While there isn't a single "academic paper" exclusively dedicated to the specific feature of compressed wordlists in Hashcat, the functionality is a core technical feature documented in Hashcat's official source code and discussed in professional recovery contexts. Technical Overview
If your goal is saving space while targeting fast hashes, standard compression might not be the best route. Instead, consider generating a .hcstat2 file for or Hybrid attacks.

: Hashcat still performs its initial analysis to build dictionary statistics. For extremely large compressed files, this startup phase (reading 90-98%) may take several minutes or even hours depending on your drive speed. Troubleshooting Common Issues
Use for the fastest decompression speeds on Linux systems. Instead, consider generating a
Reading a smaller file from a storage medium (even NVMe) can sometimes be faster than reading a massive, uncompressed file, especially if the drive is bottlenecked.
Native decompression typically has no noticeable performance loss during the cracking phase. However, there is a startup delay (from minutes to hours for terabyte-scale lists) because Hashcat must decompress the file once to calculate statistics and build the dictionary cache.
