Do I need to know my file encryption type?

No. Uploading the file is enough. Our analyzer automatically identifies the container format and encryption profile within seconds. You do not need to know whether your file uses AES-256, ZipCrypto, RC4, or any other encryption standard.

Why are some old files guaranteed?

Certain legacy PDF (Adobe Acrobat 3-5) and Office (97-2003) formats use 40-bit RC4 encryption, which is cryptographically weak by modern standards. If analysis confirms an eligible profile, the documented legacy path may apply; treatment is confirmed per file and is not a blanket guarantee.

What if Fast Check does not find the password?

If Fast Check completes without finding your password, you can continue with Deep Recovery + AI. Your hints are converted into targeted candidate lists, and our GPU cluster runs millions of combinations per second. You only pay the activation fee to start Deep Recovery and the success fee if we find the password. If we exhaust all strategies, there is no success fee.

Can a random password manager password be recovered?

If it is long (12+ characters) and truly random (mixed case, numbers, symbols, no patterns), it is practically unrecoverable even with enterprise-grade hardware. Our service is strongest when the password has human structure: words, patterns, dates, or memorable phrases that can be predicted or reconstructed with hints.

Quick answer

The Password Recovery Problem

Every day, thousands of people lose access to their own files because they have forgotten a password. The file may be an old ZIP archive containing family photos, an Excel workbook with years of financial data locked behind a forgotten PIN, a PDF contract that cannot be opened, or a Word document with critical business information. The data is still there, intact — but the encryption key needed to access it is lost.

Recovery process

How it works

1
Upload and identify the format
The analyzer reads container metadata and encryption markers. This separates old Office from modern Office, ZipCrypto from AES ZIP, RAR3 from RAR5, and weak PDF generations from modern PDF. The detection step runs automatically within seconds of upload and determines which attack strategies will be effective.
2
Run the first practical path
Most standard files begin with a Fast Check for common passwords and quick wins. Eligible legacy PDF and Office cases can be routed directly to a guaranteed path after the file profile is confirmed. The exact candidate set and completion time depend on the format, queue, and current recovery policy; the result page shows the actual state when the scan completes.
3
Escalate with hints when needed
If the quick path misses, Deep Recovery + AI uses your remembered details to build dictionaries, masks, substitutions, and rule-based candidate lists. Hints such as possible words, years, name fragments, capitalization habits, and character substitutions allow our GPU cluster to focus on the most probable candidates rather than trying random guesses. This is the most common path for real-world recovery cases.

Supported systems and what changes by format

OFFICE: Word, Excel, PowerPoint · PDF: PDF documents · ARCHIVES: ZIP, RAR, 7z · SPECIAL: Wallets and hashes

DOC, XLS, and PPT from Office 97-2003 may use legacy encryption. DOCX, XLSX, and PPTX from modern Office usually use stronger AES-based protection where hints matter more.
Old Acrobat-era PDFs can fall into guaranteed recovery classes, while modern AES-protected PDFs depend on password strength and remembered details.
Classic ZipCrypto, WinZip AES, RAR3, RAR5, and 7-Zip AES-256 are treated as separate profiles because their testing speed and recovery outlook are different.
Selected wallet and hash-based workflows are handled only when the file can be identified and processed safely. Ownership and authorization matter.

Choosing the right recovery path

Best for simple, reused, or common passwords. It runs against every password base, mutation and date pattern for the file type. If a more complex candidate is found, the result page explains the available unlock or password-reveal option before payment.

Guaranteed legacy recovery: Used only after detection confirms an eligible weak legacy profile, such as some old PDF (Acrobat 3-5) or Office (97-2003) encryption classes. The guarantee depends on the verified encryption profile, not on the file extension or age alone.
Deep Recovery + AI: Used when the file is modern or the password is not found quickly. Your hints are turned into a focused search strategy instead of an unbounded random search. Success depends on the file profile, password structure, available hints, and the strategies that can be safely run for that case.

Common situations

Hints that improve Deep Recovery

Hints do not need to be perfect. A likely word, year, phrase style, symbol habit, language, or rough length can make a targeted search more relevant. Hints improve the search strategy, but they do not guarantee recovery and we do not promise a fixed uplift percentage.

Possible words, names, nicknames, company terms, document topics, or project names.
Years, dates, phone fragments, usernames, IDs, or numbers you often reuse.
Approximate length, known prefix or suffix, capitalization habits, and common symbols.
Old passwords that may have been reused with added digits or substitutions.
Language, keyboard layout, transliteration style, or whether it was typed on mobile.
Whether the password was human-made, shared by someone else, or generated by a password manager.
