## 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**

```java
CkAuthAzureStorage obj = new CkAuthAzureStorage();
```

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 Java.

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` | `void get_DebugLogFilePath(CkString str); String debugLogFilePath(); void put_DebugLogFilePath(String newVal);` | 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` | `void get_LastErrorHtml(CkString str); String lastErrorHtml();` | read-only | Provides HTML-formatted information about the last called method or property. |
| `LastErrorText` | `void get_LastErrorText(CkString str); String lastErrorText();` | read-only | Provides plain text information about the last called method or property. |
| `LastErrorXml` | `void get_LastErrorXml(CkString str); String lastErrorXml();` | read-only | Provides XML-formatted information about the last called method or property. |
| `LastMethodSuccess` | `boolean get_LastMethodSuccess(); void put_LastMethodSuccess(boolean newVal);` | read/write | Indicates the success or failure of the most recent method call: `true` means success, `false` means failure. |
| `VerboseLogging` | `boolean get_VerboseLogging(); void put_VerboseLogging(boolean newVal);` | read/write | If set to `true`, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. |
| `Version` | `void get_Version(CkString str); String version();` | read-only | Version of the component/library, such as "10.1.0" |

## Member index

| Member | Kind | Signature |

| `Scheme` | property, read/write | `void get_Scheme(CkString str); String scheme(); void put_Scheme(String newVal);` |
| `Service` | property, read/write | `void get_Service(CkString str); String service(); void put_Service(String newVal);` |
| `XMsVersion` | property, read/write | `void get_XMsVersion(CkString str); String xMsVersion(); void put_XMsVersion(String newVal);` |

## Properties

### AuthAzureStorage.AccessKey

`Chilkat 11.7.0 · ckjava · AuthAzureStorage · AccessKey · property · read/write · since 9.5.0.58`

```java
void get_AccessKey(CkString str);

String accessKey();

void put_AccessKey(String newVal);
```

A valid base64 access key for the Azure storage account.

### AuthAzureStorage.Account

```java
void get_Account(CkString str);

String account();

void put_Account(String newVal);
```

The Azure storage account name. (A storage account can contain zero or more containers. A container contains properties, metadata, and zero or more blobs. A blob is any single entity comprised of binary data, properties, and metadata. )

### AuthAzureStorage.Scheme

`Chilkat 11.7.0 · ckjava · AuthAzureStorage · Scheme · property · read/write · since 9.5.0.58`

```java
void get_Scheme(CkString str);

String scheme();

void put_Scheme(String newVal);
```

Can be `SharedKey` or `SharedKeyLite`. The default value is `SharedKey`.

### AuthAzureStorage.Service

```java
void get_Service(CkString str);

String service();

void put_Service(String newVal);
```

Can be `Blob`, `Queue`, `File`, or `Table`. The default is `Blob`.

**Note:** Authentication for the `Table` service did not work in versions prior to v9.5.0.83.

### AuthAzureStorage.XMsVersion

`Chilkat 11.7.0 · ckjava · AuthAzureStorage · XMsVersion · property · read/write · since 9.5.0.58`

```java
void get_XMsVersion(CkString str);

String xMsVersion();

void put_XMsVersion(String newVal);
```

If set, automatically adds the `x-ms-version` HTTP request header to Azure Storage requests. The default value is `2014-02-14`.
