Which command sequence creates an MD5 rainbow table using ascii-32-95 and sorts it?

• A. rtgen sha1 ascii-32-95 1 20 0 1000 1000 0 and rtsort
• B. rtgen md5 ascii-32-95 1 20 0 1000 1000 0
• C. rtgen md5 ascii-32-95 1 10 0 500 500 0
• D. rtgen md5 ascii-33-126 1 20 0 1000 1000 0 and rtsort

Answer: (B)

This tests understanding of generating an MD5 rainbow table with a specific character set and length range. The choice uses the MD5 hash function, which is what you want for an MD5 rainbow table. It selects the character set ascii-32-95, which covers from space through the underscore, giving a broad mix of lowercase letters, digits, and common punctuation. The length range from 1 to 20 ensures you’re generating tables that cover short to moderately long passwords, a practical scope for rainbow-table creation. The remaining numerical parameters configure the chain length and number of chains to balance table size and coverage. After generation, you would typically run a sorting step with a tool like rtsort to optimize lookups, which is the standard follow-up in the workflow. The other options either switch to a different hash, use a different or narrower character set, or set a smaller maximum password length, making them less suitable for this particular MD5 + ascii-32-95 scenario.
