Integrity Check

In order to check that the version of GnuPG which you are going to install is an original and unmodified one, you can do it in one of the following ways.


Using gpg

If you already have a trusted version of GnuPG installed, you can simply check the supplied signature. For example to check the signature of the file gnupg-1.2.6.tar.bz2 you would use this command:

gpg --verify gnupg-1.2.6.tar.bz2.sig

This checks whether the signature file matches the source file. You should see a message indicating that the signature is good and made by that signing key. Make sure that you have the right key, either by checking the fingerprint of that key with other sources or by checking that the key has been signed by a trustworthy other key.

Never use a GnuPG version you just downloaded to check the integrity of the source - use an existing GnuPG installation.


Using md5sum

If you are not able to use an old version of GnuPG, you have to verify the MD5 checksum. Assuming you downloaded the file gnupg-1.2.6.tar.bz2, you would run the md5sum command like this:

md5sum gnupg-1.2.6.tar.bz2

and check that the output matches the MD5 checksum reported on this site. An example of md5sum checksum is:

b1890f5dfacd2ba7ab15448c5ff08a4e gnupg-1.2.6.tar.bz2

If a SHA-1 checksum has been listed for the package and the command sha1sum is available on your system, you should prefer the SHA-1 checksum over MD5. Both commands are similar; sha1sum just uses a different algorithm and prints 8 more characters.
