Workaround: Use pv (Pipe Viewer) to tee the decompressed stream to a temp file and to Hashcat simultaneously, but this defeats the purpose.

Do you have a specific or hardware setup you're trying to optimize for?
For example:
Using compressed wordlists directly within Hashcat solves this problem. It saves massive amounts of disk space and optimizes data delivery to your graphics processing units (GPUs). Why Use Compressed Wordlists?
Piping prevents Hashcat from performing "Dictionary cache building." Because the tool doesn't know the full length of the input, it cannot provide an accurate ETA or allow certain status features (like skipping/restoring) efficiently. 4. Performance Considerations
This approach works because Hashcat accepts wordlist input from standard input when no explicit wordlist file is provided. However, as noted earlier, this prevents Hashcat from building a dictionary cache, resulting in slower performance compared to the native method. hashcat compressed wordlist
Write a to automate cracking from multiple archives. Determine which compression level is best for your CPU.
Hashcat compressed wordlists offer a powerful way to optimize password cracking operations, providing significant benefits in terms of storage efficiency, transfer times, and performance. By creating and utilizing compressed wordlists, security professionals and penetration testers can streamline their workflow and improve the effectiveness of their password cracking efforts. Whether you're working with large wordlists or on storage-constrained devices, Hashcat compressed wordlists are an essential tool in the fight against password-protected security.
Hashcat natively detects and decompresses the following formats during the initial loading phase: Gzip (.gz) : Widely used for standard wordlists like rockyou.txt.gz ZIP (.zip) Workaround: Use pv (Pipe Viewer) to tee the
Smaller files make it significantly easier to transfer massive wordlists across cracking rigs or cloud instances. Does Hashcat Support Compressed Files Directly?
Compression formats like .gz or .7z reduce wordlist file sizes by up to 70% to 80%.
