GPG—无效标记包

GPG—无效标记包

有人能帮助解决以下 gpg 问题吗?尝试解密一个非常旧的 gpg 加密文件(我认为它是一个 zip 存档)失败,并显示简单的“无效标记包”。尝试 --list-packets 会给出以下不错的输出:

gpg: invalid marker packet
gpg: [don't know]: invalid packet (ctb=1d)

有没有办法可以克服“无效标记包”错误?

答案1

这看起来更像是您的文件已损坏,而 GnuPG 识别的数据包类型实际上是随机数据。常规加密文件没有这么多数据包,而且许多值没有任何意义。

如果它是一个有效的 PGP 加密文件,GnuPG至少已经认出了其中的一切。
