| Tool | Actual Mechanism | Crack Rate (NTLM) | Limitations | |------|----------------|------------------|--------------| | Hashcat | Brute-force, dictionary, rules | up to 90 GH/s (8x RTX 4090) | Time for strong passwords | | John the Ripper | Similar + Markov mode | 50-80 GH/s | Uses CPU and GPU | | Ophcrack | Rainbow tables (LM only, not NTLM) | Seconds for LM | Useless for modern NTLM | | Online “decrypters” | Precomputed lookup of common hashes | Instant for weak passwords | Fails for unique passwords |
Here’s a feature set for a tool called — understanding that NTLM hashes can’t be “decrypted” (they’re one-way), so the tool actually focuses on cracking, reversing via lookup, or analyzing them. ntlm-hash-decrypter
If you have an NTLM hash and need the original password, you can use these common approaches: | Tool | Actual Mechanism | Crack Rate
