It automatically computes critical metrics that define a drug's performance, including: Cmaxcap C sub m a x end-sub

Previous versions of pktool were beloved for their simplicity but criticized for their limitations in high-scale environments. Version 2.0 addresses this with a completely rewritten core engine. By optimizing memory management and introducing multi-threaded processing, key generation and certificate signing operations are now reported to be up to 40% faster. pktool v2.0
The fundamental objective of the v2.0 upgrade was transforming user feedback from the global health research community into direct feature upgrades. Visual and Operational Refinements
For security analysts, introduces --forensic . In this mode, every captured packet is hashed (SHA-256) upon ingestion, and an index file is created separately from the raw PCAP. This allows you to rapidly verify integrity, deduplicate identical packets across large captures, and even search for a specific packet by its hash—something no other command-line tool offers natively. It automatically computes critical metrics that define a
Each decoded packet can be displayed in human-readable YAML, JSON, or classic tcpdump style.
