Direct Known Subclasses:

SafeBag

public class Attributes

extends Object

This class implements attributes of SafeBags as defined in PKCS#12. At this time the following attributes are implemented:

• Friendly Name: String which holds a human readable name of the contents of the SafeBag.
• Local Key ID: Byte array which holds a key ID. This ID is used to specify corresponding certificate for a private key. This means this attribute is set for the KeyBag and the CertificateBag containing the corresponding certificate.

The ASN.1 definition looks like:

 Attributes ::= SET OF Attribute    -- from X.501
 

 -- in pre-1994 ASN.1, Attribute looks like:
 -- Attribute ::= SEQUENCE {
 --    type OBJECT IDENTIFIER,
 --    values SET OF ANY DEFINED BY type }
 

 FriendlyName ::= BMPString     -- a friendlyName has a single attr. value
 LocalKeyID   ::= OCTET STRING  -- a localKeyID has a single attr.value
 

Version:

File Revision 13
