PrivateKey ActiveX Reference Documentation

PrivateKey

Current Version: 10.0.0

Contains an RSA, DSA, or ECC private key. Provides methods for importing and exporting to/from PEM, DER, PKCS8, PKCS1, PVK, and XML formats. Private keys can be imported/exported to both memory and files.

Object Creation

Note:
For versions of Chilkat < 10.0.0, use "Chilkat_9_5_0.PrivateKey" instead of "Chilkat.PrivateKey"
For a specific major version, use "Chilkat.PrivateKey.<major_version>", such as "Chilkat.PrivateKey.10" for Chilkat v10.*.*
See Chilkat ActiveX Object Creation

(ASP)
set obj = Server.CreateObject("Chilkat.PrivateKey")

(AutoIt)

Properties

BitLength
BitLength As Long (read-only)
Introduced in version 9.5.0.49

The bit length (strength) of the private key.

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
KeyType
KeyType As String (read-only)
Introduced in version 9.5.0.52

The type of private key. Can be "empty", "rsa", "dsa", "ecc" (i.e. ECDSA), or "ed25519".

top
LastBinaryResult
LastBinaryResult As Variant (read-only)

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
LastErrorHtml As 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 As 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 As 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 As Long

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
LastStringResult As String (read-only)

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
LastStringResultLen As Long (read-only)

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

top
Pkcs8EncryptAlg
Pkcs8EncryptAlg As String
Introduced in version 9.5.0.49

The encryption algorithm to be used when exporting the key to encrypted PKCS8. The default value is "3des". Possible choices also include "aes128", "aes192", and "aes256". All of the encryption algorithm choices use CBC mode.

top
UncommonOptions
UncommonOptions As String
Introduced in version 9.5.0.96

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 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
Version As String (read-only)

Version of the component/library, such as "9.5.0.94"

top

Events

AbortCheck
AbortCheck(abort As Long)

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.

VB6 Event callback implementation:

Important: Event callbacks from asynchronous method calls are generally not possible from the ActiveX. See VB6 Async Callbacks

Dim WithEvents myPrivatekey As PrivateKey

Private Sub myPrivatekey_AbortCheck(abort As Long)

	'Insert application code here.

End Sub
top
PercentDone
PercentDone(ByVal pctDone As Long, abort As Long)

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 1 will cause the method to abort and return a failed status (or whatever return value indicates failure).

Private Sub myPrivatekey_PercentDone(ByVal pctDone As Long, abort As Long)

	'Insert application code here.

End Sub
top
ProgressInfo
ProgressInfo(ByVal name As String, ByVal value As 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.
