## org.apache.poi.poifs.crypt.temp
Class AesZipFileZipEntrySource

    java.lang.Object
      org.apache.poi.poifs.crypt.temp.AesZipFileZipEntrySource

All Implemented Interfaces:
  java.io.Closeable, ZipEntrySource

    @Beta
    public class AesZipFileZipEntrySource

extends java.lang.Object
implements ZipEntrySource

An example `ZipEntrySource` that has encrypted temp files to ensure that sensitive data is not stored in raw format on disk.

Constructor Summary
`AesZipFileZipEntrySource(java.io.File tmpFile, javax.crypto.Cipher ci)`

Method Summary
`void` | `close()` Indicates we are done with reading, and resources may be freed
`static AesZipFileZipEntrySource` | `createZipEntrySource(java.io.InputStream is)`
`java.util.Enumeration<? extends java.util.zip.ZipEntry>` | `getEntries()` Note: the file sizes are rounded up to the next cipher block size, so don't rely on file sizes of these custom encrypted zip file entries!
`java.io.InputStream` | `getInputStream(java.util.zip.ZipEntry entry)` Returns an InputStream of the decompressed data that makes up the entry
`boolean` | `isClosed()` Has close been called already?
