Since Spark 3.2, columnar encryption is supported for Parquet tables with Apache Parquet 1.12+. Parquet uses the envelope encryption practice, where file parts are encrypted with "data encryption keys" (DEKs), and the DEKs are encrypted with "master encryption keys" (MEKs). The DEKs are randomly generated by Parquet for each encrypted. Familiar with Apache Spark.
