Why Extract a Hash?

A hash is a cryptographic signature derived from your password and the file's encryption metadata. It acts as a "checksum" for the password.

The Golden Rule of ForensicsYou do not need the original file to recover the password. The hash contains all the mathematical data required for our servers to brute-force the password. This is ideal for sensitive legal documents, medical records, or massive archives (10GB+).

Extraction Tools Reference

John the Ripper / Hashcat

We recommend using the standard *2john utilities.

Office Documents

DOCX, XLSX, PPTX

office2john.py

$ python office2john.py protected_doc.docx > hash.txt

Output Example:$office$*2013*100000*256*...

Requires Python installed. Works on all modern Office XML formats.

ZIP Archives

ZIP, ZIPX

zip2john

$ zip2john protected_archive.zip > hash.txt

Output Example:$pkzip2$1*1*2*0*...

Extracts hashes from legacy and AES-encrypted ZIP files.

RAR Archives

RAR, RAR5

rar2john

$ rar2john protected_archive.rar > hash.txt

Output Example:$rar5$16*...

Supports both RAR3 and new RAR5 header encryption.

PDF Documents

PDF

pdf2john.pl

$ perl pdf2john.pl secure_doc.pdf > hash.txt

Output Example:$pdf$2*105*...

Requires Perl. Supports standard 40-bit to 256-bit AES encryption.

Universal Process

Download Tools

Get the "Jumbo" version of John the Ripper from OpenWall or Hashcat binaries.

Run Command

Open your terminal/command prompt, navigate to the tool folder, and run the extraction command.

Upload Hash

Copy the output string (starting with $zip, $rar, etc.) and paste it into our recovery tool.

Have your hash?

We accept raw hashes directly.

Pro Tip

If you have a large archive (e.g. 50GB backup), extracting the hash is the only way to recover it efficiently. Uploading 50GB takes hours; uploading a hash takes milliseconds.
