputMessage = "test"; dpapi.Protect(); byte[] protectedData = dpapi.OutputMessageB; //Unprotect dpapi = new DPAPI(); dpapi.Config("UseSystemKeychain=false"); dpapi.Config("KeychainServiceName=nsoftware OSDP User Key"); dpapi.InputMessageB = protectedData; dpapi.Unprotect(); Console.WriteLine(dpapi.OutputMessage); //outputs "test"

Unprotecting Data

unprotect unprotects the specified data.

Object Lifetime

The new() method returns a mutable reference to a struct instance. The object itself is kept in the global list maintained by IPWorksEncrypt. Due to this, the DPAPI struct cannot be disposed of automatically. Please, call the dispose(&mut self) method of DPAPI when you have finished using the instance.

Remarks

This property specifies the protection descriptor rule string. The protection descriptor is used by the system to decide which entities can unprotect the data at a later time. This property must be specified before calling protect. This property is populated after calling unprotect.

Protection descriptors can be defined for the following types of authorization:

A local user or machine
An account or group in an Active Directory forest
A set of web credentials
A certificate in the user's certificate store

A local user or machine may be used for machines that are or are not on a domain. For instance:

LOCAL=user
LOCAL=machine

The use of SID and SDDL requires that the machine be part of a domain. For instance:

SID=S-1-5-21-4392301 AND SID=S-1-5-21-3101812
SDDL=O:S-1-5-5-0-290724G:SYD:(A;;CCDC;;;S-1-5-5-0-290724)(A;;DC;;;WD)

Certificates may also be used as a descriptor. To decrypt, the certificate with corresponding private key must be present in the user's certificate store. The public certificate can be specified as the SHA1 thumbprint (hash) of the certificate, or the base64 encoded certificate itself. For instance:

CERTIFICATE=HashID:28ac375635b82ca3e20a1c9422145bc93965dae7
CERTIFICATE=CertBlob:MIIC7TCCAdWgAw...pgpVgYpppr

Note: The base64 certificate data should not include any headers, footers, or whitespace.

The use of AND and OR operators are accepted in order to encrypt data for multiple parties or establish multiple conditions for decryption.

For more details about protection descriptors and accepted formats please refer to the Microsoft Documentation for Protection Descriptors

This setting is only applicable when use_cng is set to True.

This setting is not applicable on macOS.

Data Type

String

use_cng property (DPAPI Struct)

Whether to use CNG DPAPI.

Syntax

fn use_cng(&self ) -> Result<bool, IPWorksEncryptError> 
fn set_use_cng(&self, value : bool) ->  Option<IPWorksEncryptError>

Default Value

false

Remarks

The struct supports protecting data using either the classic DPAPI or CNG DPAPI implementation. When set to True the CNG DPAPI implementation is used. When set to False (default) the classic DPAPI implementation is used.

This setting is not applicable on macOS.

Data Type

bool

use_hex property (DPAPI Struct)

Whether input or output is hex encoded.

Syntax

fn use_hex(&self ) -> Result<bool, IPWorksEncryptError> 
fn set_use_hex(&self, value : bool) ->  Option<IPWorksEncryptError>

Default Value

false

Remarks

This property specifies whether the encrypted data is hex encoded.

If set to True, when protect is called the struct will perform the encryption as normal and then hex encode the output. output_message or output_file will hold hex encoded data.

If set to True, when unprotect is called the struct will expect input_message or input_file to hold hex encoded data. The struct will then hex decode the data and perform decryption as normal.

Data Type

bool

config method (DPAPI Struct)

Sets or retrieves a configuration setting.

Syntax

fn config(&self, configuration_string : &str) ->  Result<String, IPWorksEncryptError>

Remarks

config is a generic method available in every struct. It is used to set and retrieve configuration settings for the struct.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the struct, access to these internal properties is provided through the config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

on_error event (DPAPI Struct)

Fired when information is available about errors during data delivery.

Syntax

// DPAPIErrorEventArgs carries the DPAPI Error event's parameters.
pub struct DPAPIErrorEventArgs {
  fn error_code(&self) -> i32
  fn description(&self) -> &String
}

// DPAPIErrorEvent defines the signature of the DPAPI Error event's handler function.
pub trait DPAPIErrorEvent {
  fn on_error(&self, sender : DPAPI, e : &mut DPAPIErrorEventArgs);
}

impl <'a> DPAPI<'a> {
  pub fn on_error(&self) -> &'a dyn DPAPIErrorEvent;
  pub fn set_on_error(&mut self, value : &'a dyn DPAPIErrorEvent);
  ...
}

Remarks

The on_error event is fired in case of exceptional conditions during message processing. Normally the struct fails with an error.

The error_code parameter contains an error code, and the description parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

on_progress event (DPAPI Struct)

Fired as progress is made.

