Android在密钥库中存储byte [] [英] Android store byte[] in the keystore

问题描述

我对密钥库非常困惑. 我发现了很多关于它的线索，但是没有任何用.我想在密钥库中存储和加载指定的密钥(byte []且未生成). 那行吗?我尝试了很多，但没有任何效果.

I'm very confused about the keystore. I found a lot threads about it but nothing works. I want to store and load a specified key (byte[] and not generated) in the keystore. Is that working? I tried a lot but nothing works.

您有一些代码片段吗?

Do you have some codesnippets?

谢谢 朱尔斯

KeyStore ks = KeyStore.getInstance("AndroidKeyStore");
ks.load(null);
ks.setEntry(alias, entry, param);
OutputStream writeStream = new FileOutputStream(path);
ks.store(writeStream, passwordForKey);
writeStream.close();

推荐答案

您必须使用Bas64编码(Android.util.Base64)将其存储为字符串. 没有存储原始字节数组的功能

You have to use Bas64-Encoding (Android.util.Base64) to store it as a string. There is no function to store a raw byte-Array
