Contains a collection of certificates and PFX files saved in an XML format.
Importing the Chilkat ActiveX into Delphi
Important: When upgrading to a new version of Chilkat, make sure to re-imported ActiveX DLL into Delphi to regenerate the files described below.
Chilkat v9.5.*: If using Chilkat v9.5.*, then use "Chilkat_v9_5_0_TLB" instead of "Chilkat_TLB", and the DLLs are named ChilkatAx-9.5.0-win32.dll (or ChilkatAx-9.5.0-x64.dll).
Two things are required to use an ActiveX in Delphi:
- The ActiveX DLL needs to be registered via regsvr32 on the system where the Delphi application runs. See How To Register ActiveX DLLs for detailed information.
- See also: ActiveX Registration Tutorial
- The ActiveX component needs to be "imported". Use the Delphi Import Component Wizard to import the Chilkat type library. This creates the following files: Chilkat_TLB.pas and Chilkat_TLB.dcr. The Chilkat_TLB.pas should be added to your project.
To import the Chilkat type library, do the following:
- In the Delphi RAD Studio, select the menu item "Component" --> "Import a Type Library".
- Find "Chilkat ActiveX" in the list and select it. This will only appear in the list if the ChilkatAx-win32.dll (or ChilkatAx-x64.dll) has been registered w/ regsvr32.
- Check the "Generate Component Wrappers" checkbox.
- Select a directory where the unit files (.pas and .dcr) should be generated.
- Select "Create Unit" and then "Finish".
- Add the .pas to your Delphi project.
To use a Chilkat ActiveX object in your Delphi code, add "Chilkat_TLB" to the "uses" statement. For example:
uses Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics, Vcl.Controls, Vcl.Forms, Vcl.Dialogs, Vcl.StdCtrls, Chilkat_TLB;
Object Creation
var obj: TChilkatXmlCertVault; ... begin obj := TChilkatXmlCertVault.Create(Self); ... // When finished, free the object instance. obj.Free();
Properties
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.
LastBinaryResult
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 1. 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.
topLastErrorHtml
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.
topLastErrorText
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
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.
topLastMethodSuccess
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.
topLastStringResult
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.
LastStringResultLen
The length, in characters, of the string contained in the LastStringResult property.
topMasterPassword
The master password for the vault. Certificates are stored unencrypted, but private keys are stored 256-bit AES encrypted using the individual PFX passwords. The PFX passwords are stored 256-bit AES encrypted using the master password. The master password is required to acces any of the private keys stored within the XML vault.
topVerboseLogging
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.

Methods
AddCert
AddCertBinary
Adds a certificate to the XML vault from any binary format, such as DER.
Returns 1 for success, 0 for failure.
topAddCertChain
AddCertEncoded
Adds a certificate to the XML vault where certificate is passed directly from encoded bytes (such as Base64, Hex, etc.). The encoding is indicated by encoding.
Returns 1 for success, 0 for failure.
topAddCertFile
Adds a certificate to the XML vault.
Returns 1 for success, 0 for failure.
AddCertString
Adds a certificate from any string representation format such as PEM.
Returns 1 for success, 0 for failure.
AddPemFile
Adds the contents of a PEM file to the XML vault. The PEM file may be encrypted, and it may contain one or more certificates and/or private keys. The password is optional and only required if the PEM file contains encrypted content that requires a password.
Returns 1 for success, 0 for failure.
topAddPfx
AddPfxBinary
Adds a PFX to the XML vault where PFX is passed directly from in-memory binary bytes.
Returns 1 for success, 0 for failure.
topAddPfxEncoded
Adds a PFX to the XML vault where PFX is passed directly from encoded bytes (such as Base64, Hex, etc.). The encoding is indicated by encoding.
Returns 1 for success, 0 for failure.
topAddPfxFile
GetXml
Returns the contents of the cert vault as an XML string.
Returns a zero-length WideString on failure
