Figuring out salt from SHA1

[fahmid]

Is there a way I can figure out the salt used from the SHA1 hash using Hashcat?

Thanks!

Wait, if you have a salted hash, that salt is a always known because it can't be a secret. Otherwise you simply exported it wrong.

Just a shot in the dark here, but he is probably referring to one of the Tumblr or Dropbox hashes.  Those were salted SHA1 hashes with no salt included, hence the question.

The -e switch, for specifying a salt list, may actually have utility after all.
