Avro files are coming from source as flowfiles in Apache Nifi and i want to fetch 'Password' column and hash it with 'SHA2-256' and give it as an output flowfile and finally put it in AWS s3.

  1. You can modify the content of an individual "column" of Avro data (or any record format in NiFi) with the UpdateRecord processor.
  2. You should not be doing this. SHA-256 is a cryptographic hash function but it is not designed for nor safe for "password hashing". Taking passwords, running them through a single SHA-256 digest function, and putting them on an S3 bucket is a very bad and very unsafe idea. Do not do it. Research how password hashing works before implementing any password protection.
