CodeSign PHP ActiveX Reference Documentation
CodeSign
Current Version: 10.1.0
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
Chilkat v10.0.0 or greater:
$obj = new COM("Chilkat.CodeSign");
Chilkat v9.5.0.*:
$obj = new COM("Chilkat_9_5_0.CodeSign");
Properties
DebugLogFilePath
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:
- a timeout related property was set to 0 to explicitly indicate that an infinite timeout is desired,
- the hang is actually a hang within an event callback (i.e. it is a hang within the application code), or
- there is an internal problem (bug) in the Chilkat code that causes the hang.
LastBinaryResult
The binary data returned by the last (binary data returning) method called. Only available if Chilkat.Global.KeepBinaryResult is set to true. This provides a means for obtaining large varbinary results in the SQL Server environment (where limitations exist in getting large amounts of data returned by method calls, but where temp tables can be used for binary properties).
topLastErrorHtml
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.
topLastErrorText
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.
LastErrorXml
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.
topLastMethodSuccess
Indicate whether the last method call succeeded or failed. A value of true indicates success, a value of false 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 = true and failure = false.
- 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 true. For example, a method that returns no value (such as a "void" in C++) will technically always succeed.
topLastStringResult
The string return value of the last (string returning) method called. Only available if Chilkat.Global.KeepStringResult is set to true. This provides a means for obtaining large string results in the SQL Server environment (where limitations exist in getting long strings returned by method calls, but where temp tables can be used for string properties).
LastStringResultLen
The length, in characters, of the string contained in the LastStringResult property.
topUncommonOptions
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.
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.

Methods
AddSignature
Authenticode signs a DLL or EXE.
Returns true for success, false for failure.
AddSignatureAsync (1)
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 null on failure
topGetSignerCert
This method retrieves the signer certificate after calling VerifySignature. If successful and the signer certificate is fully available, cert will contain the certificate.
Returns true for success, false for failure.
topRemoveSignature
Removes the authenticode signature of a Windows executable or DLL. The path to the executable/DLL is passed in path.
Returns true for success, false for failure.
VerifySignature
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 true if the signature is verified indicating the EXE or DLL can be trusted. Otherwise returns false.
Returns true for success, false for failure.
