CodeSign PureBasic Reference Documentation

CodeSign

Current Version: 10.0.0
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, 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
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)

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.

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 "9.5.0.94"

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. (Async methods are available starting in Chilkat v9.5.0.52.)

Returns 0 on 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.
