I need to be certain that jce is available even in JRE environments out of the box. After furious googling I only managed to verify that jce comes bundled with the JDK after Java 1.4. Does the jce come bundled with the plain JRE download as well?
Could you point out where you found the information, so I can verify for myself and know what I missed?
yes, the jce is included in all versions of java these days, relevant announcement.
