HW/Cloudera support has responded with
"As per Apache NiFi documentation, EncryptContent process 1.9.0 does not supports DSA 1024 bit algorithm for encryption."
and a link to the Apache EncryptContent processor
Problem is we have a number of clients using DSA 1024 under pgp/gpg and we'd really prefer to encrypt with NiFI.
Does anyone ( Andy Lopresto are you listening?) know if this is a fundamental incompatibility with DSA, a legal issue (see RSA patent fights of the 2000's), or simply an algorithm that has yet to be implemented?
