Windows Credentials Manager - AutoSplit Larger Secrets

See more Secrets Examples

Secrets stored in the Windows Credentials Manager can be a maximum of 2560 bytes in size. If the content of the secret is too large for the Windows Credential Manager, Chilkat will automatically split the secret into parts and store a shorter JSON manifest.

Note: This example requires Chilkat v10.1.0 or later.

Go

    success := false

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    secrets := chilkat.NewSecrets()

    // The default value of AutoSplit is true.
    // Note: AutoSplit only applies when the secret location is "local_manager"
    // and the app is running on the Windows OS.  All other secret locations, such as Apple Keychain,
    // AWS Secrets Manager, Azure Key Vault, etc. don't have limitations that are so small.
    secrets.SetAutoSplit(true)

    // On Windows, this is the Windows Credentials Manager
    // On MacOS/iOS, it is the Apple Keychain
    // (This example is explaining how a secret too large for the Windows Credential Manager
    // is automatically compressed and split into parts if needed.)
    secrets.SetLocation("local_manager")

    // Specify the name of the secret.
    // service and username are required.
    // appName and domain are optional.
    // Note: The values are arbitrary and can be anything you want.
    json := chilkat.NewJsonObject()
    json.UpdateString("appName","AA_MyApp")
    json.UpdateString("service","OAuth2")
    json.UpdateString("domain","onedrive")
    json.UpdateString("username","matt")

    // Get the secret to be stored.
    jsonSecret := chilkat.NewJsonObject()
    success = jsonSecret.LoadFile("qa_data/tokens/oneDrive.json")
    if success == false {
        fmt.Println(jsonSecret.LastErrorText())
        secrets.DisposeSecrets()
        json.DisposeJsonObject()
        jsonSecret.DisposeJsonObject()
        return
    }

    // Note: The oneDrive.json file we used for testing is 4824 bytes in size,
    // which exceeds the maximum size (2560 bytes) allowed by the Windows Credentials Manager.

    // When the size is too large, Chilkat will first compress the content of the secret.
    // If the compressed size is small enough, then it is stored compressed without splitting.
    // Otherwise the compressed data is split

    // Your application does not need to know how the secret is stored in the Windows Credentials Manager.
    // When fetching the secret, Chilkat automatically decompresses and re-composes from parts.

    // Create or update the secret.
    success = secrets.UpdateSecretJson(json,jsonSecret)
    if success == false {
        fmt.Println(secrets.LastErrorText())
        secrets.DisposeSecrets()
        json.DisposeJsonObject()
        jsonSecret.DisposeJsonObject()
        return
    }

    // This is the auto-split secret viewed in the Windows Credentials Manager:
    // 

    // Note: If you delete the auto-split secret by calling Chilkat's DeleteSecret method,
    // the parts are automatically deleted.
    // Also, if you update the secret, the old parts are automatically deleted and new parts are created.

    fmt.Println("Success")
