> 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.
