public void clear()

Implements org.eclipse.jgit.lib.SignatureVerifier.clear.

Doc from org.eclipse.jgit.lib.SignatureVerifier.clear.

A SignatureVerifier may cache public keys to speed up verifying signatures on multiple objects. This clears this cache, if any.

public String getName()

Implements org.eclipse.jgit.lib.SignatureVerifier.getName.

Doc from org.eclipse.jgit.lib.SignatureVerifier.getName.

Retrieves the name of this verifier. This should be a short string identifying the engine that verified the signature, like "gpg" if GPG is used, or "bc" for a BouncyCastle implementation.

Returns:String

the name

Implements org.eclipse.jgit.lib.SignatureVerifier.verify.

Doc from org.eclipse.jgit.lib.SignatureVerifier.verify.

Verifies a given signature for given data.

Parameters
repository:Repository

the Repository the data comes from.
