hashcrack

Hash identification and lookup tool for CTF and security research.

hashcrack is a fast, feature-rich CLI tool for hash analysis in CTF competitions and security research. It auto-detects hash types (MD5, SHA-1, SHA-256, bcrypt, NTLM, and 20+ more), queries public hash databases, performs wordlist attacks, generates hashes, and provides deep statistical analysis — all with beautiful terminal output powered by Rich.

• Auto-detection — identifies 20+ hash types from MD5 to Argon2, bcrypt, NTLM, and scrypt
• Online lookup — queries multiple public hash cracking APIs simultaneously
• Wordlist attack — crack hashes locally using any wordlist (e.g. rockyou.txt)
• Hash generation — compute MD5, SHA-1, SHA-256, SHA-512, BLAKE2 and more in one command
• Batch mode — process hundreds of hashes from a file with optional auto-lookup
• Verification — confirm plaintext/hash pairs across all supported algorithms
• Deep analysis — entropy calculation, charset analysis, and type classification
• JSON output — every command supports --json for scripting and piping
