Method Detail

getInstance

public static AuthEnvelopedData getInstance(ASN1TaggedObject obj,
                                            boolean explicit)

Return an AuthEnvelopedData object from a tagged object.

Accepted inputs:

• ASN1Sequence input formats

Parameters:

obj - the tagged object holding the object we want.

explicit - true if the object is meant to be explicitly tagged false otherwise.

Returns:

a reference that can be assigned to AuthEnvelopedData (may be null)

Throws:

java.lang.IllegalArgumentException - if the object held by the tagged object cannot be converted.

getInstance

public static AuthEnvelopedData getInstance(java.lang.Object obj)

Return an AuthEnvelopedData object from the given object.

Accepted inputs:

• null → null
• AuthEnvelopedData object
• org.bouncycastle.asn1.ASN1Sequence input formats with AuthEnvelopedData structure inside

Parameters:

obj - The object we want converted.

Returns:

a reference that can be assigned to AuthEnvelopedData (may be null)

Throws:

java.lang.IllegalArgumentException - if the object cannot be converted, or was null.
