----------------------------------
Summary: RarParser throws EncryptedDocumentException only when
whole archiveis encrypted
Key: TIKA-2818
URL: https://issues.apache.org/jira/browse/TIKA-2818
Project: Tika
Issue Type: Bug
Affects Versions: 1.20
Reporter: Pavel Arnošt
Attachments: rar4_encrypted_content_only.rar
RarParser throws EncryptedDocumentException only if whole archive is encrypted.
If encryption is on individial files, parser ends with
org.apache.tika.exception.TikaException: RarParser Exception:

File encryption should be checked before trying to extract content on line 79
like this:
FileHeader header = rar.nextFileHeader();
if (header.isEncrypted()) {
throw new EncryptedDocumentException();
}
while (header != null && !Thread.currentThread().isInterrupted()) {
Or maybe insert it into metadata with
TikaCoreProperties.TIKA_META_EXCEPTION_EMBEDDED_STREAM key? I don't know, but
current behaviour is not correct (parsing fails).
Sample document is attached.
