sign

public void sign(@NonNull
                 CommitBuilder commit,
                 @Nullable
                 java.lang.String gpgSigningKey,
                 @NonNull
                 PersonIdent committer,
                 CredentialsProvider credentialsProvider)
          throws CanceledException

Description copied from class: GpgSigner

Signs the specified commit.

Implementors should obtain the payload for signing from the specified commit via CommitBuilder.build() and create a proper GpgSignature. The generated signature must be set on the specified commit (see ObjectBuilder.setGpgSignature(GpgSignature)).

Any existing signature on the commit must be discarded prior obtaining the payload via CommitBuilder.build().

Specified by:

sign in class GpgSigner

Parameters:

commit - the commit to sign (must not be null and must be complete to allow proper calculation of payload)

gpgSigningKey - the signing key to locate (passed as is to the GPG signing tool as is; eg., value of user.signingkey)

committer - the signing identity (to help with key lookup in case signing key is not specified)

credentialsProvider - provider to use when querying for signing key credentials (eg. passphrase)

Throws:

CanceledException - when signing was canceled (eg., user aborted when entering passphrase)

signObject

public void signObject(@NonNull
                       ObjectBuilder object,
                       @Nullable
                       java.lang.String gpgSigningKey,
                       @NonNull

                       GpgConfig config)
                throws CanceledException,
                       UnsupportedSigningFormatException

Description copied from interface: GpgObjectSigner

Signs the specified object.

Implementors should obtain the payload for signing from the specified object via ObjectBuilder.build() and create a proper GpgSignature. The generated signature must be set on the specified object (see ObjectBuilder.setGpgSignature(GpgSignature)).

Any existing signature on the object must be discarded prior obtaining the payload via ObjectBuilder.build().

Specified by:

signObject in interface GpgObjectSigner

Parameters:

object - the object to sign (must not be null and must be complete to allow proper calculation of payload)

gpgSigningKey - the signing key to locate (passed as is to the GPG signing tool as is; eg., value of user.signingkey)

committer - the signing identity (to help with key lookup in case signing key is not specified)

credentialsProvider - provider to use when querying for signing key credentials (eg. passphrase)

config - GPG settings from the git config

Throws:

CanceledException - when signing was canceled (eg., user aborted when entering passphrase)

UnsupportedSigningFormatException - if a config is given and the wanted key format is not supported
