[steghide-devel] Program speed (buffer size)

[Joergen P. <Jor...@hu...>]

Hello.

Last week, I tried using steghide to embed a secret message into a very large 
(30MB) WAV-file with good results (sort of). The problem was, that for files 
of this size, program execution takes several hours even on +1 GHz 
processors. This makes steghide unsuitable for hiding data inside audio CD:s.

Fortunately, this can be easily fixed: I changed the buffer size from 10240 
bytes to 256 kbytes, and the program executed in a few minutes! The "right" 
solution would of course be to make reading and writing sequential files 
smarter, but as an interim fix, I propose a larger default buffer size in the 
order of something like 64 kbytes.