Syntax

// DPAPIProgressEventArgs carries the DPAPI Progress event's parameters.
pub struct DPAPIProgressEventArgs {
  fn bytes_processed(&self) -> i64

}

impl <'a> DPAPI<'a> {
  pub fn on_progress(&self) -> &'a dyn DPAPIProgressEvent;
  pub fn set_on_progress(&mut self, value : &'a dyn DPAPIProgressEvent);
  ...
}

Remarks

This event is fired automatically as data is processed by the struct.

The PercentProcessed parameter indicates the current status of the operation.

The BytesProcessed parameter holds the total number of bytes processed so far.

Config Settings (DPAPI Struct)

The struct accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the struct, access to these internal properties is provided through the config method.

DPAPI Config Settings

EscapeDescriptor: Whether to escape the protection descriptor.

This setting controls whether the protection_descriptor value is escaped when protect is called. When set to False (default) the value is passed exactly as provided to the underlying system libraries. When set to True the value is first escaped according to the escaping rules defined by Microsoft.

The default value of EscapeDescriptor is True.

This setting is only applicable when use_cng is set to True.

This setting is not applicable on macOS.

KeychainServiceName: Service name for the keychain on macOS.

This setting is used to specify the service name for the keychain on macOS. By default, nsoftware OSDP User Key is used as the service name for the user keychain. nsoftware OSDP System Key is used for the system keychain when UseSystemKeychain is set to True.

ProtectionFlags: Used to specify additional options.

Additional options are available to restrict or change the behavior of the protect and unprotect operations.

By default no additional settings are specified (the value is 0). You may set this property to the binary 'OR' of one or more of the following values:


1 (0x1)	CRYPTPROTECT_UI_FORBIDDEN	This flag is used for remote situations where presenting a user interface (UI) is not an option. When this flag is set and a UI is specified for either the protect or unprotect operation, the operation fails.
4 (0x4)	CRYPTPROTECT_LOCAL_MACHINE	When this flag is set, it associates the data encrypted with the current computer instead of with an individual user. This is only applicable when calling protect.
8 (0x8)	CRYPTPROTECT_CRED_SYNC	When this flag is used, no data is actually protected. Instead all MasterKeys are queried from disk, which will cause re-encryption in memory, presumably under a changed password. This is only applicable when calling protect.
16 (0x10)	CRYPTPROTECT_AUDIT	This flag causes DPAPI to generate an audit when this data is protected or unprotected. This is only applicable when calling protect.
64 (0x40)	CRYPTPROTECT_VERIFY_PROTECTION	If the protected data blob would be better protected under a new call to the internal protect function and this call succeeds, then GetLastError will return a CRYPT_I_NEW_PROTECTION_REQUIRED status code. This is only applicable when calling unprotect.
536870912 (0x20000000)	CRYPTPROTECT_SYSTEM	If data was protected with this flag set, then this flag must be set to unprotect the data.

This setting is not applicable when use_cng is set to True.

This setting is not applicable on macOS.

UseStreamMode: Whether to use the CNG streaming operations.

When set to True the struct will use the CNG streaming operations when protect and unprotect are called. When working with large amounts of data this can reduce the memory overhead during processing. Note that when enabled input_file and output_file should be used for optimal memory usage.

The default value of UseStreamMode is False.

This setting is only applicable when use_cng is set to True.

This setting is not applicable on macOS.

UseSystemKeychain: Whether to save the key and IV in the macOS System keychain.

When set to True, the key and IV will be saved in the macOS system keychain with the service name nsoftware OSDP System Key. Administrator privileges are required to use this config. This config is not supported on iOS.

The default value of UseSystemKeychain is False, and the key and IV are stored in the user keychain with the service name nsoftware OSDP User Key.

Base Config Settings

BuildInfo: Information about the product's build.

When queried, this setting will return a string containing information about the product's build.

CodePage: The system code page used for Unicode to Multibyte translations.

The default code page is Unicode UTF-8 (65001).

LicenseInfo: Information about the current license.

When queried, this setting will return a string containing information about the license this instance of a struct is using. It will return the following information:

Product: The product the license is for.
Product Key: The key the license was generated from.
License Source: Where the license was found (e.g., RuntimeLicense, License File).
License Type: The type of license installed (e.g., Royalty Free, Single Server).
Last Valid Build: The last valid build number for which the license will work.

MaskSensitiveData: Whether sensitive data is masked in log messages.

In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to true to mask sensitive data. The default is true.

UseInternalSecurityAPI: Whether or not to use the system security libraries or an internal implementation.

When set to false, the struct will use the system security libraries by default to perform cryptographic functions where applicable.

Setting this configuration setting to true tells the struct to use the internal implementation instead of using the system security libraries.

On Windows, this setting is set to false by default. On Linux/macOS, this setting is set to true by default.

To use the system security libraries for Linux, OpenSSL support must be enabled. For more information on how to enable OpenSSL, please refer to the OpenSSL Notes section.
