TrustedRoots C++ Reference Documentation

CkTrustedRoots

Current Version: 11.1.0

Used to set and manage the CA root certificates trusted by your application. This applies to PKCS7 (S/MIME) signature validation and SSL/TLS server certificates.

Object Creation

// Local variable on the stack
CkTrustedRoots obj;

// Dynamically allocate/delete
CkTrustedRoots *pObj = new CkTrustedRoots();
// ...
delete pObj;

Properties

DebugLogFilePath

void get_DebugLogFilePath(CkString &str);
const char *debugLogFilePath(void);
void put_DebugLogFilePath(const char *ansiOrUtf8Str);

If set to a file path, this property logs the LastErrorText of each Chilkat method or property call to the specified file. This logging helps identify the context and history of Chilkat calls leading up to any crash or hang, aiding in debugging.

Enabling the VerboseLogging property provides more detailed information. This property is mainly used for debugging rare instances where a Chilkat method call causes a hang or crash, which should generally not happen.

Possible causes of hangs include:

A timeout property set to 0, indicating an infinite timeout.
A hang occurring within an event callback in the application code.
An internal bug in the Chilkat code causing the hang.

More Information and Examples

LastErrorHtml

void get_LastErrorHtml(CkString &str);
const char *lastErrorHtml(void);

Provides HTML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.

LastErrorText

void get_LastErrorText(CkString &str);
const char *lastErrorText(void);

Provides plain text information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.

More Information and Examples

Concept of LastErrorText LastErrorText Standard Information

LastErrorXml

void get_LastErrorXml(CkString &str);
const char *lastErrorXml(void);

Provides XML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.

LastMethodSuccess

bool get_LastMethodSuccess(void);
void put_LastMethodSuccess(bool newVal);

Indicates the success or failure of the most recent method call: true means success, false means failure. This property remains unchanged by property setters or getters. This method is present to address challenges in checking for null or Nothing returns in certain programming languages.

NumCerts

int get_NumCerts(void);

Introduced in version 9.5.0.38

The number of certificates contained within this object.

This is the number of certificates explicitly added by the methods AddCert, AddJavaKeyStore, and LoadCaCertsPem.

RejectSelfSignedCerts

bool get_RejectSelfSignedCerts(void);
void put_RejectSelfSignedCerts(bool newVal);

Introduced in version 9.5.0.80

Indicates whether all self-signed certificates are to be rejected in SSL/TLS connections. The default value of this property is false.

Note: This is for the case where the server certificate chain of authentication is 1 certificate long (i.e. the TLS server certificate itself is self-signed).

TrustSystemCaRoots

bool get_TrustSystemCaRoots(void);
void put_TrustSystemCaRoots(bool newVal);

Introduced in version 9.5.0.41

Indicates whether the operating system's CA root certificates are automatically trusted.

On a Windows operating system, this would be the registry-based CA certificate stores. On a Linux system, this could be /etc/ssl/certs/ca-certificates.crt, if it exists. The default value is true. Set this property equal to false to prevent Chilkat from automatically trusting system-provided root CA certificates.

More Information and Examples

HTTP - Verify Server is a Trusted Root CA

Utf8

bool get_Utf8(void);
void put_Utf8(bool newVal);

When set to true, all const char * arguments and return values are interpreted as UTF-8 strings. When set to false, they are interpreted as ANSI strings.

In Chilkat v11.0.0 and later, the default value is true. Before v11.0.0, it was false.

VerboseLogging

bool get_VerboseLogging(void);
void put_VerboseLogging(bool newVal);

If set to true, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is false. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.

Version

void get_Version(CkString &str);
const char *version(void);

Version of the component/library, such as "10.1.0"

AddCert

bool AddCert(CkCert &cert);

Introduced in version 9.5.0.41

Adds a certificate to the collection of trusted roots.

AddJavaKeyStore

bool AddJavaKeyStore(CkJavaKeyStore &keystore);

Introduced in version 9.5.0.44

Adds the trusted certificates from a Java key store to the collection of trusted roots.

Returns true for success, false for failure.

More Information and Examples

AddJavaKeyStoreAsync ⁽¹⁾

CkTask *AddJavaKeyStoreAsync(CkJavaKeyStore &keystore);

Introduced in version 9.5.0.44

Creates an asynchronous task to call the AddJavaKeyStore method with the arguments provided.

