使用BouncyCastle加密文件，输出看起来已损坏

所以我用这段代码来加密我的文件

如您所见，IAM 使用公共 PGP

-----BEGIN PGP PUBLIC KEY BLOCK-----
Version: GnuPG v1.2.6 (GNU/Linux)
masdSFVkRBADYxPZYC+nu9nhSVkxcVkVJ5axZKzCRuygqUxka
kZIBy2CAQVKz5dBkRaUkaaksbcyautks7asaov26Fc9cT25Rvnh7
wYIJhcRoIl4cxashdgutasd0qfcOnVB5JVCQDhXclBW7kwCgkoUW
....
...
...
-----END PGP PUBLIC KEY BLOCK-----

代码工作正常，但我认为编码文件的数据已损坏

因为它不以这种格式出现(如密钥(

-----BEGIN PGP PUBLIC KEY BLOCK-----

我错了吗？

输出不应该是相同的格式吗？
