Class Extensions

  • All Implemented Interfaces:
    ASN1Encodable, Encodable
    public class Extensions
extends ASN1Object
         Extensions        ::=   SEQUENCE SIZE (1..MAX) OF Extension

     Extension         ::=   SEQUENCE {
        extnId            EXTENSION.&id ({ExtensionSet}),
        critical          BOOLEAN DEFAULT FALSE,
        extnValue         OCTET STRING }

    • Constructor Detail

      • Extensions

        public Extensions​(Extension extension)
        Base Constructor
        Parameters:
        extension - a single extension.

      • Extensions

        public Extensions​(Extension[] extensions)
        Base Constructor
        Parameters:
        extensions - an array of extensions.

    • Method Detail

      • getInstance

        public static Extensions getInstance​(java.lang.Object obj)

      • reviewStructure

        public static java.util.List reviewStructure​(ASN1Sequence seq)
        Re-run the parse of a candidate Extensions SEQUENCE collecting every problem the strict getInstance(...) path would have thrown (e.g. repeated extensions), instead of stopping at the first. The strict path and this share one parse method (see parse(org.bouncycastle.asn1.ASN1Sequence, java.util.List)); only the error sink differs. Intended for diagnostic/reporting tooling (github #1508); it does not relax the repeated-extension rule (the "org.bouncycastle.x509.ignore_repeated_extensions" property still governs whether a repeat is a problem at all).
        Parameters:
        seq - the candidate Extensions SEQUENCE.
        Returns:
        the exceptions the strict path would have thrown, one per problem, in parse order (empty if none).

      • oids

        public java.util.Enumeration oids()
        return an Enumeration of the extension field's object ids.

      • getExtension

        public Extension getExtension​(ASN1ObjectIdentifier oid)
        return the extension represented by the object identifier passed in.
        Returns:
        the extension if it's present, null otherwise.

      • getExtensionParsedValue

        public ASN1Encodable getExtensionParsedValue​(ASN1ObjectIdentifier oid)
        return the parsed value of the extension represented by the object identifier passed in.
        Returns:
        the parsed value of the extension if it's present, null otherwise.

      • getExtensionValue

        public ASN1OctetString getExtensionValue​(ASN1ObjectIdentifier oid)
        return the value of the extension represented by the object identifier passed in.
        Returns:
        the value of the extension if it's present, null otherwise.

      • toASN1Primitive

        public ASN1Primitive toASN1Primitive()
             Extensions        ::=   SEQUENCE SIZE (1..MAX) OF Extension

     Extension         ::=   SEQUENCE {
        extnId            EXTENSION.&id ({ExtensionSet}),
        critical          BOOLEAN DEFAULT FALSE,
        extnValue         OCTET STRING }
        Specified by:
        toASN1Primitive in interface ASN1Encodable
        Specified by:
        toASN1Primitive in class ASN1Object
        Returns:
        a primitive representation of this object.
