Well, Enigform can send your public key to the remote server automatically (well, at least *MY* version does, the public release will have a wizard/submenu/somethinglikethat) and mod_auth_openpgp can import it automatically
The method for key import is triggered when a POST request for /HTTP_OPENPGP_IMPORTKEY is received. Of course, the post payload is the ascii-armored public key. I've thought of using the binary one, but ascii is better for debugging.
The next step is to implement encryption/decryption, server-side signed responses, and port mod_ssl's passphrase handling features into m_a_o.
The other news is that Dinis Cruz told me today that the latest developments, which I reported to him directly, enable me to receive 50% of the OWASP Sponsorship money
