In their own words
lrzip
lrzip is a free GPL-2.0 command-line utility for compressing large files, usually above 10–50 MB. It first applies an extended rzip pass to reduce long-distance redundancy, then uses a backend such as LZMA, ZPAQ, LZO, GZIP, or BZIP2. Users can favor speed or smaller output, but not both simultaneously. Compression and decompression are heavily multithreaded, with CPU detection, and compression windows can use available RAM. Sliding mmap can exceed physical RAM but may be extremely slow. Encryption uses AES-256-GCM with PBKDF2-HMAC-SHA512 and HKDF; forgotten passwords cannot be recovered. The main program handles single files, while lrztar packages directories. It targets 64-bit Unix-like systems and supports macOS 10.5 or later from version 0.43. Building uses configure and make. Archive output is LRZ or TAR-compressed LRZ, with stable source releases on GitHub.
