Method Detail

getInstance

public static RecipientEncryptedKey getInstance(ASN1TaggedObject obj,
                                                boolean explicit)

Return an RecipientEncryptedKey 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 RecipientEncryptedKey getInstance(java.lang.Object obj)

Return a RecipientEncryptedKey object from the given object.

Accepted inputs:

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

Parameters:

obj - the object we want converted.

Throws:

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

getIdentifier

public KeyAgreeRecipientIdentifier getIdentifier()

getEncryptedKey

public ASN1OctetString getEncryptedKey()

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.
