Illegal key size问题
Illegal key size
在使用Cipher.init方法时突然报了一个异常java.security.InvalidKeyException: Illegal key size错误
java.security.InvalidKeyException: Illegal key size at javax.crypto.Cipher.checkCryptoPerm(Cipher.java:1039) at javax.crypto.Cipher.implInit(Cipher.java:805) at javax.crypto.Cipher.chooseProvider(Cipher.java:864) at javax.crypto.Cipher.init(Cipher.java:1396) at javax.crypto.Cipher.init(Cipher.java:1327)
下载后解压,将local_policy.jar和US_export_policy.jar以及readme.txt三个文件复制到JAVA_HOME/jre/lib/security目录下覆盖原来的文件
JDK7的下载地址: Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files 7 Download JDK8的下载地址: http://www.oracle.com/technetwork/java/javase/downloads/jce8-download-2133166.html
如何解决呢?需要去官方下载JCE无限制权限策略文件。
