CodeSign

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.

This property is mainly used in SQL Server stored procedures to retrieve binary data from the last method call that returned binary data. It is only accessible if Chilkat.Global.KeepBinaryResult is set to true. This feature allows for the retrieval of large varbinary results in an SQL Server environment, which has restrictions on returning large data via method calls, though temp tables can handle binary properties.

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.

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.

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.

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. Note: This property does not apply to methods that return integer values or to boolean-returning methods where the boolean does not indicate success or failure.

In SQL Server stored procedures, this property holds the string return value of the most recent method call that returns a string. It is accessible only when Chilkat.Global.KeepStringResult is set to TRUE. SQL Server has limitations on string lengths returned from methods and properties, but temp tables can be used to access large strings.

The length, in characters, of the string contained in the LastStringResult property.

Provides a comma-separated list of specialized compatibility or validation options. The default is an empty string, which is appropriate for normal use.

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.

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

Adds a Microsoft Authenticode signature to the Windows executable or DLL specified by path. The file is modified in place. cert supplies the code-signing certificate and must provide access to its associated private key. options supplies the signing configuration as JSON.

Common options options include:

{
  "hashAlg": "sha256",
  "timestampToken": {
    "enabled": true,
    "tsaUrl": "http://timestamp.example.com",
    "requestTsaCert": true,
    "hashAlg": "sha256"
  }
}

Returns true for success, false for failure.

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

Returns null on failure

Retrieves the X.509 signer certificate discovered by the most recent call to VerifySignature on this CodeSign object. If the certificate is fully available, cert is loaded with it and the method returns true. Otherwise, the method returns false.

The returned object contains the public certificate only; it does not provide the signer's private key. Call this method after VerifySignature and use the same CodeSign instance.

Returns true for success, false for failure.

Removes the embedded Authenticode signature from the Windows executable or DLL specified by path. The file is modified in place. Returns true if the signature is successfully removed; otherwise returns false.

Returns true for success, false for failure.

Verifies the embedded Microsoft Authenticode signature of the Windows executable or DLL specified by path. Structured information about the signature, signer, certificate chain, digest algorithms, timestamp, and validation result is written to sigInfo.

Returns true when the signature satisfies the applicable Authenticode validation checks under the current Windows trust configuration. This includes confirming that the signed portions of the file have not changed and evaluating the signing certificate and timestamp information, as applicable. An unsigned file or a signature that does not validate causes the method to return false. Inspect sigInfo and LastErrorText for details.

Returns true for success, false for failure.
