Question

我正在使用IBM Websphere 6 JRE来运行应用程序。我在尝试生成私钥时遇到错误

生成AES密钥Keysize：256

algorithm =“AES”，charset =“UTF8”，chiper =“AES / CBC / PKCS5Padding”，keyLen = 256;

Answer 1

应安装无限强度文件以解决此问题。在我的例子中也将java版本升级到JDK 7.

解决加密问题的步骤。
1）安装JDK 1.7 2）对于Java Projectin eclipse指向适用于编译器和运行时的正确JDK版本。 3）http://www.oracle.com/technetwork/java/javase/downloads/jce-7-download-432124.html

4）从上面的链接local_policy＆amp;中下载策略文件。 US_export_policy。
5）替换安全文件夹Ex：C：\ Program Files \ Java \ jdk1.7.0_79 \ jre \ lib \ security \和
下的java主目录中的策略文件 6）C：\ Program Files \ Java \ jre7 \ lib \ security \
7）现在重新启动websphere服务器并将两个策略文件放在java项目的类路径中。 8）程序应该生成Key＆amp;加密它。

Java安全性错误无法为受信任的CA Websphere 7设置证书
