TrustedRoots Python 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.

Object Creation

obj = chilkat2.TrustedRoots()

Properties

DebugLogFilePath
string DebugLogFilePath

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.

More Information and Examples
top
LastErrorHtml
string LastErrorHtml (read-only)

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.

top
LastErrorText
string LastErrorText (read-only)

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.

top
LastErrorXml
string LastErrorXml (read-only)

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.

top
LastMethodSuccess
bool LastMethodSuccess

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
int NumCerts (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
RejectSelfSignedCerts
bool RejectSelfSignedCerts
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
bool TrustSystemCaRoots
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.

More Information and Examples
top
VerboseLogging
bool VerboseLogging

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
string Version (read-only)

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

Methods

Activate
bool Activate()
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
bool AddCert(Cert cert)
Introduced in version 9.5.0.41

Adds a certificate to the collection of trusted roots.

top
AddJavaKeyStore
bool AddJavaKeyStore(JavaKeyStore keystore)
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)
Task AddJavaKeyStoreAsync(JavaKeyStore keystore)
Introduced in version 9.5.0.44

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

Returns None on failure

top
Deactivate
bool Deactivate()
Introduced in version 9.5.0.40

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.

top
GetCert
Cert GetCert(int index)
Introduced in version 9.5.0.38

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

Returns None on failure

More Information and Examples
top
LoadCaCertsPem
bool LoadCaCertsPem(string path)
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.

More Information and Examples
top
LoadCaCertsPemAsync (1)
Task LoadCaCertsPemAsync(string path)
Introduced in version 9.5.0.38

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

Returns None on failure

top
LoadTaskCaller
bool LoadTaskCaller(Task task)
Introduced in version 9.5.0.80

Loads the caller of the task's async method.

Returns True for success, False for failure.
