public interface GpgObjectSigner

Creates GPG signatures for Git objects.

Since:

5.11

Method Summary

Modifier and Type	Method and Description
boolean	canLocateSigningKey(String gpgSigningKey, PersonIdent committer, CredentialsProvider credentialsProvider, GpgConfig config) Indicates if a signing key is available for the specified committer and/or signing key.
void	signObject(ObjectBuilder object, String gpgSigningKey, PersonIdent committer, CredentialsProvider credentialsProvider, GpgConfig config) Signs the specified object.

Method Detail

signObject

void signObject(@NonNull
                ObjectBuilder object,
                @Nullable
                String gpgSigningKey,
                @NonNull
                PersonIdent committer,
                CredentialsProvider credentialsProvider,
                GpgConfig config)
         throws CanceledException,
                UnsupportedSigningFormatException

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().

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

canLocateSigningKey

boolean canLocateSigningKey(@Nullable
                            String gpgSigningKey,
                            @NonNull
                            PersonIdent committer,
                            CredentialsProvider credentialsProvider,
                            GpgConfig config)
                     throws CanceledException,
                            UnsupportedSigningFormatException

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)

config - GPG settings from the git config

Returns:

true if a signing key is available, false otherwise

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
