Locked out of a ZIP, RAR, PDF or Office file? We crack file passwords with GPU-accelerated attacks. Send the file — get the password.
Submit File →All ZIP encryption types: legacy ZipCrypto (fast, crackable in minutes with known-plaintext attacks) and WinZip AES-128/256 (modes 13600, 13000). AES-encrypted ZIPs require standard password attacks but are feasible.
RAR3 (mode 12500) uses AES-128 with iterated SHA-1. RAR5 (mode 13000) uses PBKDF2-HMAC-SHA256. Both are slow but weak passwords fall to dictionary and rule-based attacks. RAR5 is ~2x slower than RAR3.
7z uses AES-256 with SHA-256 key derivation (up to 2^19 iterations). Mode 11600. Computationally expensive, similar to RAR5.
PDF 1.1-1.3 (modes 10400/10500) use weak RC4 — crackable quickly. PDF 1.4-1.6 with 128-bit AES (mode 10600) are moderate. PDF 1.7+ with 256-bit AES (mode 10700) are strongest but still vulnerable to weak passwords.
Office 97-2003 (modes 9700-9800) — relatively weak, crackable quickly. Office 2007+ (modes 9400-9600) use AES with SHA iterations — slower. Office 2013+ (mode 9600) with 100,000 SHA-512 iterations is the hardest.
All files and archives: from $150 per file. Same price regardless of encryption type. No result = no charge.
For most archives, we only need the first few kilobytes (encryption header). For some formats, the full file is needed. We'll tell you after you contact us. Any password hints (partial knowledge, approximate length) increase feasibility.
