Shredo is a beautiful and functional file shredding utility.

1-pass
Offers good security and quickest erase of data. It deletes access information to your files and writes random bytes over the data ONCE.
7-pass
Slower speed, but better security than 1-pass.
Writes over data 7 times, based on US Department of Defence (DoD) 5220-20 M standard algorithms.
35-pass
Slowest, but offers best security.
Erases file access info and writes over the data 35 times, based on the Gutmann method for deletion.
