          SecurePage - make self-decrypting web pages

SecurePage encrypts an HTML page and adds a JavaScript wrapper,
making a new page that can be decrypted by any web browser given
the correct passphrase.  In some cases this method may be preferable
to server-side security.

To use it, you just give the cleartext HTML file as stdin and get
the encrypted HTML file as stdout.  The decryption passphrase is
given as a command-line argument.  Then send out only the encrypted
HTML file, and tell your readers the passphrase.  Without the
passphrase, the file is not readable; with it, the file decrypts
and displays itself.

You could distribute the encrypted HTML file via a web site, a CD-
ROM/DVD, email, whatever.  Since it doesn't depend on a web server
for security, any transmission method will work.

See the manual entry for more details.
