# OnlineHashCrack

> OnlineHashCrack (OHC) is a cloud-based, GPU-accelerated password recovery and password-strength auditing platform for authorized security professionals (penetration testers, forensic analysts, sysadmins). Users submit hashes or protected files (including Office, WPA/WPA2, PDF, ZIP/RAR/7z, and Bitcoin/Ethereum wallets) via web or API, with support for 220 hash modes; OHC runs default cracking attacks and offers paid continuations for advanced strategies, priority GPU compute, custom wordlists, and per-hour brute-force jobs. Access requires tiered identity verification (email, phone/card, professional domain) and is restricted to lawful, authorized use only.

OHC is not a marketplace for unauthorized access. Usage is contingent on the Terms of Service, which prohibit cracking hashes or files without explicit authorization from the data owner.
