# 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
