mccheah opened a new issue #20: Encryption in Data Files URL: https://github.com/apache/incubator-iceberg/issues/20 We want to support encrypting and decrypting data that is recorded in Iceberg tables. There are several API extensions that we can consider to make this work: - Define a `KeyReference` field, which is a byte blob in the `DataFile` object. A `KeyReference` is a pointer to a key. - Define an `EncryptionKey` which is a composition of the key bytes, the iv, and the key algorithm (see e.g. [here](https://github.com/palantir/hadoop-crypto/blob/develop/crypto-keys/src/main/java/com/palantir/crypto2/keys/KeyMaterial.java#L28) and [here](https://github.com/palantir/hadoop-crypto/blob/b6b1680a003c23bdd0ce0b01a394eacd95eb0e9d/crypto-keys/src/main/java/com/palantir/crypto2/keys/serialization/KeyMaterials.java#L53)) ``` struct EncryptionKey { byte[] encodedKey(); String keyAlgorithm(); byte[] iv(); } ``` - Define a `KeyManager` which manages creating new keys and retrieving keys based on key references. The `TableOperations` API should support returning an `Optional<KeyManager>`; return `Optional.empty()` if the table operations doesn't support encryption. ``` struct CreatedKey { EncryptionKey key(); byte[] keyReference(); } interface KeyManager { CreatedKey createKey(String pathToEncrypt); EncryptionKey getKey(KeyReference reference); } ```
