Imports
org.bouncycastle.openpgp.PGPSignatureSubpacketGenerator, .PGPSignatureSubpacketVector
Callback to modify the contents of a PGPSignatureSubpacketGenerator. The OpenPGPV6KeyGenerator 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.

Method Detail

applyback to summary
public 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:PGPSignatureSubpacketGenerator
