GnuPG。文件大小限制？

Question

使用 GnuPG(1.0.xx,2.0.xx,2.1.xx) 加密单个文件是否有文件大小限制？
文件大小范围从大约 2GiB 到 100GiB。我并不担心 2GiB，但我不确定加密单个 100GiB 文件是否是个好主意。如果我这样做会遇到问题吗？或者加密如此大的文件是否完全安全？我检查了https://gnupg.org/
上的常见问题解答，只找到了一篇涉及不同密码的文件大小限制的文章，但如果程序本身存在限制则没有。以下是具体部分的链接： https://gnupg.org/faq/gnupg-faq.html#recommended_ciphers

亲切的问候

文件大小限制取决于操作系统。

--max-output n
                 This option sets a limit on the number of bytes that will  be
                 generated  when  processing  a  file.  Since OpenPGP supports
                 various levels of compression, it is possible that the plain-
                 text  of a given message may be significantly larger than the
                 original OpenPGP message.  While GnuPG  works  properly  with
                 such  messages, there is often a desire to set a maximum file
                 size that will be generated before processing  is  forced  to
                 stop  by  the  OS  limits.   Defaults  to  0, which means "no
                 limit".
