public interface EncryptionManager
extends java.io.Serializable
```
Module for encrypting and decrypting table data files.
This must be serializable because an instance may be instantiated in one place and sent across the wire in some Iceberg integrations, notably Spark.

Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`default java.lang.Iterable<InputFile>`	`decrypt(java.lang.Iterable<EncryptedInputFile> encrypted)`	Variant of `decrypt(EncryptedInputFile)` that provides a sequence of files that all need to be decrypted in a single context.
`InputFile`	`decrypt(EncryptedInputFile encrypted)`	Given an `EncryptedInputFile.encryptedInputFile()` representing the raw encrypted bytes from the underlying file system, and given metadata about how the file was encrypted via `EncryptedInputFile.keyMetadata()`, return an `InputFile` that returns decrypted input streams.
`default java.lang.Iterable<EncryptedOutputFile>`	`encrypt(java.lang.Iterable<OutputFile> rawOutput)`	Variant of `encrypt(OutputFile)` that provides a sequence of files that all need to be encrypted in a single context.
`EncryptedOutputFile`	`encrypt(OutputFile rawOutput)`	Given a handle on an `OutputFile` that writes raw bytes to the underlying file system, return a bundle of an `EncryptedOutputFile.encryptingOutputFile()` that writes encrypted bytes to the underlying file system, and the `EncryptedOutputFile.keyMetadata()` that points to the encryption key that is being used to encrypt this file.

InputFile decrypt(EncryptedInputFile encrypted)
```
    Given an EncryptedInputFile.encryptedInputFile() representing the raw encrypted bytes from the underlying file system, and given metadata about how the file was encrypted via EncryptedInputFile.keyMetadata(), return an InputFile that returns decrypted input streams.
  - decrypt
```
default java.lang.Iterable<InputFile> decrypt(java.lang.Iterable<EncryptedInputFile> encrypted)
```
    Variant of decrypt(EncryptedInputFile) that provides a sequence of files that all need to be decrypted in a single context.
    By default this calls the single-file decryption method for each element in the iterator. Implementations can override this for a variety of optimizations. For example, an implementation can perform lookahead on the input iterator and fetch encryption keys in batch.