Note: Async method event callbacks happen in the background thread. Accessing and updating UI elements existing in the main thread may require special considerations.

Note: The application is responsible for deleting (via the C++ delete operator) the object returned by this method.

Returns NULL on failure

CertAt

bool CertAt(int index, CkCert &cert);

Introduced in version 11.0.0

Returns in cert the Nth cert contained within this object. The 1st certificate is at index 0.

Returns true for success, false for failure.

Deactivate

bool Deactivate(void);

Introduced in version 9.5.0.40

Deactivates a previous set of activated trusted roots so that all roots / self-signed certificates are implicitly trusted.

Returns true for success, false for failure.

LoadCaCertsPem

bool LoadCaCertsPem(const char *path);

Introduced in version 9.5.0.38

Loads a CA bundle in PEM format. This is a file containing CA root certificates that are to be trusted. An example of one such file is the CA certs from mozilla.org exported to a cacert.pem file by the mk-ca-bundle tool located here: http://curl.haxx.se/docs/caextract.html.

Note: This can also be called to load the /etc/ssl/certs/ca-certificates.crt file on Linux systems.

LoadCaCertsPemAsync ⁽¹⁾

CkTask *LoadCaCertsPemAsync(const char *path);

Introduced in version 9.5.0.38

Creates an asynchronous task to call the LoadCaCertsPem method with the arguments provided.

Note: Async method event callbacks happen in the background thread. Accessing and updating UI elements existing in the main thread may require special considerations.

Note: The application is responsible for deleting (via the C++ delete operator) the object returned by this method.

Returns NULL on failure

LoadTaskCaller

bool LoadTaskCaller(CkTask &task);

Introduced in version 9.5.0.80

Loads the caller of the task's async method.

Returns true for success, false for failure.

Events

To implement an event callback, your application would define and implement a class that inherits from CkBaseProgress. Your application can implement methods to override some or all of the default/empty method implementations of the CkBaseProgress base class.

For example:

  CkTrustedRoots trustedroots;

  MyTrustedRootsProgress callbackObj;

  trustedroots.put_EventCallbackObject(&callbackObj);

MyTrustedRootsProgress example:

#include "CkBaseProgress.h"

class MyTrustedRootsProgress : public CkBaseProgress {

  public:
    MyTrustedRootsProgress();
    virtual ~MyTrustedRootsProgress();

    void AbortCheck(bool  *abort);

    void PercentDone(int pctDone, bool  *abort);

    void ProgressInfo(const char *name, const char *value);

    void TaskCompleted(CkTask &task);

};

AbortCheck

void AbortCheck(bool *abort);

Enables a method call to be aborted by triggering the AbortCheck event at intervals defined by the HeartbeatMs property. If HeartbeatMs is set to its default value of 0, no events will occur. For instance, set HeartbeatMs to 200 to trigger 5 AbortCheck events per second.

More Information and Examples

Chilkat Event Callback Examples

PercentDone

void PercentDone(int pctDone, bool *abort);

This provides the percentage completion for any method involving network communications or time-consuming processing, assuming the progress can be measured as a percentage. This event is triggered only when it's possible and logical to express the operation's progress as a percentage. The pctDone argument will range from 1 to 100. For methods that finish quickly, the number of PercentDone callbacks may vary, but the final callback will have pctDone equal to 100. For longer operations, callbacks will not exceed one per percentage point (e.g., 1, 2, 3, ..., 98, 99, 100).

The PercentDone callback also acts as an AbortCheck event. For fast methods where PercentDone fires, an AbortCheck event may not trigger since the PercentDone callback already provides an opportunity to abort. For longer operations, where time between PercentDone callbacks is extended, AbortCheck callbacks enable more responsive operation termination.

To abort the operation, set the abort output argument to true. This will cause the method to terminate and return a failure status or corresponding failure value.

Chilkat Event Callback Examples

ProgressInfo

void ProgressInfo(const char *name, const char *value);

This event callback provides tag name/value pairs that detail what occurs during a method call. To discover existing tag names, create code to handle the event, emit the pairs, and review them. Most tag names are self-explanatory.

TaskCompleted

void TaskCompleted(CkTask &task);

Called from the background thread when an asynchronous task completes.
