# 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
