Using Compressed Wordlists with Hashcat Hashcat supports certain compressed file formats directly, allowing you to run attacks without manually extracting massive dictionaries. This is particularly useful for managing storage or when working with multi-terabyte wordlists. Supported Formats and Usage
Ironically, ZIP is the trickiest because unzip does not natively support stdout for binary safe streams in older versions. Use bsdtar (libarchive) or zstd for best results.
gunzip -c list.txt.gz | hashcat -m 2500 -r custom.rule handshake.hccapx - Use code with caution. The Slow-Hash Exception hashcat compressed wordlist
gunzip -c rockyou.txt.gz | head -n 10
: If you are using rules ( -r ), it is often more efficient to apply the rules after the words are piped from the compressed file. Use bsdtar (libarchive) or zstd for best results
hashcat -m 0 hashes.txt mangled.gz
The hashcat forum user royce performed a practical test demonstrating the workflow: hashcat -m 0 hashes
gzip --best large_wordlist.txt
