in reply to What's your favourite method of untainting?

For those who are unaware, the untainting method described in the third option refers specifically to tainting behaviour for hash keys - That is, hash keys are not tainted, ever. From perlsec - Because taintedness is associated with each scalar value, some elements of an array or hash can be tainted and others not. The keys of a hash are never tainted.

 

perl -le "print unpack'N', pack'B32', '00000000000000000000001000000000'"

    As per WikiPedia Taint means
    in computer science, in particular in the Perl programming language, "tainted" data are considered untrusted and are treated with caution
    Some Guru may want to add some more information to it, since it is described in a short manner.
