I want to connect to Azure Blob Storage

Hi Stefan, 

I have a storage account for eg myaccount , a container mycontainer . 

I am using the URL https://myaccount.blob.core.windows.net/mycontainer/ where Note.png is a blob i am trying to get.

In the Headers I have 3 headers

• Authorization with Value "Shared Key myaccount:<hmacSignature>" where hmac signature is canonicalized signature created by following steps in azure documentation. in this hmac signature i am paaing the blob name , processing date and httpVerb.
• x-ms-date with Value hard coded date time every time i test or the now() function
• x-ms-version with Value 2015-04-05

and when i test this i come up with this error.
