[jira] [Created] (ARROW-14467) [C++][Python][Parquet] Uniform encryption

Maya Anderson created ARROW-14467:
-------------------------------------

             Summary: [C++][Python][Parquet] Uniform encryption
                 Key: ARROW-14467
                 URL: https://issues.apache.org/jira/browse/ARROW-14467
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++, Parquet, Python
            Reporter: Maya Anderson
            Assignee: Maya Anderson


PME supports using the same encryption key for all columns, which is useful in a number of scenarios. However, misuse of this feature can break the NIST limit on the number of AES GCM operations with one key, as reported in PARQUET-2040. We will develop a limit-enforcing code and provide a Python API for uniform encryption, similarly to PARQUET-2040 and based on ARROW-9947.
