org.apache.geronimo.util.asn1.x509
Class SubjectPublicKeyInfo

java.lang.Object
  extended by org.apache.geronimo.util.asn1.ASN1Encodable
      extended by org.apache.geronimo.util.asn1.x509.SubjectPublicKeyInfo
All Implemented Interfaces:
DEREncodable

public class SubjectPublicKeyInfo
extends ASN1Encodable

The object that contains the public key stored in a certficate.

The getEncoded() method in the public keys in the JCE produces a DER encoded one of these.

Method Detail

getInstance

public static SubjectPublicKeyInfo getInstance(ASN1TaggedObject obj,
                                               boolean explicit)

getInstance

public static SubjectPublicKeyInfo getInstance(Object obj)

getAlgorithmId

public AlgorithmIdentifier getAlgorithmId()

getPublicKey

public DERObject getPublicKey()
                       throws IOException
for when the public key is an encoded object - if the bitstring can't be decoded this routine throws an IOException.

Throws:
IOException - - if the bit string doesn't represent a DER encoded object.

getPublicKeyData

public DERBitString getPublicKeyData()
for when the public key is raw bits...


toASN1Object

public DERObject toASN1Object()
Produce an object suitable for an ASN1OutputStream.
 SubjectPublicKeyInfo ::= SEQUENCE {
                          algorithm AlgorithmIdentifier,
                          publicKey BIT STRING }
