$ctx = Digest::CRC->new(type=>"crc32");;
print $ctx->add( pack 'H*', '50020301' )->hexdigest;;

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
