In other words, you can stick to CPU based cracking if you want such a feature. But then it makes no more sense to add it to oclHashcat.

So there's no way to do a hash like this?
base64(md5(base64(sha1(md5(base64(password))))))

a petty that this can't be implemented

If this is from something that is used widely, then yes. Create a trac ticket with all the pertinent information. If this is some app that 5 people use, no. There are far more important things for us to work on.

You could however write your own plugin for jtr, or ask halfie or magnum to do it for you.
