# OpenSSL example configuration file.
# This is mostly being used for generation of certificate requests.
#
# The openssl configuration file consists of attribute/value pairs.
# These pairs are delimited by an '=' (equals sign).  The left
# hand side is the name or attribute.  The right hand side is
# the value that the attribute represents.
#
# Some attribute value pairs serve as section identifiers.
# Those which do in this example file are:
# oid_section
# default_ca
# policy
# distinguished_name
# attributes
# req_extensions
# crl_extensions
#  
# section identifiers are denoted with a string composed of alphanumeric
# characters and underscores enclosed in brackets ([])
#
# For example:
# [ section_identifier ]
#
# Sections end when an new section identifier occurs or when EOF (end of file)
# is encountered.
#
# two sections that don't have attribute value pairs are:
# [ ca ]   (Parameters for the Certificate Authority that this configuration file describes)
# [ req ]  (Parameters for generating certificate requests)
#
# For more information consult the config(5) man page installed by openssl

# begin default section

# This definition stops the following lines choking if HOME isn't
# defined.
HOME			= .

# file which contains random bytes to seed openssl's RNG
RANDFILE		= \$ENV::HOME/.rnd


# Extra OBJECT IDENTIFIER info:
#oid_file		= \$ENV::HOME/.oid
oid_section		= new_oids

# To use this configuration file with the "-extfile" option of the
# "openssl x509" utility, name here the section containing the
# X.509v3 extensions to use:
# extensions		= 
# (Alternatively, use a configuration file that has only
# X.509v3 extensions in its main [= default] section.)

# end default section

[ new_oids ]

# An Object Identifier (OID) is the name of an object in Abstract Syntax
# Notation 1 (ASN1).  OIDs allow you to address or refer to
# an object.
#
# A root OID is unique to an organization or entity.
# Root OIDs aren't necessary for experimentation or development,
# They probably aren't needed for most persons who use openssl.
#
# You can learn how to register for a Root OID if you are in the US at:
# http://www.ansi.org/public/services/reg_org.html
#
# If you are outside the US you can find out where to register for
# your country at:
# http://www.iso.ch/addresse/membodies.html
#
# We can add new OIDs in here for use by 'ca' and 'req'.
# Add a simple OID like this:
# testoid1=1.2.3.4
# Or use config file substitution like this:
# testoid2=\${testoid1}.5.6
