使用Keytool将DES添加到密钥存储库

Question

我在java中实现了一个加密和解密器，它可以在密钥存储库文件上工作。我的密钥库已经有两个RSA的别名，但现在我需要添加DES。

有办法通过keytool做到这一点吗？我找不到任何地方可以做这件事。

Answer 1

keystore可以用来存储加密密钥，它使用的是PKCS12类型。示例代码取自https://www.pixelstech.net/article/1420427307-Difference-types-of-keystore-in-java----PKCS12

请注意，在本例中，sore和密钥输入密码存储在不安全的代码中。

    /*
    Store secret key
    PKCS12 allows to store secret keys on a limited base. Secret keys are frequently used to encrypt/decrypt data.
    To transfer the keys conveniently, they can be stored in a keystore like PKCS12 and transferred.
    Some secret keys with algorithm AES stored on PKCS12 keystore cannot be extracted in Java.
    Since PKCS12 is a portable standard, other libraries may support extracting secret keys.

    try {
        KeyStore keyStore = KeyStore.getInstance("PKCS12");
        keyStore.load(null, null);
        keyStore.load(new FileInputStream("pt_output.p12"), "password".toCharArray());

        KeyGenerator keyGen = KeyGenerator.getInstance("AES");
        keyGen.init(128);
        Key key = keyGen.generateKey();
        keyStore.setKeyEntry("secret", key, "password".toCharArray(), null);

        keyStore.store(new FileOutputStream("pt_output.p12"), "password".toCharArray());
    } catch (Exception ex) {
        ex.printStackTrace();
    }
