SExprParser.parseSecretKey:java.io.IOException:遇到未知字符：K

我正在尝试使用bouncy castlebcprov-jdk15on-1.66.jar从D:\Users\xxxxx\AppData\Roaming\gnupg\private-keys-v1.D加载密钥

import java.io.BufferedInputStream;

            PBEProtectionRemoverFactory passphraseProvider = new JcePBEProtectionRemoverFactory(
                pass.toCharArray());
        InputStream in = new FileInputStream(filePath);


        PGPSecretKey key =

        new SExprParser(calculatorProvider).parseSecretKey(
                new BufferedInputStream(in), passphraseProvider,
                new JcaKeyFingerprintCalculator());

        System.out.println("Found key "
                + Hex.toHexString(key.getPublicKey().getFingerprint()));
            
        
    }
}

但是我越来越

线程“main”java.io.IOException中出现异常：遇到未知字符：K 在org.bouncycastle.gpg.SXprUtils.skipoppenincorlations（未知来源） 在org.bouncycastle.gpg.sexprprpparser.parseSecretKey（未知来源）

gpg（GnuPG）2.2.23

libgcrypt 1.8.6

在我看来，SExprParse只接受“原始”pgp密钥，而不接受“PEM”密钥

我的示例中的密钥取自Bouncy Castle SExprTest.java，因此它是一个带有密码“fred”的示例密钥

由于密钥是二进制形式，我使用

ByteArrayInputStream

来处理密钥，这是指向完整测试的链接：

程序正在成功运行，并最终显示一个密钥：

Found key 228f5c0cd3e1d2716760770be5ac9684b1a77195

也许我们的一位蹦蹦跳跳城堡专家能更好地解释这种行为

代码如下：

你好，Michael Fehr，非常感谢您的回复。但是我们的想法是为给定的用户加载私钥。我的代码在GNUPG版本2.1.X中运行良好，因为它引发了GNUPG版本2.2.X的异常。也许您可以编辑您的问题，并将带有GNUPG版本2.2.X的示例密钥与密码短语一起附加？
