Subject Re: EncryptContent issues after NIFI-1257 and NIFI-1259
Date Tue, 29 Mar 2016 01:24:14 GMT
Forgot to mention you’ll want to change the input/output directories in the GetFile and PutFile
processors, as well as the paths to the public and secret keyring, the user ID, and the password
for the EncryptContent processors.

Algorithm” is set to “PGP” or “PGP_ASCII_ARMOR”. The KDF is required for symmetric
encryption (deriving a key from the provided password), but not used for PGP encryption/decryption
at all. Unfortunately, we cannot currently display/hide or change the required-ness of processor
properties based on the value of other properties. There is an existing Jira open [1] to enhance
this functionality. Perhaps this can be better documented in the Admin Guide [2].

That didn't work.
