问题

使用Bouncy Castle加密的邮件将被gpg版本2解密，但是没有gpg版本1的错误。

问题

我认为我的Java代码中缺少一部分，但这次我不知道什么是缺失的。
这里的gpg版本1和版本2有什么区别？

加密GnuPG消息

以下Java类将消息加密为PGP加密消息：

@Test
public void testEncryptPGP() throws Exception {
    GnuPG gpg = new GnuPG();
    String res = gpg.encryptPGP(pgpKey, msg);

    System.out.println(res);
}

这个小junit做了一个简单的测试来加密“Hello world！”

HttpResponseRedirect

使用gpg2进行解密会导致臭名昭着的无效数据包错误，但邮件将被解密。

    $ LANG=C gpg2 -vvvv -d xxx.asc > xxx.txt

    gpg: decryption failed: Invalid packet

现在与gpg版本1相同 - 没有错误。

    gpg: using character set iso-8859-1
    gpg: armor: BEGIN PGP MESSAGE
    gpg: armor header: Version: BCPG v1.53
    :pubkey enc packet: version 3, algo 1, keyid ***
        data: [4096 bits]
    gpg: public key is ***

    You need a passphrase to unlock the secret key for
    user: "Hostmaster <hostmaster@example.com>"
    4096-bit RSA key, ID ***, created 2013-09-01

    gpg: public key encrypted data: good DEK
    :encrypted data packet:
        length: 4137
        mdc_method: 2
    gpg: encrypted with 4096-bit RSA key, ID ***, created 2013-09-01
          "Hostmaster <hostmaster@example.com>"
    gpg: AES256 encrypted data
    :compressed packet: algo=1
    :literal data packet:
        mode b (62), created 1450355926, name="_CONSOLE",
        raw data: 12 bytes
    gpg: NOTE: sender requested "for-your-eyes-only"
    gpg: decryption okay

gpg2解密失败：无效数据包但如果用gpg1解密则没有错误
