How strong is 7z encryption?

7z uses AES-256 with a key derivation function that makes each password attempt computationally expensive. This is one of the strongest archive encryptions available, which is why powerful dedicated servers are essential for recovery.

How long does 7z password recovery take?

With our Deep Recovery + AI plan ($9.99 + $49.99 on success), most recoveries complete within 24 hours. Simple passwords are often found quickly. Complex passwords benefit significantly from password hints.

Can you recover 7z archives with encrypted filenames?

Yes. 7-Zip offers optional header encryption that hides filenames. Our recovery works the same regardless — we only need a small portion of the encrypted data to perform password recovery.

Why is 7z harder to crack than ZIP?

7z always uses AES-256 with strong key derivation, while many ZIP files use weaker ZipCrypto. This makes 7z significantly slower to process per password attempt. Our powerful servers compensate with massive parallel processing power.

Do password hints help with 7z recovery?

Yes, significantly. Because 7z encryption is slow to process, narrowing the search space with hints (keywords, length, character types) is especially valuable. It can reduce recovery time from days to hours.

Is my 7z archive safe during recovery?

We extract only the minimal encrypted header needed for password testing. Your actual files inside the archive are never accessed or stored. Customer content is deleted as soon as it is no longer needed and no later than 24 hours after upload. Terminal content is generally removed within 72 hours; delivery access may expire earlier.

Quick answer

A careful 7z recovery path

7z archives commonly use strong AES protection. Start with a file check, then use any password details you remember to decide whether a focused recovery attempt makes sense.

Recovery process

How it works

1
Upload Your 7z
Upload your password-protected 7z archive. We detect encryption settings and header encryption status.
2
Server-Powered Recovery
Our powerful servers attack the AES-256 encryption using optimized algorithms, smart wordlists, and pattern matching.
3
Get Your Password
Once found, you receive the password via email. You only pay if we find your password. Fast Check runs against every password base, mutation and date pattern for your file type.

Data Encryption

The file's data protection is identified first, so the recovery path reflects the archive you uploaded.

AES-256 encryption
Strong key derivation
LZMA2 compression

Header Encryption

Encrypted headers can hide archive details until access is recovered. Password clues help make a search more relevant.

Optional feature
Hides filenames
Same recovery process
