CodeSign PureBasic Reference Documentation

CodeSign

Current Version: 10.1.2
Requires Chilkat Bundle License

A class for signing Windows executables and DLLs, and for verifying signed executables and DLLs. This is a Windows-only class. The class and functions will exist on non-Windows systems, but will be no-op functions (stubs) that simply return a failed status.

Object Creation

obj.i = CkCodeSign::ckCreate()

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

Properties

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

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
Declare.s ckLastErrorHtml(obj.i) ; (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
Declare.s ckLastErrorText(obj.i) ; (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.

LastErrorXml
Declare.s ckLastErrorXml(obj.i) ; (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
Declare.i ckLastMethodSuccess(obj.i)
Declare setCkLastMethodSuccess(obj.i, value.i)

Indicates the success or failure of the most recent method call: 1 means success, 0 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
UncommonOptions
Declare.s ckUncommonOptions(obj.i)
Declare setCkUncommonOptions(obj.i, value.s)
Introduced in version 9.5.0.97

This is a catch-all property to be used for uncommon needs. This property defaults to the empty string and should typically remain empty.

Can be set to a list of the following comma separated keywords:

  • "codesign-allow-expired-cert" - Don't fail authenticode signature validation because the signing certificate is expired.

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.

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

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

Methods

AddSignature
Declare.i ckAddSignature(obj.i, path.s, cert.i, options.i)
Introduced in version 9.5.0.97

Authenticode signs a DLL or EXE.

Returns 1 for success, 0 for failure.

More Information and Examples
Authenticode Sign an Executable (EXE) or DLL
top
AddSignatureAsync (1)
Declare.i ckAddSignatureAsync(obj.i, path.s, cert.i, options.i)
Introduced in version 9.5.0.97

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

Returns 0 on failure

top
GetSignerCert
Declare.i ckGetSignerCert(obj.i, cert.i)
Introduced in version 10.0.1

This method retrieves the signer certificate after calling VerifySignature. If successful and the signer certificate is fully available, cert will contain the certificate.

Returns 1 for success, 0 for failure.

top
RemoveSignature
Declare.i ckRemoveSignature(obj.i, path.s)
Introduced in version 9.5.0.97

Removes the authenticode signature of a Windows executable or DLL. The path to the executable/DLL is passed in path.

Returns 1 for success, 0 for failure.

More Information and Examples
Remove the Authenticode Signature from an EXE or DLL
top
VerifySignature
Declare.i ckVerifySignature(obj.i, path.s, sigInfo.i)
Introduced in version 9.5.0.97

Verifies the signature of a Windows executable or DLL. The path to the executable/DLL is passed in path. Information about the signature is returned in sigInfo. Returns 1 if the signature is verified indicating the EXE or DLL can be trusted. Otherwise returns 0.

Returns 1 for success, 0 for failure.
