An in-browser decoder for RFC 4880 (aka PGP/GPG messages).
It doesn't decrypt anything, but it is useful for debugging the (rather obscure) packet format used by GnuPG and other PGP apps.
I'd recommend you use the version on my site at http://cirw.in/gpg-decoder/, but if you're debugging sensitive stuff and are really paranoid you might want to run it on a friendly web-server of your own.
There's a lot of RFC 4880, I mostly just implemented the bits I needed at the time. If you need anything added, please send a pull request :).
Massive thanks to Lapo Luchini for his work on the ASN.1 Javascript decoder.
