why do you want to remove Blowfish related code ?

av_blowfish* is part of the public ABI/API of libavutil, so if you remove it
then your libavutil will not implement the ABI and that could break
applications using libavutil
within FFmpeg itself Blowfish is used in rtmpcrypt

thx

Rewriting code that is poorly written but fully understood is good.
Rewriting code that one doesnt understand is a sign that one is less smart
than the original author, trying to rewrite it will not make it better.
