-# der_chop ... this is one total hack that Eric is really not proud of
-# so don't look at it and don't ask for support
-#
-# The "documentation" for this (i.e. all the comments) are my fault --tjh
-#
-# This program takes the "raw" output of derparse/asn1parse and
-# converts it into tokens and then runs regular expression matches
-# to try to figure out what to grab to get the things that are needed
-# and it is possible that this will do the wrong thing as it is a *hack*
-#
-# SSLeay 0.5.2+ should have direct read support for x509 (via -inform NET)
-# [I know ... promises promises :-)]
-#
-# To convert a Netscape Certificate:
-# der_chop < ServerCert.der > cert.pem
-# To convert a Netscape Key (and encrypt it again to protect it)
-# rsa -inform NET -in ServerKey.der -des > key.pem
-#
-# 23-Apr-96 eay Added the extra ASN.1 string types, I still think this
-# is an evil hack. If nothing else the parsing should
-# be relative, not absolute.
-# 19-Apr-96 tjh hacked (with eay) into 0.5.x format
