JavaFX将加密的图像文件加载到ImageView中
[英]JavaFX Loading encrypted image file into ImageView
问题描述
I have some encrypted image files with AES, i would like to load these images into image view in my gui. 
我有一些使用AES加密的图像文件，我想将这些图像加载到GUI中的图像视图中。 However, i do not want them accessable without my gui, that decrypting them into different file is not solution for me because decrypted images can be taken while the gui is showing them. 但是，我不希望没有gui即可访问它们，将它们解密成其他文件对我来说不是解决方案，因为可以在gui显示它们的同时获取解密的图像。 What should I do? 我该怎么办？

Use CipherInputStream to create a stream of deciphered image, then create a BufferedImage from CipherInputStream . 使用CipherInputStream创建解密的图像流，然后从CipherInputStream创建一个BufferedImage 。 Add BufferedImage to your image component. 将BufferedImage添加到您的图像组件。 If your key is larger than 128 bit you have to install jce. 如果密钥大于128位，则必须安装jce。
