Digital certificate component / class

Object Creation

var obj = new chilkat.Cert();

Properties

AuthorityKeyId
AuthorityKeyId
· 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
· boolean

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
· integer, 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
· 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
· 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
· boolean, read-only

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

top
LastMethodSuccess
LastMethodSuccess
· boolean

Indicate whether the last method call succeeded or failed. A value of true indicates success, a value of false 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 = 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
MachineKeyset
MachineKeyset
· boolean, 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 indicates whether the key container is in the machine's keyset or in the keyset specific to the logged on user's account. If true, the key container is within the machine keyset. If false, 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.

Revoked
· boolean, read-only

true 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 false, 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

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
SmartCardNoDialog
SmartCardNoDialog
· boolean
Introduced in version 9.5.0.77

If set to true, then no dialog will automatically popup if the SmartCardPin is incorrect. Instead, the method requiring the private key on the smart card will fail. The default value of this property is false, which means that if the SmartCardPin property is incorrect, a dialog with prompt will be displayed.

top

top
TrustedRoot
TrustedRoot
· boolean, 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
· string
Introduced in version 9.5.0.87

top
VerboseLogging
VerboseLogging
· boolean

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.

Methods

CheckRevoked
var retInt = CheckRevoked();
· Returns a Number.

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.

GetCertChain
var ret_certChain = GetCertChain();
· Returns a 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

· Returns Boolean (true for success, false for failure).
· data Buffer

Loads an X.509 certificate from ASN.1 DER encoded bytes.

Note: The data may contain the certificate in any format. It can be binary DER (ASN.1), PEM, Base64, etc. Chilkat will automatically detect the format.

Returns true for success, false for failure.

LoadFromFile
var status = LoadFromFile(path);
· Returns Boolean (true for success, false for failure).
· path String

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.

LoadFromSmartcard
var status = LoadFromSmartcard(csp);
· Returns Boolean (true for success, false for failure).
· csp String
Introduced in version 9.5.0.77

Important: It's important to set the SmartCardPin property before calling this method.

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
  • Bit4id Universal Middleware Provider
  • YubiHSM Key Storage Provider (starting in v9.5.0.83)
