java - 我一直在使用 Bouncy Castle API 为字节 [] 进行 PGP 加密和解密，并收到“无效盔甲”错误消息

Question

我一直在使用充气城堡 API 在 Java 中进行 PGP 加密/解密工作一段时间，并且我在处理文件方面取得了成功，但我需要使用 inputStream/byte 数组，但我在这样做时遇到了问题。使用以下代码，加密工作没有任何问题。但是对于解密，我遇到了“Invalid Armor”错误，请参阅下面的错误消息。我在谷歌上搜索过，在任何地方都找不到类似的错误。任何帮助将非常感激。让我知道我需要在我的代码中修复什么。我还使用 PGPUtil 类来转换/读取公钥和私钥。

错误：

这是我的代码：
