Comment #4 on issue 1072 by ihab.awad: Provide support for signed Caja
modules
http://code.google.com/p/google-caja/issues/detail?id=1072
Interesting idea. I think I like it.
A disadvantage is that it requires the client to do a string *replace*
rather than a
mere string *truncate* in order to obtain the signed text. As you state, an
advantage
is that the signed text contains more of the structure, and a simple regex
can be
used to strip out the signature from the last line. A disadvantage is that,
to the
extent that this regex is simple, the verifier must split the module text
into lines
and reassemble.
Btw, we don't have to have *2* last lines; they could be merged into one:
signature: "..." });
