  • Constructor Details

    • AuthorityKeyIdentifier

      protected AuthorityKeyIdentifier​(ASN1Sequence seq)

    • AuthorityKeyIdentifier

      public AuthorityKeyIdentifier​(SubjectPublicKeyInfo spki)
      Calulates the keyidentifier using a SHA1 hash over the BIT STRING from SubjectPublicKeyInfo as defined in RFC2459. Example of making a AuthorityKeyIdentifier: 
         SubjectPublicKeyInfo apki = new SubjectPublicKeyInfo((ASN1Sequence)new ASN1InputStream(
       publicKey.getEncoded()).readObject());
   AuthorityKeyIdentifier aki = new AuthorityKeyIdentifier(apki);

    • AuthorityKeyIdentifier

      public AuthorityKeyIdentifier​(SubjectPublicKeyInfo spki, GeneralNames name, BigInteger serialNumber)
      create an AuthorityKeyIdentifier with the GeneralNames tag and the serial number provided as well.

    • AuthorityKeyIdentifier

      public AuthorityKeyIdentifier​(GeneralNames name, BigInteger serialNumber)
      create an AuthorityKeyIdentifier with the GeneralNames tag and the serial number provided.

    • AuthorityKeyIdentifier

      public AuthorityKeyIdentifier​(byte[] keyIdentifier)
      create an AuthorityKeyIdentifier with a precomputed key identifier

    • AuthorityKeyIdentifier

      public AuthorityKeyIdentifier​(byte[] keyIdentifier, GeneralNames name, BigInteger serialNumber)
      create an AuthorityKeyIdentifier with a precomputed key identifier and the GeneralNames tag and the serial number provided as well.

    • toASN1Primitive

      public ASN1Primitive toASN1Primitive()
      Produce an object suitable for an ASN1OutputStream.
      Specified by:
      toASN1Primitive in interface ASN1Encodable
      Specified by:
      toASN1Primitive in class ASN1Object

    • toString

      public String toString()
      Description copied from class: Object
      Returns a string containing a concise, human-readable description of this object. Subclasses are encouraged to override this method and provide an implementation that takes into account the object's type and data. The default implementation is equivalent to the following expression: 
         getClass().getName() + '@' + Integer.toHexString(hashCode())

      See Writing a useful toString method if you intend implementing your own toString method.

      Overrides:
      toString in class Object
      Returns:
      a printable representation of this object.
