Fix detection of invalid SSH key algorithm

Verify that the OpenSSH key algorithm matches the one
associated with the public key. Throw a new specific
InvalidKeyAlgorithmException if the two algorithms do not match.

This is a breaking change because invalid OpenSSH keys
have been tolerated since the very beginning, when Shawn introduced
the SSH support in Change 6610.
Attempting to store new invalid SSH keys would fail and result
an HTTP status 400 error as response to the add keys REST-API.

Make SshKeyCacheImpl tolerant to existing keys stored
in the accounts' profile, otherwise Gerrit may start flagging
keys that have been previously stored as invalid, resulting
in random authentication failures by existing users.

Existing invalid keys are reported in the error_log with the
associated exceptions and automatically fixed, removing the
invalid key from the accounts profile and adjusting the key
algorithm with the one associated with the public key.

Release-Notes: Breaking change: validate and reject SSH keys with invalid or mismatched algorithm

Gerrit Code Review

Gerrit is a code review and project management tool for Git based projects.

Build Status Maven Central

Objective

Gerrit makes reviews easier by showing changes in a side-by-side display, and allowing inline comments to be added by any reviewer.

Gerrit simplifies Git based project maintainership by permitting any authorized user to submit changes to the master Git repository, rather than requiring all approved changes to be merged in by hand by the project maintainer.

Documentation

For information about how to install and use Gerrit, refer to the documentation.

Source

Our canonical Git repository is located on googlesource.com. There is a mirror of the repository on Github.

Reporting bugs

Please report bugs on the issue tracker.

Contribute

Gerrit is the work of hundreds of contributors. We appreciate your help!

Please read the contribution guidelines.

Note that we do not accept Pull Requests via the Github mirror.

Getting in contact

The Developer Mailing list is repo-discuss on Google Groups.

License

Gerrit is provided under the Apache License 2.0.

Build

Install Bazel and run the following:

    git clone --recurse-submodules https://gerrit.googlesource.com/gerrit
    cd gerrit && bazel build release

Install binary packages (Deb/Rpm)

The instruction how to configure GerritForge/BinTray repositories is here

On Debian/Ubuntu run:

    apt-get update & apt-get install gerrit=<version>-<release>

NOTE: release is a counter that starts with 1 and indicates the number of packages that have been released with the same version of the software.

On CentOS/RedHat run:

    yum clean all && yum install gerrit-<version>[-<release>]

On Fedora run:

    dnf clean all && dnf install gerrit-<version>[-<release>]

Use pre-built Gerrit images on Docker

Docker images of Gerrit are available on DockerHub

To run a CentOS 8 based Gerrit image:

    docker run -p 8080:8080 gerritcodereview/gerrit[:version]-centos8

To run a Ubuntu 20.04 based Gerrit image:

    docker run -p 8080:8080 gerritcodereview/gerrit[:version]-ubuntu20

NOTE: release is optional. Last released package of the version is installed if the release number is omitted.
