JRE 8 rt.jar - javax.* Package Source Code

JRE 8 rt.jar is the JAR file for JRE 8 RT (Runtime) libraries. JRE (Java Runtime) 8 is the runtime environment included in JDK 8. JRE 8 rt.jar libraries are divided into 6 packages:

com.* - Internal Oracle and Sun Microsystems libraries
java.* - Standard Java API libraries.
javax.* - Extended Java API libraries.
jdk.* -  JDK supporting libraries.
org.* - Third party libraries.
sun.* - Old libraries developed by Sun Microsystems.

/**
 * <p>Abstract class for managing a variety of identity certificates.
 * An identity certificate is a guarantee by a principal that
 * a public key is that of another principal.  (A principal represents
 * an entity such as an individual user, a group, or a corporation.)
 *<p>
 * This class is an abstraction for certificates that have different
 * formats but important common uses.  For example, different types of
 * certificates, such as X.509 and PGP, share general certificate
 * functionality (like encoding and verifying) and
 * some types of information (like a public key).
 * <p>
 * X.509, PGP, and SDSI certificates can all be implemented by
 * subclassing the Certificate class, even though they contain different
 * sets of information, and they store and retrieve the information in
 * different ways.
 *
 * <p><em>Note: The classes in the package {@code javax.security.cert}
 * exist for compatibility with earlier versions of the
 * Java Secure Sockets Extension (JSSE). New applications should instead
 * use the standard Java SE certificate classes located in
 * {@code java.security.cert}.</em></p>
 *
 * @since 1.4
 * @see X509Certificate
