TrustedRoots Delphi DLL Reference Documentation

TrustedRoots

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.

Create/Dispose

var
myObject: HCkTrustedRoots;

begin
myObject := CkTrustedRoots_Create();

// ...

CkTrustedRoots_Dispose(myObject);
end;
function CkTrustedRoots_Create: HCkTrustedRoots; stdcall;

Creates an instance of the HCkTrustedRoots object and returns a handle (i.e. a Pointer). The handle is passed in the 1st argument for the functions listed on this page.

procedure CkTrustedRoots_Dispose(handle: HCkTrustedRoots); stdcall;

Objects created by calling CkTrustedRoots_Create must be freed by calling this method. A memory leak occurs if a handle is not disposed by calling this function.

Properties

DebugLogFilePath
procedure CkTrustedRoots_getDebugLogFilePath(objHandle: HCkTrustedRoots; outPropVal: HCkString); stdcall;
procedure CkTrustedRoots_putDebugLogFilePath(objHandle: HCkTrustedRoots; newPropVal: PWideChar); stdcall;
function CkTrustedRoots__debugLogFilePath(objHandle: HCkTrustedRoots): PWideChar; stdcall;

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.

See the notes about PWideChar memory ownership and validity.

LastErrorHtml
procedure CkTrustedRoots_getLastErrorHtml(objHandle: HCkTrustedRoots; outPropVal: HCkString); stdcall;
function CkTrustedRoots__lastErrorHtml(objHandle: HCkTrustedRoots): PWideChar; stdcall;

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.

See the notes about PWideChar memory ownership and validity.

top
LastErrorText
procedure CkTrustedRoots_getLastErrorText(objHandle: HCkTrustedRoots; outPropVal: HCkString); stdcall;
function CkTrustedRoots__lastErrorText(objHandle: HCkTrustedRoots): PWideChar; stdcall;

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.

See the notes about PWideChar memory ownership and validity.

top
LastErrorXml
procedure CkTrustedRoots_getLastErrorXml(objHandle: HCkTrustedRoots; outPropVal: HCkString); stdcall;
function CkTrustedRoots__lastErrorXml(objHandle: HCkTrustedRoots): PWideChar; stdcall;

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.

See the notes about PWideChar memory ownership and validity.

top
LastMethodSuccess
function CkTrustedRoots_getLastMethodSuccess(objHandle: HCkTrustedRoots): wordbool; stdcall;
procedure CkTrustedRoots_putLastMethodSuccess(objHandle: HCkTrustedRoots; newPropVal: wordbool); stdcall;

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.

top
NumCerts
function CkTrustedRoots_getNumCerts(objHandle: HCkTrustedRoots): Integer; stdcall;
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.

top
RejectSelfSignedCerts
function CkTrustedRoots_getRejectSelfSignedCerts(objHandle: HCkTrustedRoots): wordbool; stdcall;
procedure CkTrustedRoots_putRejectSelfSignedCerts(objHandle: HCkTrustedRoots; newPropVal: wordbool); stdcall;
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).

top
TrustSystemCaRoots
function CkTrustedRoots_getTrustSystemCaRoots(objHandle: HCkTrustedRoots): wordbool; stdcall;
procedure CkTrustedRoots_putTrustSystemCaRoots(objHandle: HCkTrustedRoots; newPropVal: wordbool); stdcall;
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.

VerboseLogging
function CkTrustedRoots_getVerboseLogging(objHandle: HCkTrustedRoots): wordbool; stdcall;
procedure CkTrustedRoots_putVerboseLogging(objHandle: HCkTrustedRoots; newPropVal: wordbool); stdcall;

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.

top
Version
procedure CkTrustedRoots_getVersion(objHandle: HCkTrustedRoots; outPropVal: HCkString); stdcall;
function CkTrustedRoots__version(objHandle: HCkTrustedRoots): PWideChar; stdcall;

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

See the notes about PWideChar memory ownership and validity.

Methods

Activate
function CkTrustedRoots_Activate(objHandle: HCkTrustedRoots): wordbool; stdcall;
Introduced in version 9.5.0.38

Activates this collection of trusted roots as the set of CA and self-signed root certificates that are to be trusted Chilkat-wide for PKCS7 signature validation and SSL/TLS server certificate validation.

Returns True for success, False for failure.

top
LoadCaCertsPem
function CkTrustedRoots_LoadCaCertsPem(objHandle: HCkTrustedRoots;
    path: PWideChar): wordbool; stdcall;
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)
function CkTrustedRoots_LoadCaCertsPemAsync(objHandle: HCkTrustedRoots;
    path: PWideChar): HCkTask; stdcall;
Introduced in version 9.5.0.38

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

Events

AbortCheck
function MyAbortCheck(): Integer; cdecl;
Introduced in version 9.5.0.82

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. Return True to abort; return False to continue (not abort)

PercentDone
function MyPercentDone(pctDone: Integer): Integer; cdecl;
Introduced in version 9.5.0.82

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.

Return True to abort; return False to continue (not abort)

ProgressInfo
procedure MyProgressInfo(name: PWideChar; value: PWideChar) cdecl;
Introduced in version 9.5.0.82

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
procedure MyTaskCompleted(task: HCkTask) cdecl;
Introduced in version 9.5.0.82

Called from the background thread when an asynchronous task completes.
