public Class PKCS10Attribute

extends Object
implements DerEncoder
Class Inheritance
All Implemented Interfaces
sun.security.util.DerEncoder
Imports
java.io.IOException, sun.security.pkcs.PKCS9Attribute, sun.security.util.*
Represent a PKCS#10 Attribute.

Attributes are additional information which can be inserted in a PKCS#10 certificate request. For example a "Driving License Certificate" could have the driving license number as an attribute.

Attributes are represented as a sequence of the attribute identifier (Object Identifier) and a set of DER encoded attribute values. ASN.1 definition of Attribute: 

Attribute :: SEQUENCE {
   type    AttributeType,
   values  SET OF AttributeValue
}
AttributeType  ::= OBJECT IDENTIFIER
AttributeValue ::= ANY defined by type

Constructor Detail

PKCS10Attributeback to summary
public PKCS10Attribute(DerValue derVal) throws IOException

Constructs an attribute from a DER encoding. This constructor expects the value to be encoded as defined above, i.e. a SEQUENCE of OID and SET OF value(s), not a literal X.509 v3 extension. Only PKCS9 defined attributes are supported currently.

Parameters
derVal:DerValue

the der encoded attribute.

Exceptions
IOException:
on parsing errors.

public PKCS10Attribute(ObjectIdentifier attributeId, Object attributeValue)

Constructs an attribute from individual components of ObjectIdentifier and the value (any java object).

Parameters
attributeId:ObjectIdentifier

the ObjectIdentifier of the attribute.

attributeValue:Object

an instance of a class that implements the attribute identified by the ObjectIdentifier.

public PKCS10Attribute(PKCS9Attribute attr)

Constructs an attribute from PKCS9 attribute.

Parameters
attr:PKCS9Attribute

the PKCS9Attribute to create from.

public void encode(DerOutputStream out)

Implements sun.security.util.DerEncoder.encode.

DER encode this object onto an output stream. Implements the DerEncoder interface.

Parameters
out:DerOutputStream

the DerOutputStream on which to write the DER encoding.
