TrustedRoots

Current Version: 9.5.0.73

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.

Properties

DebugLogFilePath
Function ComDebugLogFilePath Returns String
Procedure Set ComDebugLogFilePath String value

If set to a file path, causes each Chilkat method or property call to automatically append it's LastErrorText to the specified log file. The information is appended such that if a hang or crash occurs, it is possible to see the context in which the problem occurred, as well as a history of all Chilkat calls up to the point of the problem. The VerboseLogging property can be set to provide more detailed information.

This property is typically used for debugging the rare cases where a Chilkat method call hangs or generates an exception that halts program execution (i.e. crashes). A hang or crash should generally never happen. The typical causes of a hang are:

  1. a timeout related property was set to 0 to explicitly indicate that an infinite timeout is desired,
  2. the hang is actually a hang within an event callback (i.e. it is a hang within the application code), or
  3. there is an internal problem (bug) in the Chilkat code that causes the hang.

LastBinaryResult
Function ComLastBinaryResult Returns Variant
Introduced in version 9.5.0.52

The binary data returned by the last (binary data returning) method called. Only available if Chilkat.Global.KeepBinaryResult is set to True. This provides a means for obtaining large varbinary results in the SQL Server environment (where limitations exist in getting large amounts of data returned by method calls, but where temp tables can be used for binary properties).

top
LastErrorHtml
Function ComLastErrorHtml Returns String

Provides information in HTML format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

top
LastErrorText
Function ComLastErrorText Returns String

Provides information in plain-text format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

top
LastErrorXml
Function ComLastErrorXml Returns String

Provides information in XML format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

top
LastMethodSuccess
Function ComLastMethodSuccess Returns Boolean
Procedure Set ComLastMethodSuccess Boolean value
Introduced in version 9.5.0.52

Indicate whether the last method call succeeded or failed. A value of True indicates success, a value of False indicates failure. This property is automatically set for method calls. It is not modified by property accesses. The property is automatically set to indicate success for the following types of method calls:

  • Any method that returns a string.
  • Any method returning a Chilkat object, binary bytes, or a date/time.
  • Any method returning a standard boolean status value where success = True and failure = False.
  • Any method returning an integer where failure is defined by a return value less than zero.

Note: Methods that do not fit the above requirements will always set this property equal to True. For example, a method that returns no value (such as a "void" in C++) will technically always succeed.

top
LastStringResult
Function ComLastStringResult Returns String
Introduced in version 9.5.0.52

The string return value of the last (string returning) method called. Only available if Chilkat.Global.KeepStringResult is set to True. This provides a means for obtaining large string results in the SQL Server environment (where limitations exist in getting long strings returned by method calls, but where temp tables can be used for string properties).

top
LastStringResultLen
Function ComLastStringResultLen Returns Integer
Introduced in version 9.5.0.53

The length, in characters, of the string contained in the LastStringResult property.

top
NumCerts
Function ComNumCerts Returns Integer
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
TrustSystemCaRoots
Function ComTrustSystemCaRoots Returns Boolean
Procedure Set ComTrustSystemCaRoots Boolean value
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 ComVerboseLogging Returns Boolean
Procedure Set ComVerboseLogging Boolean value

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
Function ComVersion Returns String

Version of the component/library, such as "9.5.0.63"

Methods

Activate
Function ComActivate Returns Boolean
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.

More Information and Examples
top
AddCert
Function ComAddCert cComChilkatCert cert Returns Boolean
Introduced in version 9.5.0.41

Adds a certificate to the collection of trusted roots.

More Information and Examples
top
AddJavaKeyStore
Function ComAddJavaKeyStore cComChilkatJavaKeyStore keystore Returns Boolean
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.

top
AddJavaKeyStoreAsync (1)
Function ComAddJavaKeyStoreAsync cComChilkatJavaKeyStore keystore Returns cComChilkatTask
Introduced in version 9.5.0.44

Creates an asynchronous task to call the AddJavaKeyStore method with the arguments provided. (Async methods are available starting in Chilkat v9.5.0.52.)

Returns null on failure

top
Deactivate
Function ComDeactivate Returns Boolean
Introduced in version 9.5.0.40

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

Returns True for success, False for failure.

top
GetCert
Function ComGetCert Integer index Returns cComChilkatCert
Introduced in version 9.5.0.38

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

Returns null on failure

LoadCaCertsPem
Function ComLoadCaCertsPem String path Returns Boolean
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 ComLoadCaCertsPemAsync String path Returns cComChilkatTask
Introduced in version 9.5.0.38

Creates an asynchronous task to call the LoadCaCertsPem method with the arguments provided. (Async methods are available starting in Chilkat v9.5.0.52.)

Returns null on failure
