Java 中的 OpenPGP 公钥导入

Question

I trying to import a existint pgp public key:我试图导入一个现有的 pgp 公钥：

But my public key always is getting null value.但是我的公钥总是得到 null 值。 This public key is create with algoritm ecdsa,you can see the values used in this page: keyPropertes此公钥是使用算法 ecdsa 创建的，您可以查看此页面中使用的值： keyPropertes

This is my method to read the publicKey,it works if the algoritms to creaate the key is Rsa:这是我读取公钥的方法，如果创建密钥的算法是 Rsa，它就可以工作：

public static PGPPublicKey readPublicKey(InputStream in) throws IOException, PGPException {
        in = org.bouncycastle.openpgp.PGPUtil.getDecoderStream(in);

        PGPPublicKeyRingCollection pgpPub = new PGPPublicKeyRingCollection(in);

        //
        // we just loop through the collection till we find a key suitable for encryption, in the real
        // world you would probably want to be a bit smarter about this.
        //
        PGPPublicKey key = null;

        //
        // iterate through the key rings.
        //
        Iterator<PGPPublicKeyRing> rIt = pgpPub.getKeyRings();

        while (key == null && rIt.hasNext()) {
            PGPPublicKeyRing kRing = rIt.next();
            Iterator<PGPPublicKey> kIt = kRing.getPublicKeys();
            while (key == null && kIt.hasNext()) {
                PGPPublicKey k = kIt.next();

                if (k.isEncryptionKey()) {
                    key = k;
                }
            }
        }

        if (key == null) {
            throw new IllegalArgumentException("Can't find encryption key in key ring.");
        }

        return key;
    }

can you give me a big help with this?你能给我一个很大的帮助吗？

Thanks in advance, best regards;)在此先感谢，最好的问候；）

Your code is looking for an encryption-capable key.您的代码正在寻找具有加密功能的密钥。 All three keys in that keyblock are ECDSA (algorithm 19) which is only usable for signature verification, including 'certification' (key signing) and 'authorization' (SSH) both of which are actually kinds of signatures.该密钥块中的所有三个密钥都是 ECDSA（算法 19），仅可用于签名验证，包括“证书”（密钥签名）和“授权”（SSH），这两者实际上都是签名的一种。 If you truly want encryption you need an ECDH (algorithm 18) subkey.如果你真的想要加密，你需要一个ECDH （算法 18）子密钥。 See https://tools.ietf.org/html/rfc6637#section-5 .请参阅https://tools.ietf.org/html/rfc6637#section-5 。 If you truly want verification, you need to change your code.如果您真的想要验证，则需要更改您的代码。
