KEKRecipientInfo

public KEKRecipientInfo(org.bouncycastle.asn1.ASN1Sequence seq)

Method Detail

getInstance

public static KEKRecipientInfo getInstance(org.bouncycastle.asn1.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.
