Current Version: 9.5.0.90

Digital certificate component / class

Object Creation

Dim oCert As Chilkat.Cert
Set oCert = Chilkat.NewCert

Properties

AuthorityKeyId
AuthorityKeyId As String (read only)
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
AvoidWindowsPkAccess As Long

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
CertVersion As Long (read only)

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
CspName As String (read only)

(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
DebugLogFilePath As String

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
Expired As Long (read only)

top
TrustedRoot
TrustedRoot As Long (read only)

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
UncommonOptions
UncommonOptions As String
Introduced in version 9.5.0.87

This is a catch-all property to be used for uncommon needs. This property defaults to the empty string, and should typically remain empty.

top
VerboseLogging
VerboseLogging As Long

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.

top

Version of the component/library, such as "9.5.0.63"

top

Methods

CheckRevoked
CheckRevoked() As Long

Returns 1 if the certificate has been revoked, 0 if not revoked, and -1 if unable to check the revocation status.

Note: This method is only implemented on Windows systems. It uses the underlying Microsoft CertVerifyRevocation Platform SDK function to check the revocation status of a certificate. (Search "CertVerifyRevocation" to get information about it.)

Non-Windows (and Windows) applications can send an OCSP request as shown in the example below.

More Information and Examples
top
CheckSmartCardPin
CheckSmartCardPin() As Long
Introduced in version 9.5.0.77

Verifies that the SmartCardPin property setting is correct. Returns 1 if correct, 0 if incorrect, and -1 if unable to check because the underlying CSP does not support the functionality.

Finds and returns the issuer certificate. If the certificate is a root or self-issued, then the certificate returned is a copy of the caller certificate. (The IsRoot property can be check to see if the certificate is a root (or self-issued) certificate.)

Returns Nothing on failure

More Information and Examples
top
GetCertChain
GetCertChain() As CertChain
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.

On Windows systems, the registry-based certificate stores are automatically consulted if needed to locate intermediate or root certificates in the chain. Chilkat searches certificate stores in the following order. See System Store Locations for more information.

  1. Current-User "CA" Certificate Store
  2. Local-Machine "CA" Certificate Store
  3. Current-User "Root" Certificate Store
  4. Local-Machine "Root" Certificate Store
  5. Current-User "MY" Certificate Store
  6. Local-Machine "MY" Certificate Store
  7. Current-User "ADDRESSBOOK" Certificate Store (if it exists)
  8. Local-Machine "ADDRESSBOOK" Certificate Store (if it exists)

Returns Nothing on failure

top
GetExtensionAsText
GetExtensionAsText(oid As String) As String
Introduced in version 9.5.0.89

Returns the certificate extension data as a string. This method should only be called for those extensions with text values NOT stored as binary ASN.1. In most cases, applications should call GetExtensionAsXml because most extensions contain ASN.1 values that need to be decoded..

Returns Nothing on failure

More Information and Examples
top
GetExtensionAsXml
GetExtensionAsXml(oid As String) As String
Introduced in version 9.5.0.49

Returns the certificate extension data in XML format (converted from ASN.1). The oid is an OID, such as the ones listed here: http://www.alvestrand.no/objectid/2.5.29.html

LoadFromFile
LoadFromFile(path As String) As Long

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.

top
LoadFromSmartcard
LoadFromSmartcard(csp As String) As Long
Introduced in version 9.5.0.77

Starting in Chilkat v9.5.0.87, the csp can be a string that specifies the certificate to be loaded by either Subject Common Name (CN) or hex serial number. For example, instead of passing a CSP name, your application would pass a string such as "CN=The cert subject common name" or "serial=01020304". See the linked examples below. If a certificate is specified by CN or Serial, then each connected smartcard and USB token is searched for the matching certificate. If the certificate is found, it is loaded and this method returns True.

Otherwise, this method loads the X.509 certificate from the smartcard currently in the reader, or from a USB token.

If the smartcard contains multiple certificates, this method arbitrarily picks one.

If the csp does not begin with "CN=" or "serial=", then the csp can be set to the name of the CSP (Cryptographic Service Provider) that should be used. If csp is an empty string, then the 1st CSP found matching one of the following names will be used:

  • Microsoft Smart Card Key Storage Provider
  • Microsoft Base Smart Card Crypto Provider

SetPrivateKeyPem
SetPrivateKeyPem(privKeyPem As String) As Long

Same as SetPrivateKey, but the key is provided in unencrypted PEM format. (Note: The privKeyPem is not a file path, it is the actual PEM text.)

Returns True for success, False for failure.

UseCertVault
UseCertVault(vault As XmlCertVault) As Long
Introduced in version 9.5.0.40

Adds an XML certificate vault to the object's internal list of sources to be searched for certificates for help in building certificate chains and verifying the certificate signature to the trusted root.

Returns True for success, False for failure.

X509PKIPathv1
X509PKIPathv1() As String
Introduced in version 9.5.0.77

Returns the base64 representation of an X509PKIPathv1 containing just the calling certificate. This is typically used in an X.509 Binary Security Token. It is a PKIPath that contains an ordered list of X.509 public certificates packaged in a PKIPath. The X509PKIPathv1 token type may be used to represent a certificate path. (This is sometimes used in XAdES signatures.)

Returns Nothing on failure
