Everybody knows you don't store plain text passwords in a database,
you store hashes instead
consider:
userpass = getpass.getpass("User password? ")
encuserpass = hashlib.md5()
encuserpass.update(userpass)
del userpass
Now the documentation clearly states that if you are hashing a string

According to documentation on the python.org site it should be as simple as

hashname = hashlib.sha234 (or whatever other hash method you want
like md5 or whatever)
hashname.up
