## Verifying Releases

It is essential that you verify the integrity of the downloaded files using the PGP and MD5 signatures. MD5 verification ensures the file was not corrupted during the download process. PGP verification ensures that the file came from a certain person.

The PGP signatures can be verified using PGP or GPG. First download the Apache Derby KEYS as well as the `asc` signature file for the particular distribution. It is important that you get these files from the ultimate trusted source - the main ASF distribution site, rather than from a mirror. Then verify the signatures using ...

    % pgpk -a KEYS
    % pgpv db-derby-X.Y.tar.gz.asc

    or

    % pgp -ka KEYS
    % pgp db-derby-X.Y.tar.gz.asc

    or

    % gpg --import KEYS
    % gpg --verify db-derby-X.Y.tar.gz.asc

To verify the MD5 signature on the files, you need to use a program called `md5` or `md5sum`, which is included in many unix distributions. It is also available as part of GNU Textutils. Windows users can get binary md5 programs from here, here, or here.

We strongly recommend that you verify your downloads with both PGP and MD5.
