Method Detail

decrypt

public static ByteBuffer decrypt(ByteBuffer data)

Decrpyt the specified data buffer. This method returns a byte buffer instead of a string so that the caller can set the buffer to null once it is not longer in useful scope. Doing so will help to narrow the window in which vulnerable information resides in memory.

Parameters:

data -

Returns:

a byte buffer with the encrypted data.

decrypt

public static ByteBuffer decrypt(ByteBuffer data,
                                 byte[] key)

Decrpyt the specified data buffer. This method returns a byte buffer instead of a string so that the caller can set the buffer to null once it is not longer in useful scope. Doing so will help to narrow the window in which vulnerable information resides in memory.

Parameters:

data -

Returns:

a byte buffer with the encrypted data.

encrypt

public static ByteBuffer encrypt(byte[] data,
                                 byte[] key)

Encrypt the data using the key

Parameters:

data -

key -

Returns:

the encrypted payload

encrypt

public static ByteBuffer encrypt(ByteBuffer data,
                                 byte[] key)

Encrypt the data using the key

Parameters:

data -

key -

Returns:

the encrypted payload

encrypt
