+# OCSP request/response syntax

+# Derived from a minimal OCSP library (RFC2560) code written by
+# Bud P. Bruegger <bud@ancitel.it>
+# Copyright: Ancitel, S.p.a,  Rome, Italy
+# License: BSD
+#
+
+#
+# current limitations:
+# * request and response works only for a single certificate
+# * only some values are parsed out of the response
+# * the request does't set a nonce nor signature
+# * there is no signature validation of the response
+# * dates are left as strings in GeneralizedTime format -- datetime.datetime
+# would be nicer
