zeroth approximation .. you need to eliminate the leading spaces in $2, no check is done to not to replace an already set "_" with another one, nor replacement of adjacent characters. Try



Code:
awk -F"\t" '
        {LEN = split ($2, T, "")
         $2 = ""
         for (i=1; i<=LEN/2; i++) T[int(rand()*LEN)] = "_"
         for (i=1; i<=LEN;   i++) $2 = $2 T[i]
        }

use Crypt::Random::Source::Factory; my $f = Crypt::Random::Source::Factory->new; my $strong = $f->get_strong; my $weak = $f->get_weak; my $any = $f->get; DESCRIPTION
This class implements a loading and instantiation factory for Crypt::Random::Source objects. If $ENV{CRYPT_RANDOM_NOT_PLUGGABLE} is set then only a preset list of sources will be tried. Otherwise Module::Find will be used to locate any installed sources, and use the first available one. METHODS
get %args Instantiate any random source, passing %args to the constructor. The "type" argument can be "weak", "strong" or "any". get_weak %args get_strong %args Instantiate a new weak or strong random source. AUTHOR
