# == ASN.1 Definition
#
# The following is the formal definition of OIDs specified in this file.
#
# puppetCertExtensions OBJECT IDENTIFIER ::= {iso(1) identified-organization(3)
#    dod(6) internet(1) private(4) enterprise(1) 34380 1}
#
# -- the tree under registeredExtensions 'belongs' to puppetlabs
# -- privateExtensions can be extended by enterprises to suit their own needs
# registeredExtensions OBJECT IDENTIFIER ::= { puppetCertExtensions 1 }
# privateExtensions OBJECT IDENTIFIER ::= { puppetCertExtensions 2 }
#
# -- subtree of common registered extensions
# -- The short names for these OIDs are intentionally lowercased and formatted
# -- since they may be exposed inside the Puppet DSL as variables.
# pp_uuid  OBJECT IDENTIFIER ::= { registeredExtensions 1 }
# pp_instance_id OBJECT IDENTIFIER ::= { registeredExtensions 2 }
# pp_image_name OBJECT IDENTIFIER ::= { registeredExtensions 3 }
# pp_preshared_key OBJECT IDENTIFIER ::= { registeredExtensions 4 }
