nanozlib

Nanoscale secure zlib decoding utilizing wuffs std/zlib, and somewhat secure zlib compression using stb'z lib, written in portable C/C++(Mostly C).

nanozib provides very limited zlib decoding and encoding functionalities. nanozib is good to embed zlib support to your C/C++ application.

Requirements

• C99, C++11 or later

Advantages and disadvantages

• Advantage(s)

  • Born to be super secure.
    • No assert, No C++ exception. No segfault for corrupted/malcious zlib data.

• Disadvantage(s)

  • Up to 2GB.
  • 50 KB or more in compiled binary(even compiled with -Os)
    • If you want picoscale zlib decoder, please take a look at zlib module in stb_image https://github.com/nothings/stb

Example

$ make
# 11 = uncompressed size
$ ./test_nanozdec test/test-000.txt.zz 11

Wuffs version

v0.3.0

TODO

• compress using wuffs or fpng's encoder. wuffs doesn't provide zlib encoding feature at the moment.
