[Zlib-devel] Discussion about Zip Format

[Gilles Vollant]

Pehaps this is out of topic, but I just found several information about .Zip
format evolution (changement that break compatibility).
 
I found several article about this point :

PKWare new specification:
http://www.pkware.com/products/enterprise/white_papers/appnote.html
 
WinZip encryption specification:
http://www.winzip.com/aes_info.htm
 
 
And I discovered that PKWare include BZip2 as standard compression method
for .ZIP
I take a look at BZip2 library (at http://sources.redhat.com/bzip2/ ), and I
discovered this is a "zlib-like" library.
 
I just see that the bz_stream structure (a clone of z_stream) replace
total_in by total_in_lo32 and total_in_hi32 (same thing for total_out)
ftp://sources.redhat.com/pub/bzip2/docs/manual_3.html#SEC19
 
 
Do you known other compression library that clone zLib interface?
