# Encrypted test data

`manifest-list-v3-encrypted.avro` is an empty manifest list encrypted by iceberg-rust, copied from its
`crates/iceberg/testdata/manifests_lists/`. It was written by iceberg-rust's `EncryptionManager`, with a memory KMS
holding master key `master-1` = bytes `0x00` to `0x0f`. Its keys and snapshot are in the
`example_table_metadata_v3_encrypted` fixture in `tests/conftest.py`.

`manifest-v3-encrypted.avro` is a v3 data manifest with two added entries, written and encrypted by iceberg-rust's
`ManifestWriter` with key `0123456789abcdef` and AAD prefix `fedcba9876543210`. The key metadata that its manifest list
entry would record is in `test_read_manifest_encrypted_by_iceberg_rust` in `tests/utils/test_manifest.py`.

`data-v3-encrypted.parquet` is a Parquet data file with three rows, written and encrypted by iceberg-rust's
`ParquetWriter` with a key from its `EncryptionManager`. The key metadata that its manifest entry would record is in
`test_task_to_record_batches_encrypted_by_iceberg_rust` in `tests/io/test_pyarrow.py`.

`dv-v3-encrypted.puffin` is a Puffin file with one deletion vector, deleting positions 1, 3 and 5 of
`s3://bucket/table/data/00000.parquet`. It was written and encrypted by iceberg-rust's `PuffinWriter` with key
`0123456789abcdef` and AAD prefix `fedcba9876543210`. The key metadata that its manifest entry would record is in
`test_read_deletes_from_puffin_file_encrypted_by_iceberg_rust` in `tests/io/test_pyarrow.py`.
