Constructor Detail

DigestedData

public DigestedData(AlgorithmIdentifier digestAlgorithm,
                    ContentInfo encapContentInfo,
                    byte[] digest)

Method Detail

getInstance

public static DigestedData getInstance(ASN1TaggedObject ato,
                                       boolean isExplicit)

Return a DigestedData object from a tagged object.

Parameters:

ato - the tagged object holding the object we want.

isExplicit - 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 DigestedData getInstance(java.lang.Object obj)

Return a DigestedData object from the given object.

Accepted inputs: null → null DigestedData object ASN1Sequence input formats

Parameters:

obj - the object we want converted.

Throws:

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

getVersion

public ASN1Integer getVersion()

getDigestAlgorithm

public AlgorithmIdentifier getDigestAlgorithm()

getEncapContentInfo

public ContentInfo getEncapContentInfo()

toASN1Primitive

public ASN1Primitive toASN1Primitive()

Description copied from class: ASN1Object

Method providing a primitive representation of this object suitable for encoding.

Overrides:

toASN1Primitive in class ASN1Object

Following copied from class: org.bouncycastle.asn1.ASN1Object

Returns:

a primitive representation of this object.

getDigest

public byte[] getDigest()
