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.

Accepted inputs:

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

Parameters:

obj - the object we want converted.

Throws:

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

getVersion

public ASN1Integer getVersion()

getKekid

public KEKIdentifier getKekid()

getKeyEncryptionAlgorithm

public AlgorithmIdentifier getKeyEncryptionAlgorithm()

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.
