This article describes how to work with Azure storage containers and securely write data files using SAS URIs with Python.
Storage containers are a way to organize a collection of blobs in public cloud, basically like folders. You can manage user access to containers using role-based access control (RBAC) just like other cloud resources. Another more anonymous way to manage access is with Shared Access Signature (SAS) keys.
Suppose you are working with a producer and want to give them a way to write files to your cloud storage container without being able to read any files. Similarly you want to let a consumer read data from the container without being able to make any changes or read from other containers. SAS keys provide a simple way to manage access to a storage container without the complexity of managing role-based access. Anyone who has a valid key can access the resource.
In this example you could give the producer a write-only key, and the consumer a key with read and list permissions, and set expiry dates for both keys for the duration of the contract. For convenience a SAS key can be provided in the form of a URI, also known as a SAS URI.
A limitation of using SAS keys is that it is only as secure as your key management. If your consumer were to share their read-key with a third party or store it insecurely, then anyone with access to the key could read the data. Therefore it is most useful for limited-duration data exchange where there is a trusted key-management process.

Creating a storage container and SAS URIs using CLI
You can create storage containers and SAS URIs using the Azure portal or by command line.
The script below shows a Bash script which can be run from the Azure Cloud Shell. It uses Azure CLI to create a storage account, a container, and two SAS URIs, one with read-list permissions, and one with write-only permissions. It’s also on github here.
Writing data to a write-only SAS URI using Python
Assuming you’ve created SAS URIs with the required permissions and date range, here’s a Python example of using a write-only SAS URI to write data to an Azure container. It takes some text as a command line argument, and writes it to a blob in the container. This example can be found on github here.
-->Beginning with version 2015-04-05, Azure Storage supports creating a new type of shared access signature (SAS) at the level of the storage account. Creating an account SAS enables you to:
Delegate access to service-level operations that are not currently available with a service-specific SAS, such as the
Get/Set Service PropertiesandGet Service Statsoperations.Delegate access to more than one service in a storage account at a time. For example, you can delegate access to resources in both the Blob and File services with an account SAS.
Delegate access to write and delete operations for containers, queues, tables, and file shares, which are not available with an object-specific SAS.
Specify an IP address or range of IP addresses from which to accept requests.
Specify the HTTP protocol from which to accept requests (either HTTPS or HTTP/HTTPS).
Stored access policies are currently not supported for account SAS.
Caution
Shared access signature are keys that grant permissions to storage resources, and should be protected in the same manner as an account key. It's important to protect a SAS from malicious or unintended use. Use discretion in distributing a SAS, and have a plan in place for revoking a compromised SAS. Operations that use shared access signatures should be performed only over an HTTPS connection, and shared access signature URIs should only be distributed on a secure connection such as HTTPS.
Authorization of an account SAS
An account SAS is secured using the storage account key. To create an account SAS, a client application must possess the account key.
To use Azure AD credentials to secure a SAS for a container or blob, create a user delegation SAS. For more information, see Create a user delegation SAS.
Constructing the Account SAS URI
The account SAS URI consists of the URI to the resource for which the SAS will delegate access, followed by the SAS token. The SAS token is the query string that includes all of the information required to authorize a request to the resource, as well as to specify the service, resource, and permissions available for access, and the time interval over which the signature is valid.
Specifying Account SAS Parameters
The following table describes the required and optional parameters for the SAS token.
