## Purpose

**Authenticate Azure Storage REST requests with account-key Shared Key signing.**

`Chilkat.AuthAzureStorage` is a credential object for Azure Storage Services authentication. It stores the storage account name, Base64 account access key, Azure Storage service type, authentication scheme, and `x-ms-version` API version used when signing REST requests for Blob, Queue, File, or Table storage.

**Azure Storage credentials**

Hold the storage account name and Base64 account access key used to sign Azure Storage REST requests.

**Shared Key signing**

Configure Azure Storage authentication using `SharedKey` or `SharedKeyLite`, depending on the service and request style.

**Service targeting**

Specify the Azure Storage service being accessed, such as `Blob`, `Queue`, `File`, or `Table`.

**API version header**

Set the `x-ms-version` value required by the Azure Storage REST API version being used.

**REST integration**

Use the configured object with `Chilkat.Rest` so requests are signed automatically before being sent.

**Low-level control**

Pair this authentication object with manually constructed REST requests when application code needs direct control over Azure Storage operations.

**Common pattern:** Create an `AuthAzureStorage` object, set the storage `Account`, Base64 `AccessKey`, `Service`, `Scheme`, and `XMsVersion`, then attach it to a `Chilkat.Rest` request workflow. Use `AuthAzureStorage` for Shared Key authorization headers; use `Chilkat.AuthAzureSAS` when the request should be authorized with a SAS query token instead.

For an extended overview, see [AuthAzureStorage Class Overview](https://www.chilkatsoft.com/authazurestorage_class_overview.asp).

## Object creation, unlocking and error handling

**Object Creation**

```python
obj = chilkat2.AuthAzureStorage()
```

Call `Global.UnlockBundle` once at the start of the program, before using this or any other Chilkat class. Any string unlocks a fully functional 30-day trial; a purchased unlock code is used in production. See `guide.md` for the exact code in Python.

Minimal complete program:

```python
import chilkat2

# Required once per process. Any string unlocks a 30-day trial; use your purchased code in production.
glob = chilkat2.Global()
if not glob.UnlockBundle("Anything for 30-day trial"):
    print(glob.LastErrorText)
    raise SystemExit(1)

authAzureStorage = chilkat2.AuthAzureStorage()
```

How failure is reported depends on the method's return type and is stated in the note under each method below. In every case the diagnostic text is in the `LastErrorText` property of the object whose method was called.

## Members common to every Chilkat class

Documented once per language in `common-members.md`; listed here so this page is self-contained.

| Property | Signature | Access | Meaning |
|---|---|---|---|
| `DebugLogFilePath` | `string DebugLogFilePath` | read/write | If set to a file path, this property logs the LastErrorText of each Chilkat method or property call to the specified file. |
| `LastErrorHtml` | `string LastErrorHtml (read-only)` | read-only | Provides HTML-formatted information about the last called method or property. |
| `LastErrorText` | `string LastErrorText (read-only)` | read-only | Provides plain text information about the last called method or property. |
| `LastErrorXml` | `string LastErrorXml (read-only)` | read-only | Provides XML-formatted information about the last called method or property. |
| `LastMethodSuccess` | `bool LastMethodSuccess` | read/write | Indicates the success or failure of the most recent method call: `True` means success, `False` means failure. |
| `VerboseLogging` | `bool VerboseLogging` | read/write | If set to `True`, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. |
| `Version` | `string Version (read-only)` | read-only | Version of the component/library, such as "10.1.0" |

## Member index

| Member | Kind | Signature |
|---|---|---|
| `AccessKey` | property, read/write | `string AccessKey` |
