我已经在谷歌上搜索了几个小时，但找不到任何可靠的答案，但有很多传闻。

有谁知道定义 Android 操作系统支持哪些加密/签名/哈希算法的文档在哪里。

我从论坛上听说并非所有手机都支持相同的算法，所以我正在寻找每部 Android 手机都支持的通用算法。

Answer 1

试试这个列出所有安全提供者:

Provider[] providers = Security.getProviders();
for (Provider provider : providers) {
    Log.i("CRYPTO","provider: "+provider.getName());
    Set<Provider.Service> services = provider.getServices();
    for (Provider.Service service : services) {
        Log.i("CRYPTO","  algorithm: "+service.getAlgorithm());
    }
}
