Appendix A Component Labels

RFC-2253 defines the following table with string representations of name components:

Label Component OID

C countryName 2.5.4.6
CN commonName 2.5.4.3
DC domainComponent 0.9.2342.19200300.100.1.25
L localityName 2.5.4.7
O organizationName 2.5.4.10
OU organizationalUnit 2.5.4.11
ST stateOrProvince 2.5.4.8
STREET streetAddress 2.5.4.9
UID userid 0.9.2342.19200300.100.1.1

They are used internally for converting a DN into its string representation; components not listed in this table will be represented by their OID.

For the other direction, i.e. creating a DN from the string representation, KSBA recognizes the following extra labels:

Label Component OID

ADDR postalAddress 2.5.4.16
