Class java.security.cert.X509Certificate
This class represents certificates as defined in the X.509 standard.
Such certificates associate a public key with a subject, which is
usually a person or organization. You can find out the
certificate’s subject by calling getSubjectDN( ) while you can retrieve the subject’s public key
using getPublicKey( ). The certificate’s
issuer is the person or organization that generated and signed the
certificate (see getIssuerDN( )). If you have a
certificate file in the format described by RFC 1421, you can create
an X509Certificate from that data by using one of the
getInstance( ) methods.
