infgen is a deflate stream disassembler. It will read a gzip, zlib, or raw deflate stream, and output a readable description of the contents.
infgen permits the examination of deflate compressed data for instructional purposes, to see how the data is compressed, and for debugging deflate compressors.
Simply compile infgen.c, and provide the compressed data to stdin. The
disassembled output will be written to stdout. The zlib library needs to be
linked for CRC-32 functionality that is used on PNG input.
gzip < infgen.c | ./infgen
will display the disassembled result of compressing the infgen source code.
Use:
infgen -h
to see the command options.
A list of all of the command options and detailed technical documentation can be found in the comments at the start of infgen.c
