This is a password generator. You can enter some input to the left boxes, and get some output to the right. Input labels are only a guide, you can enter whatever you want to.

Enter site name: Enter username: Enter phrase 1: Enter phrase 2:

Here is your output: Selectable (24): Length: 24 Length: 16 Length: 12 Length: 8

This system uses JavaScript code to generate hashes. It runs entirely in your browser. No information is transmitted over the internet. You can verify that by disconnecting your internet connection. You will still be able to run this tool properly.

Password = Hash ("Input1" + "Input2" + "Input3" + "Input4");

The hash function is a standard Sha-1 algorithm. The result is converted to 6-bit base with 64-character set "ABCDEFGHIJKLMNOPRSTUVXYZabcdefghijklmnoprstuvxyz0123456789-.+.-."

Some punctuation chars are used more than once to increase the frequency. This helps passwords contain more punctuation chars, and increase security. "w" and "q" chars are removed from the list.

JavaScript Sha-1 implementation is by Paul Johnston.
