TrustedRoots Lianja Reference Documentation

TrustedRoots

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

loObject = createobject("CkTrustedRoots")

Properties

DebugLogFilePath As Character

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.

LastErrorHtml As Character (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.

LastErrorText As Character (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.

Concept of LastErrorText

LastErrorText Standard Information

LastErrorXml As Character (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.

LastMethodSuccess As Boolean

Introduced in version 9.5.0.52

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

NumCerts As Numeric (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.

TrustSystemCaRoots As Boolean

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 .T.. Set this property equal to .F. to prevent Chilkat from automatically trusting system-provided root CA certificates.

HTTP - Verify Server is a Trusted Root CA

VerboseLogging As Boolean

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

Version As Character (read-only)

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

Methods

Activate() As 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.

HTTP - Verify Server is a Trusted Root CA

AddCert(cert As CkCert) As Boolean

Introduced in version 9.5.0.41

Adds a certificate to the collection of trusted roots.

Use a Custom Set of Trusted Root Certificates

AddJavaKeyStore(keystore As CkJavaKeyStore) As Boolean

Introduced in version 9.5.0.44

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

Returns .T. for success, .F. for failure.

Load Certs from Java KeyStore into Trusted CA Roots

AddJavaKeyStoreAsync(keystore As CkJavaKeyStore) As CkTask

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 .F. on failure

How to Run an Asynchronous Task

Deactivate() As 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 .T. for success, .F. for failure.

GetCert(index As Numeric) As CkCert

Introduced in version 9.5.0.38

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

Returns .F. on failure

Load CA Cert Bundle into Trusted Roots

LoadCaCertsPem(path As Character) As 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.

Load CA Cert Bundle into Trusted Roots

LoadCaCertsPemAsync(path As Character) As CkTask

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 .F. on failure

How to Run an Asynchronous Task

SaveLastError(path As Character) As Boolean

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

Returns .T. for success, .F. for failure.
