In Git 1.9.4, and its included gpg, I see silly error messages which can be eliminated by downloading iconv.dll and putting it in Git\bin\ and Git\libexec\git-core\:
gpg: error loading `iconv.dll': The specified module could not be found.
First, get the GnuPG public keys themselves from here. I saved that block to a file, and can check fingerprints like so:
>gpg --with-fingerprint gnupg.key
gpg: error loading `iconv.dll': The specified module could not be found.
gpg: please see http://www.gnupg.org/download/iconv.html for more information

And then imported:
>gpg --import gnupg.key
Second, now we can download libiconv-1.9.1.dll.zip (and the .sig file) from the GnuPG FTP server -- ftp://ftp.gnupg.org/gcrypt/binary/ -- and check the signature:
>gpg --verify libiconv-1.9.1.dll.zip.sig libiconv-1.9.1.dll.zip

gpg: please see http://www.gnupg.org/download/iconv.html for more information
gpg: Signature made 10/28/04 03:22:14 using DSA key ID 57548DCD
gpg: Good signature from "Werner Koch (gnupg sig) <dd9jn@gnu.org>"
gpg: Note: This key has expired!
Primary key fingerprint: 6BD9 050F D8FC 941B 4341 2DCC 68B7 AB89 5754 8DCD
Of course, that key is expired and so who knows WTF is going on and why Git doesn't just ship their own iconv.dll!
