J2ME App有选择地在某些手机上运行

[英]J2ME App Selectively Working on Some Phones

原文 2013-03-22 18:57:25 4 2 java/ encryption/ java-me/ des

I'm currently working on a j2me app. 我目前正在开发j2me应用程序。 The app encrypts(using DES) and sends username and password to a server which then decrypts and authenticates the supplied credentials. 该应用程序加密（使用DES），并将用户名和密码发送到服务器，然后服务器解密并验证提供的凭据。 Tested it on a Nokia E63 and it worked well, but failed to work on some other phones that I tested it on like Bold 5 and LG C199. 在诺基亚E63上对其进行了测试，效果很好，但是在其他我测试过的手机（如Bold 5和LG C199）上却无法正常工作。 I tried debugging and found out that the program fails at the point where it instantiates the class responsible for the encryption. 我尝试调试，发现程序在实例化负责加密的类时失败。 Does anyone know how I can work around this? 有人知道我该如何解决吗？ Also is there anyway I can write a DES encryption without using the javax.crypto.Cipher class? 无论如何，是否可以不使用javax.crypto.Cipher类编写DES加密？

这些电话的某些jvm可能没有该类，请尝试在您的应用程序中显式添加该类

The bouncycastle lightweight crypto API comes in a j2me version . bouncycastle轻量级加密API带有j2me版本。 Be sure to read the FAQ about running an obfuscator on your j2me thingy (I don't know squat about j2me so you'll have to fill in the blanks). 请务必阅读有关在j2me上运行混淆器的常见问题解答（我不了解j2me，因此您必须填写空白）。
