Sorry, SC4 does not currently work with Microsoft Internet Explorer.
(SC4 also works with Chrome and Safari, but Firefox is a better choice
from a security point of view.)
Initializing... this should take less than one second. If you can actually
read this message, something has gone wrong.
You appear to have private browsing mode enabled. SC4 stores
important information (your encryption keys) in your browser's
localStorage, which is disabled when private browsing mode is turned
on, so SC4 won't work. To use SC4 please disable private browsing
mode and reload this page. If you are paranoid (and there's nothing wrong
with being paranoid where security is concerned) you can disconnect
from the network after you have re-loaded this page. SC4 is a
standalone application and does not require a network connection.

Welcome to SC4!
You are running this code from a local copy rather than
from a server. In order to be secure when running this way you need to
generate a customized version of SC4 that has your private keys embedded
within the code instead of being stored in your browser.
To generate a copy of SC4 that you can run from a local file
the resulting file and then open it in your browser. IMPORTANT: this file
will have your keys embedded within it, so don't share it with anyone!
NOTE: It is strongly recommended that you run this in Firefox or Chrome
and not Safari. This is because Safari discards the suggested file name
of locally generated downloads, but the file name needs to be randomized
in order to better secure the embedded keys.
