Perhaps:

sub dashedHexToBytes{ 
    join'', map pack( 'H*', $_ ),split'-', $_[0] 
};;

[download]
print dashedHexToBytes( '3f-ff0c-1234-af12' );;
? ♀↕4»↕

Or

sub dashedHexToBytes{ 
    local $_ = shift; 
    tr[-][]; 
    return pack( 'h*', $_ );
};;

[download]
print dashedHexToBytes( '0123-4567-89ab-cdef-0123-4567-89ab-cdef' );;

Note: In both examples, you may need to switch from 'H*' to 'h*' or vice versa depending on the endianess of the originating system and that of the receiving system.

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
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.

The start of some sanity?
