    Description copied from interface: ISymCipher
    
    Sets the AES encryption key to the value in the key buffer. Required length and error handling is implementation specific.
    
    Specified by:
    
    setEncryptionKeyAES in interface ISymCipher
    
    Returns:
    
    0 if successful, -1 if an error occurred
  - setEncryptionKeyAES
```
public int setEncryptionKeyAES(byte[] key,
                               int offset,
                               int len)
```
    Specified by:
    
    setEncryptionKeyAES in interface ISymCipher
    
    Parameters:
    
    key - byte[]
    
    offset - int
    
    len - int if len==16 --> only the key is set; if len==32 --> key and IV is set
    
    Returns:
    
    int
  - setEncryptionKeysAES
```
public int setEncryptionKeysAES(byte[] keys)
```
    Set both keys to different value, if keys.length==2* KEY_SIZe, else set both keys to the same value
    
    Specified by:
    
    setEncryptionKeysAES in interface ISymCipher
    
    Parameters:
    
    keys - byte[]
    
    Returns:
    
    int
  - getKeys
```
public byte[] getKeys()
```
    Returns the currently used key(s) for encryption. If both keys are set, than an array of 32 byte is returned, otherwise an array of 16 bytes
    
    Specified by:
    
    getKeys in interface ISymCipher
    
    Returns:
    
    The current key(s) used for encryption or null, if no key is set.