| SAS Query Parameter | Description |
|---|---|
api-version | Optional. Specifies the storage service version to use to execute the request made using the account SAS URI. |
SignedVersion (sv) | Required. Specifies the signed storage service version to use to authorize requests made with this account SAS. Must be set to version 2015-04-05 or later. |
SignedServices (ss) | Required. Specifies the signed services accessible with the account SAS. Possible values include: - Blob ( b)- Queue ( q)- Table ( t)- File ( f)You can combine values to provide access to more than one service. For example, ss=bf specifies access to the Blob and File endpoints. |
SignedResourceTypes (srt) | Required. Specifies the signed resource types that are accessible with the account SAS. - Service ( s): Access to service-level APIs (e.g., Get/Set Service Properties, Get Service Stats, List Containers/Queues/Tables/Shares)- Container ( c): Access to container-level APIs (e.g., Create/Delete Container, Create/Delete Queue, Create/Delete Table, Create/Delete Share, List Blobs/Files and Directories)- Object ( o): Access to object-level APIs for blobs, queue messages, table entities, and files(e.g. Put Blob, Query Entity, Get Messages, Create File, etc.)You can combine values to provide access to more than one resource type. For example, srt=sc specifies access to service and container resources. |
SignedPermission (sp) | Required. Specifies the signed permissions for the account SAS. Permissions are only valid if they match the specified signed resource type; otherwise they are ignored. - Read ( r): Valid for all signed resources types (Service, Container, and Object). Permits read permissions to the specified resource type.- Write ( w): Valid for all signed resources types (Service, Container, and Object). Permits write permissions to the specified resource type.- Delete ( d): Valid for Container and Object resource types, except for queue messages.- List ( l): Valid for Service and Container resource types only.- Add ( a): Valid for the following Object resource types only: queue messages, table entities, and append blobs.- Create ( c): Valid for the following Object resource types only: blobs and files. Users can create new blobs or files, but may not overwrite existing blobs or files.- Update ( u): Valid for the following Object resource types only: queue messages and table entities.- Process ( p): Valid for the following Object resource type only: queue messages. |
SignedStart (st) | Optional. The time at which the SAS becomes valid, in an ISO 8601 format. If omitted, start time for this call is assumed to be the time when the storage service receives the request. |
SignedExpiry (se) | Required. The time at which the shared access signature becomes invalid, in an ISO 8601 format. |
SignedIP (sip) | Optional. Specifies an IP address or a range of IP addresses from which to accept requests. When specifying a range, note that the range is inclusive. For example, sip=168.1.5.65 or sip=168.1.5.60-168.1.5.70. |
SignedProtocol (spr) | Optional. Specifies the protocol permitted for a request made with the account SAS. Possible values are both HTTPS and HTTP (https,http) or HTTPS only (https). The default value is https,http.Note that HTTP only is not a permitted value. |
Signature (sig) | Required. The signature part of the URI is used to authorize the request made with the shared access signature. The string-to-sign is a unique string constructed from the fields that must be verified in order to authorize the request. The signature is an HMAC computed over the string-to-sign and key using the SHA256 algorithm, and then encoded using Base64 encoding. |
Specifying the signature validity interval
The SignedStart and SignedExpiry fields must be expressed as UTC times and must adhere to a valid ISO 8601 format. Supported ISO 8601 formats include the following:
YYYY-MM-DD
YYYY-MM-DDThh:mmTZD
YYYY-MM-DDThh:mm:ssTZD
For the date portion of these formats, YYYY is a four-digit year representation, MM is a two-digit month representation, and DD is a two-digit day representation. For the time portion, hh is the hour representation in 24-hour notation, mm is the two-digit minute representation, and ss is the two-digit second representation. A time designator T separates the date and time portions of the string, while a time zone designator TZD specifies the UTC time zone.
Constructing the signature string
To construct the signature string for an account SAS, first construct the string-to-sign from the fields comprising the request, then encode the string as UTF-8 and compute the signature using the HMAC-SHA256 algorithm. Note that fields included in the string-to-sign must be URL-decoded.
To construct the string-to-sign for an account SAS, use the following format:

Account SAS URI example
Azure Storage Account Sas Key
The following example shows an account SAS URI that provides read and write permissions to a blob. The table breaks down each part of the URI:
Azure Generate Storage Account Key Login
| Name | SAS portion | Description |
|---|---|---|
| Resource URI | https://myaccount.blob.core.windows.net/?restype=service&comp=properties | The service endpoint, with parameters for getting service properties (when called with GET) or setting service properties (when called with SET). Based on the value of the signed services field (ss), this SAS can be used with either Blob storage or Azure Files. |
| Storage services version | sv=2019-02-02 | For storage services version 2012-02-12 and later, this parameter indicates the version to use. |
| Services | ss=bf | The SAS applies to the Blob and File services |
| Resource types | srt=s | The SAS applies to service-level operations. |
| Start time | st=2019-08-01T22%3A18%3A26Z | Specified in UTC time. If you want the SAS to be valid immediately, omit the start time. |
| Expiry time | se=2019-08-10T02%3A23%3A26Z | Specified in UTC time. |
| Permissions | sp=rw | The permissions grant access to read and write operations. |
| IP range | sip=168.1.5.60-168.1.5.70 | The range of IP addresses from which a request will be accepted. |
| Protocol | spr=https | Only requests using HTTPS are permitted. |
| Signature | sig=F%6GRVAZ5Cdj2Pw4tgU7IlSTkWgn7bUkkAg8P6HESXwmf%4B | Used to authorize access to the blob. The signature is an HMAC computed over a string-to-sign and key using the SHA256 algorithm, and then encoded using Base64 encoding. |
Given that permissions are restricted to the service level, accessible operations with this SAS are Get Blob Service Properties (read) and Set Blob Service Properties (write). However, with a different resource URI, the same SAS token could also be used to delegate access to Get Blob Service Stats (read).
