Appendix A Component Labels

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

Label Component OID

C countryName
CN commonName
DC domainComponent 0.9.2342.19200300.100.1.25
L localityName
O organizationName
OU organizationalUnit
ST stateOrProvince
STREET streetAddress
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
BC businessCategory
D description
EMAIL emailAddress 1.2.840.113549.1.9.1
GN givenName
PSEUDO pseudonym
SN surname
T title
