TrustedRoots PureBasic Reference Documentation

TrustedRoots

Current Version: 9.5.0.75

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

obj.i = CkTrustedRoots::ckCreate()

; Make sure to dispose of the object when finished like this:
CkTrustedRoots::ckDispose(obj);

Properties

DebugLogFilePath
Declare.s ckDebugLogFilePath(obj.i)
Declare setCkDebugLogFilePath(obj.i, value.s)

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.

top
LastErrorHtml
Declare.s ckLastErrorHtml(obj.i) ; (read-only)

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
Declare.s ckLastErrorText(obj.i) ; (read-only)

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
Declare.s ckLastErrorXml(obj.i) ; (read-only)

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
Declare.i ckLastMethodSuccess(obj.i)
Declare setCkLastMethodSuccess(obj.i, value.i)
Introduced in version 9.5.0.52

Indicate whether the last method call succeeded or failed. A value of 1 indicates success, a value of 0 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 = 1 and failure = 0.
  • 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 1. For example, a method that returns no value (such as a "void" in C++) will technically always succeed.

top
NumCerts
Declare.i ckNumCerts(obj.i) ; (read-only)
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
Declare.i ckTrustSystemCaRoots(obj.i)
Declare setCkTrustSystemCaRoots(obj.i, value.i)
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 1. Set this property equal to 0 to prevent Chilkat from automatically trusting system-provided root CA certificates.

More Information and Examples
top
VerboseLogging
Declare.i ckVerboseLogging(obj.i)
Declare setCkVerboseLogging(obj.i, value.i)

If set to 1, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is 0. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.

Version
Declare.s ckVersion(obj.i) ; (read-only)

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

Methods

Activate
Declare.i ckActivate(obj.i)
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
Declare.i ckAddCert(obj.i, cert.i)
Introduced in version 9.5.0.41

Adds a certificate to the collection of trusted roots.

More Information and Examples
top
AddJavaKeyStore
Declare.i ckAddJavaKeyStore(obj.i, keystore.i)
Introduced in version 9.5.0.44

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

Returns 1 for success, 0 for failure.

top
AddJavaKeyStoreAsync (1)
Declare.i ckAddJavaKeyStoreAsync(obj.i, keystore.i)
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 0 on failure

top
Deactivate
Declare.i ckDeactivate(obj.i)
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 1 for success, 0 for failure.

top
GetCert
Declare.i ckGetCert(obj.i, index.l)
Introduced in version 9.5.0.38

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

Returns 0 on failure

LoadCaCertsPem
Declare.i ckLoadCaCertsPem(obj.i, path.s)
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.

top
LoadCaCertsPemAsync (1)
Declare.i ckLoadCaCertsPemAsync(obj.i, path.s)
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 0 on failure

top
SaveLastError
Declare.i ckSaveLastError(obj.i, path.s)

Saves the last-error information (the contents of LastErrorXml) to an XML formatted file.

Returns 1 for success, 0 for failure.
