如何使我的 PGP 现代化？

我在 ubuntu 16.04 上，由于我的系统有点旧，所以我需要使用 GPG/TAILS PGP4USB GNUPG。

gpg --version
gpg (GnuPG) 1.4.20

Cipher: IDEA, 3DES, CAST5, BLOWFISH, AES, AES192, AES256, TWOFISH,
        CAMELLIA128, CAMELLIA192, CAMELLIA256

  1. 对我来说，解决这个问题最简单/最快的方法是什么？升级我的 ubuntu 能解决这个问题吗？我害怕升级，因为设置我的笔记本电脑可能需要一些时间（我使用 I3 并且有一堆硬件配置）。
  2. 那么 Kleopatra 或 Tails 等替代品怎么样？

谢谢！

对于 Ubuntu 16.04，gnupg软件包位于main存储库中，因此它仍然可以更新安全问题并可以安全使用。

对于新功能，您可以安装gnupg2在 16.04 中：

$ sudo apt install gnupg2
$ gpg2 --version
gpg (GnuPG) 2.1.11
libgcrypt 1.6.5
