HMAC256Generator.HMACKey (I2P Anonymous Network - Java Documentation - Version 1.5.0)

java.lang.Object
- net.i2p.crypto.HMAC256Generator.HMACKey

All Implemented Interfaces:

Serializable, Key, SecretKey, Destroyable

Enclosing class:

HMAC256Generator
```
static final class HMAC256Generator.HMACKey
extends Object
implements SecretKey
```
Like SecretKeySpec but doesn't copy the key in the construtor, for speed. It still returns a copy in getEncoded(), because Mac relies on that, doesn't work otherwise. First 32 bytes are returned in getEncoded(), data may be longer.

Since:

0.9.38
