We would like to protect the Azure Blob Storage access key in key vault. Which version of https://mvnrepository.com/artifact/org.apache.hadoop/hadoop-azure has support for such a capability, since the current support is not that secure.

Usage of Azure Blob Storage requires configuration of credentials. Typically this is set in core-site.xml. The configuration property name is of the form fs.azure.account.key..blob.core.windows.net and the value is the access key. The access key is a secret that protects access to your storage account. Do not share the access key (or the core-site.xml file) with an untrusted party.

<value>YOUR ACCESS KEY</value>
