Method Detail

getInstance

public static KEKRecipientInfo getInstance(ASN1TaggedObject obj,
                                           boolean explicit)

return a KEKRecipientInfo 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 KEKRecipientInfo getInstance(java.lang.Object obj)

return a KEKRecipientInfo object from the given object.

Parameters:

obj - the object we want converted.

Throws:

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

getVersion

public DERInteger getVersion()

getKekid

public KEKIdentifier getKekid()

getKeyEncryptionAlgorithm

public AlgorithmIdentifier getKeyEncryptionAlgorithm()

getEncryptedKey

public ASN1OctetString getEncryptedKey()

toASN1Object

public DERObject toASN1Object()

Produce an object suitable for an ASN1OutputStream.
