SHA-1 is a one way hash. There isn't any reasonably efficient way to find
text that produces a particular hash. If you have a small set of possible
passwords, then you can try hashing them and seeing if you get the same
hash. However, you would need to know the details of how the original hash
was computed as it is common to include a salt to prevent people from
usefully compiling dictions of hashes for (relatively) common passwords.
