Secrets

The AutoSplit property is specific to "local_manager" secrets on Windows. The Windows Credentials Manager supports a maximum of 2560 bytes per secret. If a secret exceeds this size, it will be automatically compressed and split when created or updated, and automatically recomposed when retrieved.

A secret can be split into a maximum of 10 parts.

The default value is 1.

If set to 1, then the contents of the secret will be stored compressed. The default value of this property is 0.

If set to a file path, this property logs the LastErrorText of each Chilkat method or property call to the specified file. This logging helps identify the context and history of Chilkat calls leading up to any crash or hang, aiding in debugging.

Enabling the VerboseLogging property provides more detailed information. This property is mainly used for debugging rare instances where a Chilkat method call causes a hang or crash, which should generally not happen.

Possible causes of hangs include:

• A timeout property set to 0, indicating an infinite timeout.
• A hang occurring within an event callback in the application code.
• An internal bug in the Chilkat code causing the hang.

This property is mainly used in SQL Server stored procedures to retrieve binary data from the last method call that returned binary data. It is only accessible if Chilkat.Global.KeepBinaryResult is set to 1. This feature allows for the retrieval of large varbinary results in an SQL Server environment, which has restrictions on returning large data via method calls, though temp tables can handle binary properties.

Provides HTML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.

Provides plain text information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.

Provides XML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.

Indicates the success or failure of the most recent method call: 1 means success, 0 means failure. This property remains unchanged by property setters or getters. This method is present to address challenges in checking for null or Nothing returns in certain programming languages.

In SQL Server stored procedures, this property holds the string return value of the most recent method call that returns a string. It is accessible only when Chilkat.Global.KeepStringResult is set to TRUE. SQL Server has limitations on string lengths returned from methods and properties, but temp tables can be used to access large strings.

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

The location of the secrets. Possible values are:

• "local_manager" - On Windows this is the Credentials Manager. On MacOS and iOS it is the Keychain. This is not yet an option on Linux or Android.
• "aws_secrets_manager" - AWS Secrets Manager
• "azure_key_vault" - Azure Key Vault
• "ibm_cloud" - IBM Cloud Secrets Manager
• "oracle_cloud" - Oracle Cloud Secrets
• "doppler" - Doppler Secrets
• "memory" - In-Memory Secrets

The default location is the "local_manager". On Linux and Android, "local_manager" will behave the same as "memory".

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

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.

Version of the component/library, such as "10.1.0"

Deletes a secret. Cloud secrets managers will typically disable the secret and schedule the secret for deletion after some number of days.

Returns 1 for success, 0 for failure.

Creates an asynchronous task to call the DeleteSecret method with the arguments provided.

Note: Async method event callbacks happen in the background thread. Accessing and updating UI elements existing in the main thread may require special considerations.

Returns Nothing on failure

Fetches a binary secret and returns the content in bd.

Returns 1 for success, 0 for failure.

Creates an asynchronous task to call the GetSecretBd method with the arguments provided.

Note: Async method event callbacks happen in the background thread. Accessing and updating UI elements existing in the main thread may require special considerations.

Returns Nothing on failure

Fetches a JSON secret and returns the content in jsonOut.

Returns 1 for success, 0 for failure.

Creates an asynchronous task to call the GetSecretJson method with the arguments provided.

Lists secrets matching the wildcarded or exact values passed in json. The results of the query are returned in jsonOut.

Returns 1 for success, 0 for failure.

Returns Nothing on failure

Accessing a cloud-based secrets manager requires authentication credentials, which cannot be stored in the manager itself. Instead, they must be securely stored locally.

One solution is to store the authentication credentials as a secret in the Windows Credentials Manager or Apple Keychain. These credentials serve as the "bootstrap secret" for authenticating with the cloud-based secrets manager.

jsonId contains the name of the bootstrap secret. secretContent contains the bootstrap's secret content.

Returns 1 for success, 0 for failure.

Creates a binary secret if it does not yet exist, or updates an existing secret. The name of the secret is specified in jsonId, and the binary content of the secret in secret.

Returns 1 for success, 0 for failure.

Creates an asynchronous task to call the UpdateSecretBd method with the arguments provided.

Note: Async method event callbacks happen in the background thread. Accessing and updating UI elements existing in the main thread may require special considerations.

Returns Nothing on failure

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 mySecrets As ChilkatSecrets

Private Sub mySecrets_AbortCheck(abort As Long)

	'Insert application code here.

End Sub

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).

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.
