Constructor Detail

### AuthorityKeyIdentifier

    public 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,
                                  java.math.BigInteger serialNumber)

  create an AuthorityKeyIdentifier with the GeneralNames tag and the serial number provided as well.

### AuthorityKeyIdentifier

    public AuthorityKeyIdentifier(GeneralNames name,
                                  java.math.BigInteger serialNumber)

  create an AuthorityKeyIdentifier with the GeneralNames tag and the serial number provided.

### AuthorityKeyIdentifier

    public AuthorityKeyIdentifier(byte[] keyIdentifier)

  create an AuthorityKeyIdentifier with a precomupted key identifier

### AuthorityKeyIdentifier

    public AuthorityKeyIdentifier(byte[] keyIdentifier,
                                  GeneralNames name,
                                  java.math.BigInteger serialNumber)

  create an AuthorityKeyIdentifier with a precomupted key identifier and the GeneralNames tag and the serial number provided as well.

Method Detail

### getInstance

    public static AuthorityKeyIdentifier getInstance(ASN1TaggedObject obj,
                                                     boolean explicit)

### getInstance

    public static AuthorityKeyIdentifier getInstance(java.lang.Object obj)

### getKeyIdentifier

    public byte[] getKeyIdentifier()

### getAuthorityCertIssuer

    public GeneralNames getAuthorityCertIssuer()

### getAuthorityCertSerialNumber

    public java.math.BigInteger getAuthorityCertSerialNumber()

### toASN1Object

    public DERObject toASN1Object()

  Produce an object suitable for an ASN1OutputStream.

  Specified by:
    `toASN1Object` in class `ASN1Encodable`

### toString

    public java.lang.String toString()

  Overrides:
    `toString` in class `java.lang.Object`
