hashcat utils, and the "Expander"

[mastercracker]

And in case you ask for it later, OclHashcat-plus don't have a left and right but you can always make a second wordlist modified by inserting $ in front of every letter of every word and use it as a rule (right equivalent) file. For example a wordlist with Insert and Password, you would modify it to:

$I$n$s$e$r$t
$P$a$s$s$w$o$r$d
