Current Version: 9.5.0.73

Digital certificate component / class

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.

Two things are required to use an ActiveX in Delphi:

  1. 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.
  2. See also: ActiveX Registration Tutorial
  3. 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_v9_5_0_TLB.pas and Chilkat_v9_5_0_TLB.dcr. The Chilkat_v9_5_0_TLB.pas should be added to your project.

To import the Chilkat type library, do the following:

  1. In the Delphi RAD Studio, select the menu item "Component" --> "Import a Type Library".
  2. Find "Chilkat ActiveX v9.5.0" in the list and select it. This will only appear in the list if the ChilkatAx-9.5.0-win32.dll (or ChilkatAx-9.5.0-x64.dll) has been registered w/ regsvr32.
  3. Check the "Generate Component Wrappers" checkbox.
  4. Select a directory where the unit files (.pas and .dcr) should be generated.
  5. Select "Create Unit" and then "Finish".
  6. Add the .pas to your Delphi project.

To use a Chilkat ActiveX object in your Delphi code, add "Chilkat_v9_5_0_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_v9_5_0_TLB;

Object Creation

var
obj: TChilkatCert;
...
begin
obj := TChilkatCert.Create(Self);
...
// When finished, free the object instance.
obj.Free();

Properties

AuthorityKeyId
property AuthorityKeyId: WideString readonly
Introduced in version 9.5.0.40

The authority key identifier of the certificate in base64 string format. This is only present if the certificate contains the extension OID 2.5.29.35.

top
AvoidWindowsPkAccess
property AvoidWindowsPkAccess: Integer

Applies only when running on a Microsoft Windows operating system. If 1, then any method that returns a certificate will not try to also access the associated private key, assuming one exists. This is useful if the certificate was installed with high-security such that a private key access would trigger the Windows OS to display a security warning dialog. The default value of this property is 0.

top
CertVersion
property CertVersion: Integer readonly

The version of the certificate (1, 2, or 3). A value of 0 indicates an error -- the most likely cause being that the certificate object is empty (i.e. was never loaded with a certificate). Note: This is not the version of the software, it is the version of the X.509 certificate object. The version of the Chilkat certificate software is indicated by the Version property.

top
CspName
property CspName: WideString readonly

(Relevant only when running on a Microsoft Windows operating system.) If the HasKeyContainer property is 1, then the certificate is linked to a key container and this property contains the name of the associated CSP (cryptographic service provider). When a certificate is linked to a key container , the following properties will provide information about the key container and private key: CspName, KeyContainerName, MachineKeyset, and Silent.

top
DebugLogFilePath
property DebugLogFilePath: WideString

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.

top

When a certificate is linked to a key container , the following properties will provide information about the key container and private key: CspName, KeyContainerName, MachineKeyset, and Silent.

top
LastBinaryResult
property LastBinaryResult: OleVariant readonly
Introduced in version 9.5.0.52

The binary data returned by the last (binary data returning) method called. Only available if Chilkat.Global.KeepBinaryResult is set to 1. 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).

top
LastErrorHtml
property LastErrorHtml: WideString readonly

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

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
property LastMethodSuccess: Integer
Introduced in version 9.5.0.52

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.

top
LastStringResult
property LastStringResult: WideString readonly
Introduced in version 9.5.0.52

The string return value of the last (string returning) method called. Only available if Chilkat.Global.KeepStringResult is set to 1. 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).

top
LastStringResultLen
property LastStringResultLen: Integer readonly
Introduced in version 9.5.0.53

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

top
MachineKeyset
property MachineKeyset: Integer readonly

If 1, the key container is within the machine keyset. If 0, it's in the user's keyset.

