Checking the integrity of sources
Kernel source integrity can be checked through OpenPGP digital signatures.
Full details on
If needed, read and create a new private and public keypair for yourself.
Import the public GnuPG key of kernel developers:
gpg --keyserver pgp.mit.edu --recv-keys 0x517D0F0E
If blocked by your firewall, look for 0x517D0F0E on
, copy and paste the key to a linuxkey.txt file: gpg --import linuxkey.txt
Check the signature of files:
gpg --verify linux2.6.11.12.tar.bz2.sign
