Technical Overview: Office Encryption

The Anatomy of Office Protection

Modern Microsoft Office documents (DOCX, XLSX, PPTX) use AES-128 or AES-256 encryption depending on the version. Unlike legacy binary formats (.doc, .xls) which relied on RC4, contemporary implementations hash passwords with SHA-512 over hundreds of thousands of iterations, making simple brute-force extraction computationally intensive.

How our recovery works

We extract the password hash structure from the uploaded file using the office2john tool, then run John the Ripper against curated wordlists optimised for Office documents. Typical Office-format files complete in seconds against a 10,000-entry dictionary.

    Volatile Processing Files never touch persistent storage. The hash is computed in memory, passed to John, and purged as soon as a result is returned.
