Name
Class java.security.cert.X509Certificate
Synopsis
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.
