[jira] [Created] (NIFI-8319) EncryptContent should support decrypting AES/CBC/NoPadding

David Handermann created NIFI-8319:
--------------------------------------

             Summary: EncryptContent should support decrypting AES/CBC/NoPadding
                 Key: NIFI-8319
                 URL: https://issues.apache.org/jira/browse/NIFI-8319
             Project: Apache NiFi
          Issue Type: New Feature
          Components: Security
    Affects Versions: 1.13.0
            Reporter: David Handermann
            Assignee: David Handermann


The {{EncryptContent}} Processor current supports {{AES_CBC}} as an option for the {{Encryption Algorithm}} property. This option translates to the use of {{AES/CBC/PKCS7Padding}} as the cipher algorithm for encryption or decryption.

Supporting decryption using {{AES/CBC/NoPadding}} will allow integration with external systems requiring the use of that particular cipher algorithm. Encryption support for {{AES/CBC/NoPadding}} is not recommended due to potential padding vulnerabilities in AES-CBC as well as the requirement for padding input to match the required cipher block size.
