+# Monkeysphere Validation Agent #
+
+The Monkeysphere Validation Agent offers a local service for systems
+to validate certificates (both X.509 and OpenPGP) and other public
+keys in their proper contexts.  
+
+Among other reasons, having a validation agent is a good thing
+because:
+
+* Multiple tools can rely on the same PKI (e.g. the user's web browser
+  and the user's ssh client).
+* A single validation agent can present a consistent UI to the user
+  (when used in an end-user context), or provide a unified trust model
+  to various services (when used in a server-side context).
+* Authentication/certificate validation code can potentially be
+  isolated to a protected environment.
+ 
+## Implementations ##
+
+There are currently two implementations of the validation agent:
+
+ * msva-perl
+ * msva-ruby
+
+## Protocol ##
+
+The Monkeysphere Validation Agent protocol (MSVA) is defined as a
+minimal HTTP server with JSON-encapsulated requests and responses.
+You may want to read [more protocol details](protocol).

+
+# Validation Agent Protocol #
+
+In its current form, the
+[Monkeysphere Validation Agent](/validation-agent) is conceived of as
+a minimalistic HTTP server that accepts two different requests:
+
+ GET /  -- initial contact query, protocol version compatibility.
+  (no query parameters)
+  (returns: protoversion, server, available)
+
+ POST /reviewcert  -- request validation of a certificate
+  (query parameters: uid, context, pkc)
+  (returns: valid, message)
+
+Query parameters are posted as a JSON blob (*not* as
+www-form-encoded).
+
+The variables that are returned are application/json as well.
+
+* PKC means: public key carrier: raw key, OpenPGP cert, or X.509 cert
+* UID means: User ID (like in OpenPGP)
+* context refers to the setting in which the certificate is offered.  For example, "https" means: "this certificate was offered by an HTTPS server"
