 2.1.4.2 Signature Checking Using `GnuPG'
 ........................................
 
 Another method of verifying the integrity and authenticity of a package
 is to use cryptographic signatures. This is more reliable than using
 MD5 checksums, but requires more work.
 
 At MySQL AB, we sign MySQL downloadable packages with `GnuPG' (GNU
 Privacy Guard).  `GnuPG' is an Open Source alternative to the
 well-known Pretty Good Privacy (`PGP') by Phil Zimmermann. See
 `http://www.gnupg.org/' for more information about `GnuPG' and how to
 obtain and install it on your system. Most Linux distributions ship
 with `GnuPG' installed by default. For more information about `GnuPG',
 see `http://www.openpgp.org/'.
 
 To verify the signature for a specific package, you first need to
 obtain a copy of MySQL AB's public GPG build key, which you can
 download from `http://www.keyserver.net/'.  The key that you want to
 obtain is named `build@mysql.com'. Alternatively, you can cut and paste
 the key directly from the following text:
 
      Key ID:
      pub  1024D/5072E1F5 2003-02-03
           MySQL Package signing key (www.mysql.com) <build@mysql.com>
      Fingerprint: A4A9 4068 76FC BD3C 4567  70C8 8C71 8D3B 5072 E1F5
 
      Public Key (ASCII-armored):

      -----END PGP PUBLIC KEY BLOCK-----
 
 To import the build key into your personal public GPG keyring, use `gpg
 --import'. For example, if you have saved the key in a file named
 `mysql_pubkey.asc', the import command looks like this:
 
      shell> gpg --import mysql_pubkey.asc
 
 After you have downloaded and imported the public build key, download
 your desired MySQL package and the corresponding signature, which also
 is available from the download page. The signature file has the same
 name as the distribution file with an `.asc' extension. For example:
 
 Distribution   `mysql-standard-5.0.19-linux-i686.tar.gz'
 file           
 Signature file `mysql-standard-5.0.19-linux-i686.tar.gz.asc'
 
 Make sure that both files are stored in the same directory and then run
 the following command to verify the signature for the distribution file:
 
      shell> gpg --verify PACKAGE_NAME.asc
 
 Example:
 
      shell> gpg --verify mysql-standard-5.0.19-linux-i686.tar.gz.asc
      gpg: Signature made Tue 12 Jul 2005 23:35:41 EST using DSA key ID 5072E1F5
      gpg: Good signature from "MySQL Package signing key (www.mysql.com) <build@mysql.com>"
 
 The `Good signature' message indicates that everything is all right.
 You can ignore any `insecure memory' warning you might obtain.
 
 See the GPG documentation for more information on how to work with
 public keys.
