Hi valvanp,

Do the contents of the file have to be in one $string?

If you can read the lines of the file into an array instead, it should take less processing time, as the regex won't have to scan (and modify) one huge, single line each time.

s''(q.S:$/9=(T1';s;(..)(..);$..=substr+crypt($1,$2),2,3;eg;print$..$/
