Why Password Length Beats Symbol Complexity
Modern GPU clusters can calculate billions of NTLM and MD5 hashes per second. An 8-character password with numbers and symbols can be cracked in minutes.
However, increasing length to 16 characters increases the combinatorial search space to over $94^{16} \approx 3.7 \times 10^{31}$ possibilities—requiring billions of years to crack even with supercomputers.
