I want to load a KeyStore with the load method but when I use it I got an error. I don't understant what ECParameter is.

try {
FileInputStream is =new FileInputStream(new File("D:\\UZ\\key_privateUZ.p12"));
ks = KeyStore.getInstance("PKCS12");
password="1234".toCharArray();
ks.load(is, password);
} catch (Exception e) {
e.printStackTrace();
}

my error:

如果您进行搜索，您会发现大量有关 EC（椭圆曲线）参数的信息。特别是引发该异常的 JDK 代码。

如果您查看相关方法，您将在异常后看到一个注释掉的部分，表示：

它作为一个完整的解析实现的起点

换句话说，JDK 不支持所有可能的编码。

使用通常比基本 JDK 具有更多功能的Bouncy Castle可能会更好。

如果您解释密钥库中的数据是如何生成的，它也可能会有所帮助。

我解决了这个问题在 ECKey class ECParameterSpec papamSpec = ECNamedCurveTable.getParameterSpec(SECP);