When a certificate is linked to a key container , the following properties will provide information about the key container and private key: CspName, KeyContainerName, MachineKeyset, and Silent.

top
OcspUrl
property OcspUrl: WideString readonly

If present in the certificate's extensions, returns the OCSP URL of the certificate. (The Online Certificate Status Protocol (OCSP) is an Internet protocol used for obtaining the revocation status of an X.509 digital certificate.)

top
PrivateKeyExportable
property PrivateKeyExportable: Integer readonly

(Relevant only when running on a Microsoft Windows operating system.) Indicates whether the private key was installed with security settings that allow it to be re-exported.

top
Revoked
property Revoked: Integer readonly

1 if the certificate or any certificate in the chain of authority has been revoked. This information is not available when running on Windows 95/98 computers. Note: If this property is 0, it could mean that it was not able to check the revocation status. Because of this uncertainty, a CheckRevoked method has been added. It returns an integer indicating one of three possible states: 1 (revoked) , 0 (not revoked), -1 (unable to check revocation status).

top
Rfc822Name
property Rfc822Name: WideString readonly

The RFC-822 name of the certificate. (Also known as the Subject Alternative Name.)

top
Silent
property Silent: Integer readonly

(Relevant only when running on a Microsoft Windows operating system.) If the HasKeyContainer property is 1, then the certificate is linked to a key container and this property indicates whether accessing the private key will cause the operating system to launch an interactive warning dialog. If 0 a warning dialog will be displayed. If 1 then private key accesses are silent.

When a certificate is linked to a key container , the following properties will provide information about the key container and private key: CspName, KeyContainerName, MachineKeyset, and Silent.

top
TrustedRoot
property TrustedRoot: Integer readonly

Returns 1 if the certificate has a trusted root authority, otherwise returns 0.

Note: As of version 9.5.0.41, the notion of what your application deems as trusted becomes more specific. The TrustedRoots class/object was added in v9.5.0.0. Prior to this, a certificate was considered to be anchored by a trusted root if the certificate chain could be established to a root (self-signed) certificate, AND if the root certificate was located somewhere in the Windows registry-based certificate stores. There are two problems with this: (1) it's a Windows-only solution. This property would always return 0 on non-Windows systems, and (2) it might be considered not a strong enough set of conditions for trusting a root certificate.

As of version 9.5.0.41, this property pays attention to the new TrustedRoots class/object, which allows for an application to specificallly indicate which root certificates are to be trusted. Certificates may be added to the TrustedRoots object via the LoadCaCertsPem or AddCert methods, and then activated by calling the TrustedRoots.Activate method. The activated trusted roots are deemed to be trusted in any Chilkat API method/property that needs to make this determination. In addition, the TrustedRoots object has a property named TrustSystemCaRoots, which defaults to 1, which allows for backward compatibility. It will trust CA certificates stored in the Windows registry-based certificate stores, or if on Linux, will trust certificates found in /etc/ssl/certs/ca-certificates.crt.

top
ValidFromStr
property ValidFromStr: WideString readonly

The date (in RFC822 string format) that this certificate becomes (or became) valid. It is a GMT/UTC date that is returned.

top

The date (in RFC822 string format) that this certificate becomes (or became) invalid. It is a GMT/UTC date that is returned.

top
VerboseLogging
property VerboseLogging: Integer

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
property Version: WideString readonly

GetCertChain
function GetCertChain(): TChilkatCertChain;
Introduced in version 9.5.0.40

Returns a certficate chain object containing all the certificates (including this one), in the chain of authentication to the trusted root (if possible).

The UseCertVault method can be called to provide additional certificates that might be required to build the cert chain. Finally, the TrustedRoots object can be used to provide a way of making trusted root certificates available.

Note: Prior to v9.5.0.50, this method would fail if the certificate chain could not be completed to the root. Starting in v9.5.0.50, the incomplete certificate chain will be returned. The certificate chain's ReachesRoot property can be examined to see if the chain was completed to the root.

On Windows systems, the registry-based certificate stores are automatically consulted if needed to locate intermediate or root certificates in the chain.

The private key is specified by providing the name of the key container where it can be found. The 2nd argument indicates whether the key container is from the machine-wide keyset (1), or from the keyset specific to the logged-on user (0). Private keys can be imported into a key container by calling the KeyContainer's ImportPrivateKey method. Once a certificate has been linked, the private key is available for creating digital signatures or decrypting. Note: Certificates imported from a PFX or from a Certificate Authority will already be "linked" and it is not necessary to call this method.
