EncryptContent should be able to decrypt signed files

Hello,
processor EcryptContent is excelent solution to add extra layer of security when there is a need, for example, to exchange files outside own infrastructure. But files enrypted by it, cannot be signed.
And this is not such a big issue. More problematic is, when we are trying process files from others, which is signed. Then NiFi throws exception "encrypted message contains a signed message - not literal data.". (here: gitlab)
Allright, i know that maybe adding support for public keyrings, checking signatures etc needs extra development, but maybe there should be extra checkbox in proessor configuration "ignore signatures" which can give us posibillity to read encrypted files, even if they are signed?
