Deprecated. use getInstance()

Method Detail

getInstance

public static EnvelopedData getInstance(ASN1TaggedObject obj,
                        boolean explicit)

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

Return an EnvelopedData object from the given object.

Accepted inputs:

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

Parameters:

obj - the object we want converted.

Throws:

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

getVersion

public ASN1Integer getVersion()

getOriginatorInfo

public OriginatorInfo getOriginatorInfo()

getRecipientInfos

public ASN1Set getRecipientInfos()

getEncryptedContentInfo

public EncryptedContentInfo getEncryptedContentInfo()

getUnprotectedAttrs

public ASN1Set getUnprotectedAttrs()

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.

calculateVersion

public static int calculateVersion(OriginatorInfo originatorInfo,
                   ASN1Set recipientInfos,
                   ASN1Set unprotectedAttrs)
