AesKey (bitcoinj-core 0.17-alpha1 API)

java.lang.Object
- org.bitcoinj.crypto.AesKey

```
public class AesKey
extends java.lang.Object
```
Wrapper for a byte[] containing an AES Key. This is a replacement for Bouncy Castle's KeyParameter which was used for this purpose in previous versions of bitcoinj. Unfortunately, this created a Gradle _API_ dependency on Bouncy Castle when that wasn't strictly necessary.
We have made this change without deprecation because it affected many method signatures and because updating is a trivial change. If for some reason you have code that uses the Bouncy Castle KeyParameter type and need to convert to or from AesKey, you can temporarily use ofKeyParameter(KeyParameter) or toKeyParameter()

public AesKey(byte[] keyBytes)
```
    Wrapper for a byte[] containing an AES Key
    
    Parameters:
    
    keyBytes - implementation-dependent AES Key bytes
- Method Detail
  - bytes
```
public byte[] bytes()
```
    Returns:
    
    The key bytes
  - getKey
```
@Deprecated
public byte[] getKey()
```
    Deprecated.
    Use bytes()
    
    Provided to ease migration from KeyParameter.
    
    Returns:
    
    The key bytes
  - ofKeyParameter
```
@Deprecated
public static AesKey ofKeyParameter(org.bouncycastle.crypto.params.KeyParameter keyParameter)
```
    Deprecated.
    Use new AesKey(keyParameter.bytes())
    
    Provided to ease migration from KeyParameter.
    
    Parameters:
    
    keyParameter - instance to convert
    
    Returns:
    
    new, preferred container for AES keys
  - toKeyParameter
```
@Deprecated
public org.bouncycastle.crypto.params.KeyParameter toKeyParameter()
```
    Deprecated.
    Use new KeyParameter(key.bytes)
    
    Provided to ease migration from KeyParameter.
    
    Returns:
    
    if for some reason you still need (temporarily, we hope) a KeyParameter
