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
