Interface SignatureSubpacketsFunction

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface SignatureSubpacketsFunction

Callback to modify the contents of a PGPSignatureSubpacketGenerator. The OpenPGPKeyGenerator already prepopulates the hashed subpacket areas of signatures during key generation. This callback is useful to apply custom changes to the hashed subpacket area during the generation process.

PGPSignatureSubpacketGenerator	apply(PGPSignatureSubpacketGenerator subpackets)	Apply some changes to the given PGPSignatureSubpacketGenerator and return the result.

Method Details

apply

PGPSignatureSubpacketGenerator apply(PGPSignatureSubpacketGenerator subpackets)

Apply some changes to the given PGPSignatureSubpacketGenerator and return the result. It is also possible to replace the whole PGPSignatureSubpacketGenerator by returning another instance. Tipp: In order to replace a subpacket, make sure to prevent duplicates by first removing subpackets of the same type using PGPSignatureSubpacketGenerator.removePacketsOfType(int). To inspect the current contents of the generator, it is best to call PGPSignatureSubpacketGenerator.generate() and in turn inspect its contents using PGPSignatureSubpacketVector.toArray().

Parameters:

subpackets - original subpackets

Returns:

non-null modified subpackets
