Method Detail

getDefault

public static GpgSigner getDefault()

Get the default signer, or null.

Returns:

the default signer, or null.

setDefault

public static void setDefault(GpgSigner signer)

Set the default signer.

Parameters:

signer - the new default signer, may be null to select no default.

sign

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

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().

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)

canLocateSigningKey

public abstract boolean canLocateSigningKey(@Nullable
                                            String gpgSigningKey,
                                            @NonNull
                                            PersonIdent committer,
                                            CredentialsProvider credentialsProvider)
                                     throws CanceledException

Indicates if a signing key is available for the specified committer and/or signing key.

Parameters:

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)

Returns:

true if a signing key is available, false otherwise

Throws:

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