SubjectPublicKeyInfo

extends ASN1Encodable
java.lang.Object
   ↳ org.bouncycastle.asn1.ASN1Encodable
     ↳ org.bouncycastle.asn1.x509.SubjectPublicKeyInfo

Class Overview

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.
