 ContentInfo encapContentInfo,
 byte[] digest)

Method Details

getInstance

public static DigestedData getInstance(org.bouncycastle.asn1.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:

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

getInstance

public static DigestedData getInstance(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:

IllegalArgumentException - if the object cannot be converted.
