The Windows version of Gnu Privacy Guard (GPG) stores keyrings for users under the directory
C:\Documents and Settings\username\Application Data\gnupgon a Windows XP system, where username is the username for the account under which the user logs into the system.
You can create new empty keyrings with
C:\Program Files\GNU\GnuPG>gpg --list-keys gpg: keyring `C:/Documents and Settings/JDoe/Application Data/gnupg\pubring.gpg ' created gpg: C:/Documents and Settings/JDoe/Application Data/gnupg\trustdb.gpg: trustdb created
Note: gpg uses the forward slash, "/", which is used on Unix, Linux, and other operating systems to separate directories, in its output, though Windows actually uses a backward slash, "\".
If you need to transfer keyrings from a Linux or Unix system to a Windows
system, the keyrings are likely to be stored in
on that system, i.e. in a
.gnupg beneath a user's home
directory. Transfer the
.gpg files, i.e. pubring.gpg,
To import someone's public key into the public keyring, you can use the instructions at Importing a Public Key with GPG.
