无法解密在 gnupg 中使用 openpgp-php 加密的文件

我已经用OpenPGP-PHP创建了一个公钥和私钥，然后我将它们都导入到GnuPG中，如果不指定"--allow-non-selfsigned-uid"标志，它不会导入公钥。然后，当我尝试解密文件时，我得到以下内容：

gpg --decrypt test.tif.asc 
Generated: Thu, 25 Feb 2016 11:12:28 -0500
gpg: unknown armor header: 
By:  <>
gpg: unknown armor header: 
Using: OpenPGP for PHP
gpg: unknown armor header: 
For: TEST
gpg: unknown armor header: 
gpg: encrypted with 512-bit RSA key, ID 519A1973, created 2016-02-25
      "TEST"
gpg: public key decryption failed: Wrong secret key used
gpg: decryption failed: No secret key

但关键显然存在：

gpg --list-secret-keys
/home/mike/.gnupg/secring.gpg
-----------------------------
sec    512R/519A1973 2016-02-25
uid                  TEST

我用PHP代码生成它们：

$header = array(
        'Generated' => date( "r" ),
        'By' => "Test <test@test.com>",
        'Using' => "OpenPGP for PHP",
        'For' => "TEST"
           );
$rsa = new Crypt_RSA();
$k = $rsa->createKey(512);
$rsa->loadKey( $k['privatekey'] );
$nkey = new OpenPGP_SecretKeyPacket(array(
            'n' => $rsa->modulus->toBytes(),
            'e' => $rsa->publicExponent->toBytes(),
            'd' => $rsa->exponent->toBytes(),
            'p' => $rsa->primes[1]->toBytes(),
            'q' => $rsa->primes[2]->toBytes(),
            'u' => $rsa->coefficients[2]->toBytes()
            ));
$uid = new OpenPGP_UserIDPacket( "TEST" );
$wkey = new OpenPGP_Crypt_RSA ($nkey );
$m = $wkey->sign_key_userid(array($nkey, $uid));
// Serialize private key
$private_bytes = $m->to_bytes();
$private_bytes = OpenPGP::enarmor( $private_bytes, "PGP PRIVATE KEY BLOCK", $header );
// Serialize public key message
$pubm = clone($m);
$pubm[0] = new OpenPGP_PublicKeyPacket($pubm[0]);
$public_bytes = OpenPGP::enarmor( $public_bytes, "PGP PUBLIC KEY BLOCK", $header );

并使用以下方法进行加密：

$pgp_header = array(
        'Generated' => date( "r" ),
        'By' => "Test <test@test.com>",
        'Using' => "OpenPGP for PHP",
        'For' => "TEST"
        );
// Unarmor the public key for encrypting
$public_bytes = OpenPGP_Message::parse( OpenPGP::unarmor( $public_bytes, "PGP PUBLIC KEY BLOCK" ) );
echo encryptData( file_get_contents( "test.tif" ), "test.tif", $public_bytes, $pgp_header );
function encryptData( $data, $filename, $key, $header )
{
    $data = new OpenPGP_LiteralDataPacket( $data, array('format' => 'u', 'filename' => $filename ) );
    $encrypted = OpenPGP_Crypt_Symmetric::encrypt( $key, new OpenPGP_Message(array($data)) );
    return( OpenPGP::enarmor( $encrypted->to_bytes(), "PGP MESSAGE", $header ) );
}

但似乎我肯定在某个地方错过了一些东西。我怎样才能让 GnuPG 成功解密我的东西？
