[jira] [Created] (NIFI-11437) Improve EncryptContentPGP Content Type Detection

David Handermann created NIFI-11437:
---------------------------------------

             Summary: Improve EncryptContentPGP Content Type Detection
                 Key: NIFI-11437
                 URL: https://issues.apache.org/jira/browse/NIFI-11437
             Project: Apache NiFi
          Issue Type: Improvement
          Components: Extensions, Security
            Reporter: David Handermann
            Assignee: David Handermann
             Fix For: 1.latest, 2.latest


The {{EncryptContentPGP}} Processor reads the initial bytes of incoming files to determine whether a file is an OpenPGP message. This initial read is necessary to support flows with {{SignContentPGP}} creating signed OpenPGP messages prior to encryption.

The current implementation uses an InputStreamCallback with ProcessSession.read() to run content type detection. Instead a separate read callback, the StreamCallback for ProcessSession.write() can be modified to use a buffer with {{{}PushbackInputStream{}}}. This will avoid reading the initial bytes multiple times.
