Passkeys & Infohas are reported invalid

I'm getting both of these. The first was invalid passkey when I had my torrent tracker set to mixed. After I switched it to public I was getting invalid infohash.
This is probably related to a problem with the generation of escaped codes passed in URLs not being 20 characters long.

Also this seems to be preventing the torrents from seeding (or there is another problem somewhere) thus making the module inoperable.

if (array_key_exists('passkey', $request)) {
if (strlen(urldecode($request['passkey'])) != 20) {
bt_message('Invalid passkey: '. $request['passkey'], BITTORRENT_MESSAGE_E$
}
}

if (strlen($request['info_hash']) != 20) {
bt_message('Invalid info_hash ('. strlen($request['info_hash']) .' - '. url$
}
