/**
 * Provides classes for public key certificates.
 *
 * These classes include a simplified version of the
 * java.security.cert package.  These classes were developed
 * as part of the Java Secure Socket
 * Extension (JSSE).  When JSSE was added to the J2SE version 1.4, this
 * package was added for backward-compatibility reasons only.
 *
 * New applications should not use this package, but rather
 * java.security.cert.
 *
 * @since 1.4
