Files placed in the Linux Kernel Archives are automatically OpenPGP-signed by the archive. This signature can be used to prove that a file, which may have been obtained from a mirror site or other location, really originated at the Linux Kernel Archives.

The current Linux Kernel Archives OpenPGP key is always posted here, including any revocation certificates which may be outstanding on older keys.

This signature does not guarantee that the Linux Kernel Archives master site itself has not been compromised. However, if we suffer an intrusion we will revoke the key and post information here as quickly as possible.

As of October 5, 1999 the Linux Kernel Archives PGP key is an OpenPGP-compliant DSS/Diffie-Hellman key. This key is compatible with all versions of GnuPG as well as PGP 5.0 or later.

Using GnuPG, verifying a signature should look like this:

% gpg --verify linux-2.3.9.tar.gz.sign linux-2.3.9.tar.gz
gpg: Signature made Tue Oct  5 17:40:50 1999 PDT using DSA key ID 1E1A8782
gpg: Good signature from "Linux Kernel Archives Verification Key "

Before you can do this, you must gpg --import the key below. This key is also available from most common PGP key servers, such as hkp://wwwkeys.pgp.net/ (http://wwwkeys.pgp.net:11371/pks/lookup?op=get&search=0x1E1A8782).

The previously used PGP 2.6 key has been revoked; see below for the revokation certificate.

The current Linux Kernel Archives OpenPGP key is:

pub  1024D/1E1A8782 1999-10-05 Linux Kernel Archives Verification Key <ftpadmin@kernel.org>
sub  2048g/BF890930 1999-10-05
