Verifying contents

All logback project artifacts published on Maven central are signed. For each artifact, there is an associated signature file with the .asc suffix.

The cryptographic key was updated 2022-08-08 to use a more modern Elliptic curve algorithm instead of RSA previously.

After 2022-08-08

To verify the signature use this public key. Here is its fingerprint:

pub   nistp521 2022-08-08 [SC]
      60200AC4AE761F1614D6C46766D68DAA073BE985
uid   Ceki Gulcu <ceki@qos.ch>
sub   nistp521 2022-08-08 [E]

A copy of this key is stored on the keys.openpgp.org keyserver. To add it to your public key ring use the following command:

Preventing commit history overwrite

In order to prevent loss of commit history, developers of the project are highly encouraged to deny branch deletions or history overwrites by invoking the following two commands on their local copy of the repository.

git config receive.denyDelete true
git config receive.denyNonFastForwards true
