Constructor Detail

AlgorithmIdentifier

public AlgorithmIdentifier(OBJECT_IDENTIFIER oid)

Creates an AlgorithmIdentifier with no parameter.

AlgorithmIdentifier

public AlgorithmIdentifier(OBJECT_IDENTIFIER oid,
                           ASN1Value parameters)

Creates an AlgorithmIdentifier.

Parameters:

parameters - The algorithm parameters. A value of null will be encoded with an ASN.1 NULL.

Method Detail

getTag

public Tag getTag()

Description copied from interface: ASN1Value

Returns the base tag for this type, not counting any tags that may be imposed on it by its context.

Specified by:

getTag in interface ASN1Value

getOID

public OBJECT_IDENTIFIER getOID()

getParameters

public ASN1Value getParameters()

If this instance was constructed, returns the parameter passed in to the constructer. If this instance was decoded from a template, returns an ANY that was read from the BER stream. In either case, it will return null if no parameters were supplied.

getTemplate

public static AlgorithmIdentifier.Template getTemplate()

encode

public void encode(java.io.OutputStream ostream)
            throws java.io.IOException

Description copied from interface: ASN1Value

Write this value's DER encoding to an output stream using its own base tag.

Specified by:

encode in interface ASN1Value

Throws:

java.io.IOException

encode

public void encode(Tag implicit,
                   java.io.OutputStream ostream)
            throws java.io.IOException

Description copied from interface: ASN1Value

Write this value's DER encoding to an output stream using an implicit tag.

Specified by:

encode in interface ASN1Value

Throws:

java.io.IOException
