Constructor Detail

KEKIdentifier

public KEKIdentifier(byte[] keyIdentifier,
                     ASN1GeneralizedTime date,
                     OtherKeyAttribute other)

Method Detail

getInstance

public static KEKIdentifier getInstance(ASN1TaggedObject obj,
                                        boolean explicit)

Return a KEKIdentifier object from a tagged object.

Parameters:

obj - the tagged object holding the object we want.

explicit - true if the object is meant to be explicitly tagged false otherwise.

Throws:

java.lang.IllegalArgumentException - if the object held by the tagged object cannot be converted.

getInstance

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

Return a KEKIdentifier object from the given object.

Accepted inputs:

• null → null
• KEKIdentifier object
• ASN1Sequence input formats with KEKIdentifier structure inside

Parameters:

obj - the object we want converted.

Throws:

java.lang.IllegalArgumentException - if the object cannot be converted.

getKeyIdentifier

public ASN1OctetString getKeyIdentifier()

getDate

public ASN1GeneralizedTime getDate()

getOther

public OtherKeyAttribute getOther()

toASN1Primitive

public ASN1Primitive toASN1Primitive()

Produce an object suitable for an ASN1OutputStream.

Specified by:

toASN1Primitive in interface ASN1Encodable

Specified by:

toASN1Primitive in class ASN1Object

Returns:

a primitive representation of this object.
