Class X509KeyUsage

public class X509KeyUsage extends ASN1Encodable

A holding class for constructing an X509 Key Usage extension.

    id-ce-keyUsage OBJECT IDENTIFIER ::=  { id-ce 15 }

    KeyUsage ::= BIT STRING {
         digitalSignature        (0),
         nonRepudiation          (1),
         keyEncipherment         (2),
         dataEncipherment        (3),
         keyAgreement            (4),
         keyCertSign             (5),
