> ABFS: Support for Encryption Context
> ------------------------------------
>
> Key: HADOOP-17912
> URL: https://issues.apache.org/jira/browse/HADOOP-17912
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/azure
> Affects Versions: 3.3.1
> Reporter: Sumangala Patki
> Assignee: Pranav Saxena
> Priority: Major

> Support for customer-provided encryption keys at the file level, superceding
> the global (account-level) key use in HADOOP-17536.
> ABFS driver will support an "EncryptionContext" plugin for retrieving
> encryption information, the implementation for which should be provided by
> the client. The keys/context retrieved will be sent via request headers to
> the server, which will store the encryption context. Subsequent REST calls to
> server that access data/user metadata of the file will require fetching the
> encryption context through a GetFileProperties call and retrieving the key
> from the custom provider, before sending the request.
