加载应用程序属性时的加密异常(Java jasypt加密)

Question

尝试使用Maven安装模块时,会引发以下错误:

org.jasypt.exceptions.EncryptionOperationNotPossibleException:
Encryption raised an exception.
A possible cause is you are using strong encryption algorithms and you have not 
installed the Java Cryptography Extension (JCE) Unlimited Strength 
Jurisdiction Policy Files in this Java Virtual Machine

应用程序属性的编码如下:

app.check.url=ENC(sCO3322RNYdt3wPfO04GoaN9PijwJzUcn9rb4ggHymA\=)

我的弹簧配置如下所示:

我有jdk 1.7,它有加密所需的JCE文件.

有关如何解决此问题的任何想法？

Answer 1

你的问题不在于你没有JCE.你做.但是从您的配置中,您使用的是TripleDES算法,这需要安装JCE"Unlimited Strength Jurisdiction Policy files",如错误所示.

这些文件可以从Oracle的站点(从您下载JDK的同一页面)下载,并根据不同的许可协议分发,因为您必须确保您不是来自"禁止"的国家(伊朗,朝鲜等) )...

请参阅Jasypt常见问题解答中的这个问题:http://www.jasypt.org/faq.html#no-unlimited-strength

Answer 2

你没有安装jce,默认情况下存在于lib\security.但是它没有被访问或使用过.请下载jce文件并覆盖现有文件.查看你的错误本身you have not installed the Java Cryptography Extension (JCE)
