hashcat Forum

Is it possible to crack an encrypted odt file using hashcat? Or how would one go about doing it.

I found several documents online about how open document files are encrypted, but I couldn't figure out how to use hashcat to find the password.

When I extract the odt file I found that it contained the following content in the manifest.xml file:

Code:
<manifest:manifest xmlns:manifest="urn:oasis:names:tc:opendocument:xmlns:manifest:1.0" manifest:version="1.2">

<manifest:file-entry manifest:full-path="/" manifest:version="1.2" manifest:media-type="application/vnd.oasis.opendocument.text"/>

<manifest:file-entry manifest:full-path="content.xml" manifest:media-type="text/xml" manifest:size="4680">

 <manifest:encryption-data manifest:checksum-type="urn:oasis:names:tc:opendocument:xmlns:manifest:1.0#sha256-1k" manifest:checksum="s+g9HtqoVZZymr2ImwF3aC5eOEnemsrJVR2YiMeYHt8=">

  <manifest:algorithm manifest:algorithm-name="http://www.w3.org/2001/04/xmlenc#aes256-cbc" manifest:initialisation-vector="edJhIRt0sLfBmbIMaHYjxA=="/>

  <manifest:key-derivation manifest:key-derivation-name="PBKDF2" manifest:key-size="32" manifest:iteration-count="1024" manifest:salt="DXG+zcdMzxmblxZCs2uUTQ=="/>

  <manifest:start-key-generation manifest:start-key-generation-name="http://www.w3.org/2000/09/xmldsig#sha256" manifest:key-size="32"/>

 </manifest:encryption-data>

</manifest:file-entry>

Here is the password protected odt file if someone wants to try and crack it. If you are able to figure out a way of using hashcat to crack the password please let me know how.

There's a request for adding support here: https://github.com/hashcat/hashcat/issues/101
