this webpage is a self-contained program for computing secure password choices using a keyed message authentication code. it is copyright (C) 1999 vengeance software, written by graydon hoare and released under the terms of the GNU general public license v2.0+

to operate it, key the first field with your passphrase (it is not stored nor sent anywhere outside your browser, honest -- read the code), then enter the name of the facility, site, URL, etc. that you want to make a password for in the second field. press the button, and a password will pop up in the 3rd field. It will always compute the same password, and it's quite hard for anyone to figure out the passphrase from the generated password (they would need a way through SHA-1).
