Thomas Wolf 3774fcc848 GPG signature verification via BouncyCastle Add a GpgSignatureVerifier interface, plus a factory to create instances thereof that is provided via the ServiceLoader mechanism. Implement the new interface for BouncyCastle. A verifier maintains an internal LRU cache of previously found public keys to speed up verifying multiple objects (tag or commits). Mergetags are not handled. Provide a new VerifySignatureCommand in org.eclipse.jgit.api together with a factory method Git.verifySignature(). The command can verify signatures on tags or commits, and can be limited to accept only tags or commits. Provide a new public WrongObjectTypeException thrown when the command is limited to either tags or commits and a name resolves to some other object kind. In jgit.pgm, implement "git tag -v", "git log --show-signature", and "git show --show-signature". The output is similar to command-line gpg invoked via git, but not identical. In particular, lines are not prefixed by "gpg:" but by "bc:". Trust levels for public keys are read from the keys' trust packets, not from GPG's internal trust database. A trust packet may or may not be set. Command-line GPG produces more warning lines depending on the trust level, warning about keys with a trust level below "full". There are no unit tests because JGit still doesn't have any setup to do signing unit tests; this would require at least a faked .gpg directory with pre-created key rings and keys, and a way to make the BouncyCastle classes use that directory instead of the default. See bug 547538 and also bug 544847. Tested manually with a small test repository containing signed and unsigned commits and tags, with signatures made with different keys and made by command-line git using GPG 2.2.25 and by JGit using BouncyCastle 1.65.

Thomas Wolf 3774fcc848 GPG signature verification via BouncyCastle

Add a GpgSignatureVerifier interface, plus a factory to create
instances thereof that is provided via the ServiceLoader mechanism.

Implement the new interface for BouncyCastle. A verifier maintains
an internal LRU cache of previously found public keys to speed up
verifying multiple objects (tag or commits). Mergetags are not handled.

Provide a new VerifySignatureCommand in org.eclipse.jgit.api together
with a factory method Git.verifySignature(). The command can verify
signatures on tags or commits, and can be limited to accept only tags
or commits. Provide a new public WrongObjectTypeException thrown when
the command is limited to either tags or commits and a name resolves
to some other object kind.

In jgit.pgm, implement "git tag -v", "git log --show-signature", and
"git show --show-signature". The output is similar to command-line
gpg invoked via git, but not identical. In particular, lines are not
prefixed by "gpg:" but by "bc:".

Trust levels for public keys are read from the keys' trust packets,
not from GPG's internal trust database. A trust packet may or may
not be set. Command-line GPG produces more warning lines depending
on the trust level, warning about keys with a trust level below
"full".

There are no unit tests because JGit still doesn't have any setup to
do signing unit tests; this would require at least a faked .gpg
directory with pre-created key rings and keys, and a way to make the
BouncyCastle classes use that directory instead of the default. See
bug 547538 and also bug 544847.

Tested manually with a small test repository containing signed and
unsigned commits and tags, with signatures made with different keys
and made by command-line git using GPG 2.2.25 and by JGit using
BouncyCastle 1.65.
