您可以手动向 PGP public 密钥块添加注释而不破坏它吗？

Question

假定以下是有效的 PGP PUBLIC 密钥块:

我是否可以如下图所示手动添加评论——例如，使用 vim——并且它仍然有效？我知道我可以重新运行 gpg(1) 命令来执行此操作，但我手头没有它。

谢谢。

Answer 1

是的，有效，

-----BEGIN PGP PUBLIC KEY BLOCK-----
Version: SKS 1.1.6+
Comment: Hostname: pgp.key-server.io

如上所述，经常使用评论和版本标签，包括其他标签，根据 RFC4880，允许 Armor Header Keys 包括：

 - "Version", which states the OpenPGP implementation and version
   used to encode the message.

 - "Comment", a user-defined comment.  OpenPGP defines all text to
   be in UTF-8.  A comment may be any UTF-8 string.  However, the
   whole point of armoring is to provide seven-bit-clean data.
   Consequently, if a comment has characters that are outside the
   US-ASCII range of UTF, they may very well not survive transport.

 - "MessageID", a 32-character string of printable characters.  The
   string must be the same for all parts of a multi-part message
   that uses the "PART X" Armor Header.  MessageID strings should be
   unique enough that the recipient of the mail can associate all
   the parts of a message with each other.  A good checksum or
   cryptographic hash function is sufficient.

   The MessageID SHOULD NOT appear unless it is in a multi-part
   message.  If it appears at all, it MUST be computed from the
   finished (encrypted, signed, etc.) message in a deterministic
   fashion, rather than contain a purely random value.  This is to
   allow the legitimate recipient to determine that the MessageID
   cannot serve as a covert means of leaking cryptographic key
   information.

 - "Hash", a comma-separated list of hash algorithms used in this
   message.  This is used only in cleartext signed messages.

 - "Charset", a description of the character set that the plaintext
   is in.  Please note that OpenPGP defines text to be in UTF-8.  An
   implementation will get best results by translating into and out
   of UTF-8.  However, there are many instances where this is easier
   said than done.  Also, there are communities of users who have no
   need for UTF-8 because they are all happy with a character set
   like ISO Latin-5 or a Japanese character set.  In such instances,
   an implementation MAY override the UTF-8 default by using this
   header key.  An implementation MAY implement this key and any
   translations it cares to; an implementation MAY ignore it and
   assume all text is UTF-8.

Can you manually add a comment to a PGP public key block and not break it?
