Subject: Update comments in aes.hpp
X-Git-Tag: optimized
X-Git-Url: https://www.irasnyder.com/gitweb/?a=commitdiff_plain;h=bde78677de357f04fd8bb6eac29a51433aa8a616;p=aes.git

Update comments in aes.hpp

This removes some redundant information from the comments in the aes.hpp
header file. Any C++ user should know that class constants can be set by
the constructor only, and then never again at runtime.
