TrustedRoots Unicode C Reference Documentation
TrustedRoots
Current Version: 10.1.2
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
HCkTrustedRootsW instance = CkTrustedRootsW_Create(); // ... CkTrustedRootsW_Dispose(instance);
Creates an instance of the HCkTrustedRootsW object and returns a handle ("void *" pointer). The handle is passed in the 1st argument for the functions listed on this page.
Objects created by calling CkTrustedRootsW_Create must be freed by calling this method. A memory leak occurs if a handle is not disposed by calling this function. Also, any handle returned by a Chilkat "C" function must also be freed by the application by calling the appropriate Dispose method, such as CkTrustedRootsW_Dispose.
Callback Functions
Provides the opportunity for a method call to be aborted. If TRUE is returned, the operation in progress is aborted. Return FALSE to allow the current method call to continue. This callback function is called periodically based on the value of the HeartbeatMs property. (If HeartbeatMs is 0, then no callbacks are made.) As an example, to make 5 AbortCheck callbacks per second, set the HeartbeatMs property equal to 200.
Provides the percentage completed for any method that involves network communications or time-consuming processing (assuming it is a method where a percentage completion can be measured). This callback is only called when it is possible to know a percentage completion, and when it makes sense to express the operation as a percentage completed. The pctDone argument will have a value from 1 to 100. For methods that complete very quickly, the number of PercentDone callbacks will vary, but the final callback should have a value of 100. For long running operations, no more than one callback per percentage point will occur (for example: 1, 2, 3, ... 98, 99, 100).
This callback counts as an AbortCheck callback, and takes the place of the AbortCheck event when it fires.
The return value indicates whether the method call should be aborted, or whether it should proceed. Return TRUE to abort, and FALSE to proceed.
This is a general callback that provides name/value information about what is happening at certain points during a method call. To see the information provided in ProgressInfo callbacks, if any, write code to handle this event and log the name/value pairs. Most are self-explanatory.
Called in the background thread when an asynchronous task completes. (Note: When an async method is running, all callbacks are in the background thread.)
Properties
DebugLogFilePath
void CkTrustedRootsW_putDebugLogFilePath(HCkTrustedRootsW cHandle, const wchar_t *newVal);
const wchar_t *CkTrustedRootsW_debugLogFilePath(HCkTrustedRootsW cHandle);
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.
LastErrorHtml
const wchar_t *CkTrustedRootsW_lastErrorHtml(HCkTrustedRootsW cHandle);
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.
topLastErrorText
const wchar_t *CkTrustedRootsW_lastErrorText(HCkTrustedRootsW cHandle);
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.
LastErrorXml
const wchar_t *CkTrustedRootsW_lastErrorXml(HCkTrustedRootsW cHandle);
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.
topLastMethodSuccess
void CkTrustedRootsW_putLastMethodSuccess(HCkTrustedRootsW cHandle, 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.
topNumCerts
The number of certificates contained within this object.
This is the number of certificates explicitly added by the methods AddCert, AddJavaKeyStore, and LoadCaCertsPem.
topRejectSelfSignedCerts
void CkTrustedRootsW_putRejectSelfSignedCerts(HCkTrustedRootsW cHandle, BOOL newVal);
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).
topTrustSystemCaRoots
void CkTrustedRootsW_putTrustSystemCaRoots(HCkTrustedRootsW cHandle, BOOL newVal);
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
void CkTrustedRootsW_putVerboseLogging(HCkTrustedRootsW cHandle, 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.
topVersion
const wchar_t *CkTrustedRootsW_version(HCkTrustedRootsW cHandle);
Methods
Activate
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.
AddCert
AddJavaKeyStore
Adds the trusted certificates from a Java key store to the collection of trusted roots.
Returns TRUE for success, FALSE for failure.
AddJavaKeyStoreAsync (1)
Creates an asynchronous task to call the AddJavaKeyStore method with the arguments provided.
Returns NULL on failure
topDeactivate
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.
topGetCert
Returns the Nth cert contained within this object. The 1st certificate is at index 0.
Returns NULL on failure
LoadCaCertsPem
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)
Creates an asynchronous task to call the LoadCaCertsPem method with the arguments provided.
Returns NULL on failure
