As reported on the mailing lists , prior to 0.5.1, users could provide the path to an individual PGP public key file (i.e. exportedPublicKey.asc) as the Public Keyring File property in the EncryptContent processor. With
NIFI-1324, the handling of the keyring files became more strict. While this follows the explicit naming of the property, some users may have individual keys rather than the keyring file.
Add logic to support individual key handling for public and secret keys in EncryptContent processor via OpenPGPKeyBasedEncryptor.
