11 years ago http://openpgpjs.org/ looks promising. (tested -> encrypt and decrypt works)
The question is, where to store the private key.
- in some file we have locally (if the passwords.html is always kept locally, we might be able to include this via an iframe / avoid cross site scripting problems) ?
Especially sharing / re-encrypting passwords would be much easier with a tight GPG integration into the browser.
There is the http://webpg.org/ pluging (FOSS) - what we would need is also a javascript API to invoke encryption / decryption and obtain the encrypted (or decrypted) text.
