[pgp] ユーザID(uid)の削除

GnuPGで登録済みのユーザIDを特定の鍵から削除する。パスフレーズが必要。

まずは現在の鍵の情報を確認。

$ gpg --list-key XXXXXXXX
pub   4096R/XXXXXXXX 2012-02-10
uid                  AYANOKOUZI, Ryuunosuke <i38w7i3@yahoo.co.jp>
uid                  AYANOKOUZI, Ryuunosuke
sub   4096R/YYYYYYYY 2012-02-10

この鍵からユーザID(uid)を削除。途中でこの鍵のパスフレーズを聞かれる。

$ gpg --edit-key XXXXXXXX
