If anybody uses this, please keep in mind the differences in security possibilities between native C code and Javascript.

Both this and GnuPG encrypt and decrypt data with PGP keys. GnuPG, however, does this securely, in many, many senses of the word. For instance, GnuPG maps all of its buffers to protected memory pages, and clears its buffers frequently and early.

A very large portion of GnuPG's code is dedicated to protecting your private keys, and the techniques that they use simply aren't available to javascript.

This doesn't mean the JS library is bad, it's just a good thing to keep in mind. Don't run your nuclear launch codes through this.
