public RecipientKeyIdentifier(ASN1Sequence seq)

Deprecated. use getInstance()

Method Detail

getInstance

public static RecipientKeyIdentifier getInstance(ASN1TaggedObject ato,
                                 boolean isExplicit)

Return a RecipientKeyIdentifier object from a tagged object.

Parameters:

ato - the tagged object holding the object we want.

isExplicit - 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 RecipientKeyIdentifier getInstance(java.lang.Object obj)

Return a RecipientKeyIdentifier object from the given object.

Accepted inputs:

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

Parameters:

obj - the object we want converted.

Throws:

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

getSubjectKeyIdentifier

public ASN1OctetString getSubjectKeyIdentifier()

getDate

public ASN1GeneralizedTime getDate()

getOtherKeyAttribute

public OtherKeyAttribute getOtherKeyAttribute()

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.
