David Handermann updated NIFI-8319:
-----------------------------------
Status: Patch Available (was: In Progress)
> 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
> Priority: Major
> Labels: encryption, security
> Time Spent: 10m
> Remaining Estimate: 0h
>
> 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.
