public interface Attribute

An interface to an attribute associated with per-signer information.

Attributes are carried in the SignerInfo associated with each signer in a CMS SignedData. An attribute may be included in the signing process (obtainable via SignerInfo.getSignedAttributes()) or may be excluded (obtainable via SignerInfo.getUnsignedAttributes()).

Commonly used Attributes are defined in the atts sub-package.

Attribute is defined by the ASN.1 structure

    Attribute ::= SEQUENCE {
       attrType    OBJECT IDENTIFIER,
       attrValues  SET OF AttributeValue}

    AttributeValue :: ANY
