Verifying the integrity of the files
It is essential that you verify the integrity of the downloaded files using the PGP or MD5 signatures. Security of the mirrors cannot be guaranteed, which means malicious code could be added to the downloads from the mirrors. By verifying the integrity of downloaded release files, you ensure they have not been tainted.
Run the following command to verify the MD5 sum. It should give output similar to "apache-VCL-2.3.2.tar.bz2: OK":
md5sum -c apache-VCL-2.3.2.tar.bz2.md5
Similarly, run the following command to verify the SHA1 sum. You should get output similar to "apache-VCL-2.3.2.tar.bz2: OK":
sha1sum -c apache-VCL-2.3.2.tar.bz2.sha1
To verify the GPG signature (you'll need to have GnuPG installed):
download and import the VCL KEYS file (if you've imported the KEYS file for previously releases, you do not need to import it again):
gpg --import KEYS
download the GPG Signature to the same location as the release file
from the directory containing both the release file and the GPG signature, run
gpg --verify apache-VCL-2.3.2.tar.bz2.asc
