Class SubjectPublicKeyInfo

java.lang.Object
  |
  +--org.bouncycastle.asn1.x509.SubjectPublicKeyInfo
All Implemented Interfaces:
DEREncodable

public class SubjectPublicKeyInfo
extends java.lang.Object
implements DEREncodable

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.

for when the public key is raw bits...

getDERObject

public DERObject getDERObject()
 SubjectPublicKeyInfo ::= SEQUENCE {
