Verifying Downloads

It is highly recommended that you verify the files that you download.

We provide SHA digest files for all the files that we host on the download site. These files are named after the files they relate to but have .sha512 extensions.

We also provide PGP signature files that can be verified using PGP or GPG. These files are named after the files they relate to but have .asc.

Verifying Checksums

To verify the SHA digests, you need the .tgz and its associated .tgz.sha512 file. An example command:

sha512sum -c apache-pekko-sbt-paradox-1.0.1-incubating-src-20240305.tgz.sha512

Returns:

apache-pekko-sbt-paradox-1.0.1-incubating-src-20240305.tgz: OK

Verifying Signatures

To verify the PGP signatures, you will need to get the KEYS file. This will be in the source archive or can be fetched from https://downloads.apache.org/pekko/KEYS.

gpg --import KEYS

To verify the SHA digests, you need the .tgz and its associated .tgz.asc file. An example command:

gpg --verify apache-pekko-sbt-paradox-1.0.1-incubating-src-20240305.tgz.asc apache-pekko-sbt-paradox-1.0.1-incubating-src-20240305.tgz

Returns:
