Class SPKAC

java.lang.Object
oracle.security.crypto.cert.SPKAC

All Implemented Interfaces:

java.io.Externalizable, java.io.Serializable, oracle.security.crypto.asn1.ASN1Object, oracle.security.crypto.util.Streamable

public class SPKAC

extends java.lang.Object

implements oracle.security.crypto.asn1.ASN1Object, java.io.Externalizable

An implementation of Signed Public Key And Challenge (SPKAC), which is used by Netscape Navigator browser to request certificates.

The SPKAC class can be used by the X509 class to generate X509 certificates.

Constructor Detail

SPKAC

public SPKAC()

Creates a new empty instance. This constructor is to be used with serialization or with the input method.

SPKAC

public SPKAC(oracle.security.crypto.core.KeyPair kp)

Creates a new SPKAC. Sets the challenge to an empty string.

SPKAC

public SPKAC(oracle.security.crypto.core.KeyPair kp,
             oracle.security.crypto.core.RandomBitsSource rbs)

Creates a new SPKAC. Sets the challenge to an empty string.

Parameters:

kp - the key pair

rbs - the random bits source to be used for the signing operation, if needed

SPKAC

public SPKAC(java.lang.String challenge,
             oracle.security.crypto.core.KeyPair kp)
