Class C509Extensions

java.lang.Object
org.bouncycastle.cbor.c509.C509Extensions
public class C509Extensions extends Object
The C509 extensions field (Section 3.1.10 of draft-ietf-cose-cbor-encoded-cert-20): 
Extensions = [ * Extension ] / int
An omitted X.509 extensions field is an empty CBOR array. When the only extension present is an int-coded keyUsage, the array is elided and the field is a single CBOR int whose absolute value is the keyUsage value and whose sign is the criticality.

    • fromX509Extensions

      public static C509Extensions fromX509Extensions(org.bouncycastle.asn1.x509.Extensions x509Extensions)
      Build the C509 form of a set of X.509 extensions. Extensions in the C509 Extensions Registry whose values the specific CBOR encodings of Section 3.3 can faithfully represent use the int-coded form; everything else is carried in the generic ~oid form. Passing null (an absent X.509 extensions field) yields an empty extension list.

    • size

      public int size()
      Return the number of extensions.

    • getExtension

      public C509Extension getExtension(int index)
      Return the extension at the given index, in certificate order.

    • toX509Extensions

      public org.bouncycastle.asn1.x509.Extensions toX509Extensions()
      Return the X.509 view of the extensions, or null when there are none (an omitted X.509 extensions field).
