PwdHash2 de GWu

Automatically generates per-site passwords if you prefix your password with @@ or press F2 beforehand. Prevents JavaScript from reading your password as it is typed. The same password will be generated at each subdomain: a.example.com matches b.example.com, a.example.co.uk matches b.example.co.uk, but a.co.uk and b.co.uk are different.

This is based on the Stanford PwdHash add-on, main changes to the original:

1. Fixed defunct original version, caused by changes in Firefox 66.0.2 keypress event handling
2. Highlight password field, if active
3. Added option to change the hash algorithm from HMAC-MD5 to PBKDF2-SHA256 ( based on PwdHash-PoC )
4. Added option to store a user-specified salt and iteration count.
5. Added option to use legacy (Stanford PwdHash) mode by Shift-F2 or in the options

Hashed passwords can also be generated at https://gwuk.github.io/PwdHash2/
