JcaPEMWriter可以生成PKCS#8输出吗? [英] Can JcaPEMWriter generate PKCS#8 output?

问题描述

以下代码使用BouncyCastle中的JcaPEMWriter类以PKCS#1格式(-----BEGIN RSA PRIVATE KEY-----)输出随机生成的RSA私钥:

The following code uses the JcaPEMWriter class from BouncyCastle to output a randomly generated RSA private key in PKCS#1 format (-----BEGIN RSA PRIVATE KEY-----):

public static void main(String[] args) throws Exception {
    final KeyPairGenerator kpg = KeyPairGenerator.getInstance("RSA");
    kpg.initialize(2048, null);
    final KeyPair kp = kpg.generateKeyPair();
    final PrivateKey privateKey = kp.getPrivate();
    final StringWriter s = new StringWriter();
    try (JcaPEMWriter w = new JcaPEMWriter(s)) {
        w.writeObject(privateKey);
    }
    System.out.println(s);
}

有什么方法可以代替JcaPEMWriter输出PKCS#8格式(-----BEGIN PRIVATE KEY-----)?

Is there any way to make JcaPEMWriter output PKCS#8 format (-----BEGIN PRIVATE KEY-----) instead?

推荐答案

您需要向PEMWriter提供稍微不同的对象，即

You need to supply a slightly different object to the PEMWriter, namely a JcaPKCS8Generator. The following should work

try (JcaPEMWriter w = new JcaPEMWriter(s)) {
    w.writeObject(new JcaPKCS8Generator(privateKey, null));
}
