25 /**
26  * An unsafe archive driver which builds RAES encrypted ZIP32 archives.
27  * This class only authenticates the cipher key and file length, which makes
28  * it comparably fast.
29  * However, it does <em>not</em> check the cipher text of input archives and
30  * does <em>not</em> check the CRC-32 values of the encrypted archive entries,
31  * so it's completely unsafe.
32  * <p>
33  * Instances of this class are immutable.
34  *
35  * @deprecated This class exists for testing purposes only.
36  * You should never use this class - use {@link SafeZip32RaesDriver}
37  * instead.
38  * @see SafeZip32RaesDriver
39  * @see ParanoidZip32RaesDriver
