It forms part of the Java <a href="Computer_security" title="Computer security">security</a> <a href="Application_programming_interface" class="mw-redirect" title="Application programming interface"> API</a>, and was first introduced in <a href="JDK" class="mw-redirect" title="JDK">JDK</a> 1.1 in the <code><a rel="nofollow" class="external text" href="https://docs.oracle.com/en/java/javase/24/docs/api/java.base/java/security/package-summary.html">java.security</a></code> package.
</p><p>The JCA uses a <a href="Provider_model" title="Provider model">"provider"-based architecture</a> and contains a set of APIs for various purposes, such as <a href="Encryption" title="Encryption">encryption</a>, <a href="Key_management" title="Key management">key generation and management</a>, <a href="Cryptographically_secure_pseudorandom_number_generator" title="Cryptographically secure pseudorandom number generator">secure random-number generation</a>, <a href="Public_key_certificate" title="Public key certificate">certificate validation</a>, etc. These APIs provide an easy way for <a href="Software_developer" class="mw-redirect" title="Software developer"> developers</a> to integrate security into application code.
