Digital certificate component / class

Create/Dispose

var
myObject: HCkCert;

begin
myObject := CkCert_Create();

// ...

CkCert_Dispose(myObject);
end;
function CkCert_Create: HCkCert; stdcall;

Creates an instance of the HCkCert object and returns a handle (i.e. a Pointer). The handle is passed in the 1st argument for the functions listed on this page.

procedure CkCert_Dispose(handle: HCkCert); stdcall;

Objects created by calling CkCert_Create must be freed by calling this method. A memory leak occurs if a handle is not disposed by calling this function.

Properties

AuthorityKeyId
procedure CkCert_getAuthorityKeyId(objHandle: HCkCert; outPropVal: HCkString); stdcall;
function CkCert__authorityKeyId(objHandle: HCkCert): PWideChar; stdcall;
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
function CkCert_getAvoidWindowsPkAccess(objHandle: HCkCert): wordbool; stdcall;
procedure CkCert_putAvoidWindowsPkAccess(objHandle: HCkCert; newPropVal: wordbool); stdcall;

Applies only when running on a Microsoft Windows operating system. If True, 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 False.

top
CertVersion
function CkCert_getCertVersion(objHandle: HCkCert): Integer; stdcall;

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
procedure CkCert_getCspName(objHandle: HCkCert; outPropVal: HCkString); stdcall;
function CkCert__cspName(objHandle: HCkCert): PWideChar; stdcall;

(Relevant only when running on a Microsoft Windows operating system.) If the HasKeyContainer property is True, 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
procedure CkCert_getDebugLogFilePath(objHandle: HCkCert; outPropVal: HCkString); stdcall;
procedure CkCert_putDebugLogFilePath(objHandle: HCkCert; newPropVal: PWideChar); stdcall;
function CkCert__debugLogFilePath(objHandle: HCkCert): PWideChar; stdcall;

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
Expired
function CkCert_getExpired(objHandle: HCkCert): wordbool; stdcall;

Has a value of True if the certificate or any certificate in the chain of authority has expired. (This information is not available when running on Windows 95/98 computers.)

top
HasKeyContainer
function CkCert_getHasKeyContainer(objHandle: HCkCert): wordbool; stdcall;

(Relevant only when running on a Microsoft Windows operating system.) Indicates whether this certificate is linked to a key container. If True then the certificate is linked to a key container (usually containing a private key). If False, then it is not.

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.

  • 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.

top
TrustedRoot
function CkCert_getTrustedRoot(objHandle: HCkCert): wordbool; stdcall;

Returns True if the certificate has a trusted root authority, otherwise returns False.

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 False 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 True, 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
GetCertChain
function CkCert_GetCertChain(objHandle: HCkCert): HCkCertChain; stdcall;
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). If this certificate object was loaded from a PFX, then the certiicates contained in the PFX are automatically available for building the certificate chain. 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.

Introduced in version 9.5.0.75

Returns an encoded hash of a particular part of the certificate. The part may be one of the following:

  • IssuerDN
  • IssuerPublicKey
  • SubjectDN
  • SubjectPublicKey

The hashAlg is the name of the hash algorithm, such as "sha1", "sha256", "sha384", "sha512", "md5", etc. The encoding is the format to return, such as "hex", "base64", etc.

Returns True for success, False for failure.

HasPrivateKey
function CkCert_HasPrivateKey(objHandle: HCkCert): wordbool; stdcall;

Returns true if the private key is installed on the local system for the certificate.

top
LinkPrivateKey
function CkCert_LinkPrivateKey(objHandle: HCkCert;
    keyContainerName: PWideChar;
    bMachineKeyset: wordbool;
    bForSigning: wordbool): wordbool; stdcall;

(Relevant only when running on a Microsoft Windows operating system.) Associates a private key with a certificate. 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 (True), or from the keyset specific to the logged-on user (False). 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.

Returns True for success, False for failure.

    pByteData: pbyte;
    szByteData: LongWord): wordbool; stdcall;

The same as LoadFromBinary, but instead of using a CkByteData object, the pointer to the byte data and length (in number of bytes) are specified directly in the method arguments.

top
LoadFromFile
function CkCert_LoadFromFile(objHandle: HCkCert;
    path: PWideChar): wordbool; stdcall;

Loads a certificate from a .cer, .crt, .p7b, or .pem file. This method accepts certificates from files in any of the following formats:
1. DER encoded binary X.509 (.CER)
2. Base-64 encoded X.509 (.CER)
3. Cryptographic Message Syntax Standard - PKCS #7 Certificates (.P7B)
4. PEM format
This method decodes the certificate based on the contents if finds within the file, and not based on the file extension. If your certificate is in a file having a different extension, try loading it using this method before assuming it won't work. This method does not load .p12 or .pfx (PKCS #12) files.

Returns True for success, False for failure.
