-------------------------------------------
Hi,
I'm trying to configure BlobStoreContext for Azure storage using SAS token. I
found the below code snippet from [jclouds
|https://jclouds.apache.org/guides/azure-storage/]site that offers the portable
BlobStore api:
{code:java}
BlobStoreContext context = ContextBuilder.newBuilder("azureblob")
.credentials(storageAccountName, sasToken) //using sasToken in place of
storage key
.buildView(BlobStoreContext.class);
{code}
Since we use SAS token based authentication, so I used sasToken in place of
storageKey in the above code. But this throws :
*com.google.common.io.BaseEncoding$DecodingException: Invalid input length 121*
Please find the full stack trace attached for your reference.
I could be wrong, but after following the test class
[SharedKeyLiteAuthenticationTest.java|https://gitbox.apache.org/repos/asf?p=jclouds.git;a=blob;f=providers/azureblob/src/test/java/org/jclouds/azure/storage/filters/SharedKeyLiteAuthenticationTest.java;h=5e0c2264127a2665c70391f010c6031fabe27854;hb=0ce9261]
which was committed as a part of the
[PR|https://gitbox.apache.org/repos/asf?p=jclouds.git;h=0ce9261], I tried the
below code of my own:
{code:java}
BlobStoreContext context = ContextBuilder.newBuilder("azureblob")
.endpoint("https://${identity}.blob.core.windows.net";)
.credentials(accountName, sasToken)
.modules(new ArrayList<>(3)) //just added an empty list of
size 3
.buildInjector()
.getInstance(BlobStoreContext.class);
{code}
The above code also throws the same exception.
Is it right to use SAS token as credential in place of storage key ?
Is it possible to use SAS token to configure BlobStoreContext for azure in
order to get the portable BlobStore ?
A code snippet would be highly appreciated.
Thanks and Regards,
Biswa Ranjan Ray

> Hi,
> We have one use case where we want to provide limited access to objects in
> our storage accounts. We figured that the best way to do this is by using
> SAS token based authentication mechanism to upload/download objects to Azure
> Blob Storage - [SAS based
> Authentication|https://docs.microsoft.com/en-us/azure/storage/common/storage-dotnet-shared-access-signature-part-1]
> We found that JClouds client library provides support for Azure Blob Storage
> using account keys which might not fit our use case because of security
> reasons.
