ByteArrayFixedIvGenerator

java.lang.Object
- org.jasypt.iv.ByteArrayFixedIvGenerator

All Implemented Interfaces:

FixedIvGenerator, IvGenerator
```
public class ByteArrayFixedIvGenerator
extends java.lang.Object
implements FixedIvGenerator
```
Byte-array based implementation of FixedIvGenerator, that will always return the same initialization vector (IV).

If the requested IV has a size in bytes smaller than the specified IV, the first n bytes are returned. If it is larger, an exception is thrown.

This class is thread-safe.

Since:

1.9.3

Modifier and Type	Method	Description
`byte[]`	`generateIv(int lengthBytes)`	Return iv with the specified byte length.
`boolean`	`includePlainIvInEncryptionResults()`	As this iv generator provides a fixed iv, its inclusion unencrypted in encryption results is not necessary, and in fact not desirable (so that it remains hidden).
