The library in question is designed for efficient decompression of GZIP archives, useful for both *.gz files and HTTP responses compressed using GZIP. Robustly tested on files containing up to 0.5 GB of text. It can automatically determine compression type by examining the fourth-byte flag, distinguishing between a compressed file and data from a site without filename metadata. Decompression expects data input in a char array format.

The primary function for decompression is CryptDecode(CRYPT_ARCH_ZIP, tmp, key, tx). It integrates a GZIP class for initial checks to confirm if data is GZIP compressed through its first three characters. Upon verification, one might choose from various unGZIP method overloads aimed at optimizing speed and memory usage. The decompressed data fills the char array tx, facilitating immediate processing by parsers like CSV o...
