java.lang.Object
org.mozilla.jss.netscape.security.x509.Attribute
All Implemented Interfaces:
Serializable, DerEncoder

public final class Attribute extends Object implements Serializable, DerEncoder
An attribute, as identified by some attribute ID, has some particular values. Values are as a rule ASN.1 printable strings. A conventional set of type IDs is recognized when parsing. The following shows the syntax:

    Attribute   ::= SEQUENCE {
 type           AttributeType,
        value           SET OF AttributeValue
                -- at least one value is required --}

    AttributeType       ::= OBJECT IDENTIFIER

    AttributeValue      ::= ANY

 
Refer to draft-ietf-pkix-ipki-part1-11 for the support attributes listed on page 96 of the internet draft. The are listed here for easy reference: name, common name, surname, given name, initials, generation qualifier, dn qualifier, country name, locality name, state or province name, organization name, organization unit name, title, pkcs9 email. Not all the attributes are supported. Please check the X500NameAttrMap for defined attributes.
