CkoCert

Current Version: 9.5.0.97

Digital certificate component / class

Object Creation

let obj = CkoCert()

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
CertVersion
CertVersion: Int (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
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: Bool (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
ExtendedKeyUsage
ExtendedKeyUsage: String (read-only)
Introduced in version 9.5.0.85

Returns a string containing a comma separated list of keywords with the extended key usages of the certificate. The list of possible extended key usages are:

  • serverAuth - TLS WWW server authentication
  • clientAuth - TLS WWW client authentication
  • codeSigning - Signing of downloadable executable code
  • emailProtection - Email protection
  • timeStamping - Binding the hash of an object to a time
  • OCSPSigning - Signing OCSP responses

top

top
LastErrorHtml
LastErrorHtml: String (read-only)

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
LastErrorText: String (read-only)

Provides information in plain-text 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
LastErrorXml
LastErrorXml: String (read-only)

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
LastMethodSuccess: Bool

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
OcspUrl
OcspUrl: String (read-only)

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.)

More Information and Examples
top
Revoked
Revoked: Bool (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
Rfc822Name: String (read-only)

The RFC822 name of the certificate. (The RFC822 name is one part of the Subject Alternative Name extension of a certificate, if it exists. It is often the only part of the SAN.)

If the certificate contains a list of RFC822 names then this property will return the comma separated list of names.

Starting in Chilkat v9.5.0.85, to get the complete Subject Alternative Name extension as XML, use the SubjectAlternativeName property.

top
TrustedRoot
TrustedRoot: Bool (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

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
ValidFromStr
ValidFromStr: String (read-only)

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

top
ValidToStr
ValidToStr: String (read-only)

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

top
VerboseLogging
VerboseLogging: Bool

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
FindIssuer
FindIssuer() -> CkoCert

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 nil on failure

More Information and Examples
top
GetCertChain
GetCertChain() -> CkoCertChain
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 nil on failure

Returns nil on failure

top
GetExtensionAsText
GetExtensionAsText(oid: String) -> 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 nil on failure

More Information and Examples
top
GetExtensionAsXml
GetExtensionAsXml(oid: String) -> 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

Note: In many cases, the data within the XML is returned base64 encoded. An application may need to take one further step to base64 decode the information contained within the XML.

LoadFromBd(certBytes: CkoBinData) -> Bool
Introduced in version 9.5.0.70

Loads an X.509 certificate from data contained in certBytes.

Note: The certBytes 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.

More Information and Examples
top
LoadFromBinary
LoadFromBinary(data: NSData) -> Bool

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.

top
LoadFromFile
LoadFromFile(path: String) -> Bool

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: String) -> Bool
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)
  • eToken Base Cryptographic Provider

Events

To implement an event callback, your application would define and implement a class that inherits from CkoBaseProgress. Your application can implement methods to override some or all of the default/empty method implementations of the CkoBaseProgress base class.

For example:

class MyCertProgress : CkoBaseProgress {

    override func ProgressInfo(name: String!, value: String!) {
        // application code goes here...
        print(name + ": " + value)
    }

    override func AbortCheck(abort: UnsafeMutablePointer) {
        // application code goes here...
        // To abort the operation, set this equal to true instead of false.
        abort.memory = false
    }

    override func PercentDone(pctDone: NSNumber!, abort: UnsafeMutablePointer) {
        // application code goes here...
        print(pctDone)
        // To abort the operation, set this equal to true instead of false.
        abort.memory = false
    }

    // For asynchronous method calls.
    override func TaskCompleted(task: CkoTask!) {
        // application code goes here...
    }
}

func someAppFunction() {

    // Demonstrate how to set the event callback object...
    let cert = CkoCert()
    let myCertProgress = MyCertProgress()
    
    cert.setEventCallbackObject(myCertProgress)

    // ...
    // ...
    // ...
}

AbortCheck
AbortCheck(abort: Bool)

Provides the opportunity for a method call to be aborted. The AbortCheck event is fired periodically based on the value of the HeartbeatMs property. If HeartbeatMs is 0, then no AbortCheck events will fire. As an example, to fire 5 AbortCheck events per second, set the HeartbeatMs property equal to 200.

PercentDone
PercentDone(pctDone: Int, abort: Bool)

Provides the percentage completed for any method that involves network communications or time-consuming processing (assuming it is a method where a percentage completion can be measured). This event is only fired when it is possible to know a percentage completion, and when it makes sense to express the operation as a percentage completed. The pctDone argument will have a value from 1 to 100. For operations (Chilkat method calls) that complete very quickly, the number of PercentDone callbacks will vary, but the final callback should have a value of 100. For long running operations, no more than one callback per percentage point will occur (for example: 1, 2, 3, ... 98, 99, 100).

The PercentDone callback counts as an AbortCheck event. For method calls that complete quickly such that PercentDone events fire, it may be that AbortCheck events don't fire because the opportunity to abort is already provided in the PercentDone callback. For time consuming operations, where the amount of time between PercentDone callbacks are long, AbortCheck callbacks may be used to allow for the operation to be aborted in a more responsive manner.

The abort output argument provides a means for aborting the operation. Setting it to true will cause the method to abort and return a failed status (or whatever return value indicates failure).

ProgressInfo
ProgressInfo(name: String, value: String)

A general name/value event that provides information about what is happening during a method call. To find out what information is available, write code to handle this event and log the name/value pairs. Most are self-explanatory.

TaskCompleted
TaskCompleted(task: CkoTask)

Called in the background thread when an asynchronous task completes.
